Internship in Nestlé - 30th Dec 2016 (8am - 5pm)

At 9.15 a.m., we had a meeting with the operators. Before the end of the meeting, as today is the last working day of 2016, Tee thanked the operators for their cooperation and contributions to the team throughout this year.

At 10.00 a.m., I conducted pipeline tracing in the DPRS site to be fully familiar with the flow and location of each equipment.

At 11.30 a.m., Tee asked me to do the calculation of the amount of chemicals required for the flocculation and coagulation using a jar tester. I am planning to understand the information of the jar tester in advance.

At 11.45 a.m., I went to WWTP to observe the existing DAF unit. Jaclyn and the operator Desa were monitoring the water condition in the flocculator. They managed to obtain a clear solution with floating flocs when adding the flocculants (polymers) into a bottle of water sample taken from DAF influent, but the same result was not shown for a water sample taken from the flocculator after the chemical dosing. Eventually, they managed to get the same outcome after several trials and errors.

At 3.00 p.m., I met Tee and Jaclyn in the WWTP control room. Tee conducted a simple experiment with a water sample taken from a sludge recirculation pit to observe various types of microorganisms using a microscope. He showed us the bacteria and metazoan such as rotifer. I had an opportunity to observe the rotifer swimming freely, using a microscope.

The rotifers are often found in extended aeration-activated sludge (EAAS) systems with older sludge. Their principal role in wastewater is to develop floc stabilization. Their presence indicates a good, stable sludge with plenty of oxygen. Rotifers are good indicators of wastewater toxicity as they are sensitive to toxic loads, however, they should never be dominant in the system.

At 4.00 p.m., Jaclyn and I went to the DPRS site. At the same time, the construction of a new above-ground pipeline is carried on to replace the old, broken underground pipeline.

Internship in Nestlé - 29th Dec 2016 (8am - 5pm)

At 9.15 a.m., we had a short meeting with the operators.

At 10.00 a.m., I did observation in the WWTP and installation sites. The mechanical aerator of the second aeration was not running because one of the bolts to support the aerator was broken.

At 11.00 a.m., Tee gave me a new 3M safety helmet (white pin-lock suspension) to replace the expired hard helmet which I used currently. I learnt and followed the manual instructions to assemble the new safety helmet.

New safety helmet

At 2.00 p.m., Tee had signed and returned my weekly log sheets of Week 1 - 5 to me with comments. He told me that in the following weeks (at the beginning of the next year 2017), we would be busy due to the arrival of a new DAF unit and the commissioning procedure of DPRS.

At 2.45 p.m., Jaclyn and I went to the WWTP control room. She showed me the daily recording which contains flowrate and water parameters such as pH, COD, MLSS etc. She explained the purpose of data recording and shared some information.

For example, the colour of the DAF influent (measured in terms of American Dye Manufacturers' Institute or ADMI) has to be recorded, but not the colour of the influent of other balance tanks. This is because the colour of the final discharge (to the environment) is also one of the parameters to be monitored. Since DAF influent mainly consists of wastewater from coffee production and is relatively darker than the others, it is necessary to monitor the colour of DAF influent in the early stage.

At 3.15 p.m., we observed the contractors to replace a new bolt. The mechanical aerator of the second aeration tank was locked by LOTO to prevent any accident. They also greased the joints of the metal support of this aerator to reduce the noise and ensure a prolonged operation of the aerator.

Internship in Nestlé - 27-28th Dec 2016 (8am - 5pm)

Tuesday, 27^th Dec 2016 (8am - 5pm)

At 8.15 a.m., I received an email from Tee with the attached file of the Maintenance Plan after being checked by him. He wanted me to update and complete the remaining parts. He also attached the Portable Document Format (PDF) of the P&ID of reverse osmosis (RO) and chlorine dioxide generation and dosing system for my own reference.

At 9.15 a.m., we had a daily review meeting with the operators.

At 10.15 a.m., I observed and recorded the information on the remaining equipment at the DPRS site. Currently, three projects are carried on now in WWTP, which are the installation of a new DAF, DPRS and sludge dewatering system.

Online TOC (Total Organic Carbon) Analyser (taken at the same day)

At 1.30 p.m., I read the book CePIETSO (Biological Processes) and studied the working concepts of the performance monitoring of common biological treatment processes. The definitions and formulae of water parameters are clearly explained, such as biochemical oxygen demand (BOD), chemical oxygen demand (COD), sludge volume index (SVI), mixed liquor suspended solids (MLSS), etc.

At 3.40 p.m., I went to WWTP again to observe the DPRS process.

Wednesday, 28^th Dec 2016 (8am - 5pm)

At 9.15 a.m., we had a meeting with the operators. The WWTP operator had reported that an oil layer was observed at the balance tank recently.

At 10.00 a.m., I went to the DPRS as usual and recorded the information of the remaining equipment which is available. The task of updating the Maintenance Plan file is ongoing once I collected the data from the DPRS site.

At 1.45 p.m., I read the book CePIETSO (Biological Processes) to learn the examples of calculation of water parameters for the performance monitoring of common biological treatment processes, such as BOD, COD, SVI, MLSS, etc.

At 3.00 p.m., I conducted pipeline tracing in the DPRS site with the aid of P&ID on hands and observed the existing WWTP. I have to be familiar with the detail and location of each equipment in DPRS for the preparation of commissioning in the future. 

Internship in Nestlé - 23rd Dec 2016 (8am - 5pm)

At 9.15 a.m., as usual, we had a meeting with the operators.

At 10.00 a.m., Tee asked me about my progress in preparing the Maintenance Plan and said that he would check it this afternoon. Then I read the book CePIETSO (Biological Processes) which contains information about water treatment. This book consists of many modules and formulae for calculating water parameters.

At 2.00 p.m., Jaclyn told me that she had received the P&ID of the sludge dewatering system. This system is under installation now. She shared this P&ID and briefly explained the process of sludge dewatering to me. I took this opportunity to study sludge management in the industrial sector.

At 2.30 p.m., Jaclyn and I went to the DPRS site to observe and study the process flow again with the aid of P&ID while looking around the existing WWTP. We realized several alterations during the installation of instruments and differences with the arrangement as shown in P&ID.

At 3.30 p.m., we noticed that water was turbid at the second final discharge point. We also realized that there was a sludge overflow at the second clarifier. We quickly opened the valve fully to allow the sediment sludge to flow out from the clarifier for a certain time. Eventually water flow at all final discharge points were clear.

At 4.45 p.m., I emailed the Maintenance Plan to Tee and Jaclyn for checking.

Internship in Nestlé - 21st & 22nd Dec 2016 (8am - 5pm)

Wednesday, 21^st Dec 2016 (8am - 5pm)

At 9.15 a.m., as usual, we had a meeting with the operators. During the safety section, the WWTP operator Desa brought up an issue that it is dangerous when taking the data from the flowmeter installed along the pipeline of the wastewater source as there is a metal bar nearby for the DPRS installation. This issue was recorded down and to be solved.

At 10.00 a.m., I went to the DPRS site to observe and do the pipeline tracing for the upstream (MBRs) again while checking the information I had gathered previously. I updated the Excel file of the Maintenance Plan in the office.

At 11.00 a.m., I began to study and summarize the process description of DPRS and made my own notes for my understanding of the knowledge of DPRS.

At 3.00 p.m., I continued the information checking while observing the remaining part of DPRS, which is the RO system. The installation was ongoing and the chemical dosing systems had not been installed yet.

At 4.00 p.m., I went back to the office while updating the Excel file. Jaclyn had told me that our country, Malaysia is the third country to install the DPRS in water treatment in Nestlé, which is under construction now. DPRS is an advanced technology that reuses and recycles clean water for other purposes as an effort for water sustainable development.

Thursday, 22^nd Dec 2016 (8am - 5pm)

At 8.30 a.m., my colleagues Shanji and Jaclyn asked me about my progress on the current task. I had reported to them that certain information was unavailable. We decided to visit the DPRS installation site together this afternoon.

At 9.15 a.m., as usual, we had a meeting with the operators. They had informed us of any issues in their working sites.

At 10.00 a.m., I studied the DPRS process and the function of each equipment, including the purpose of chemical dosing systems using the P&IDs and site layout. This aids me in further understanding the process for my following tasks in the future.

At 2.30 p.m., it was cloudy but three of us still visited the DPRS site to study and trace the pipelines together. I shared my understanding of DPRS with them. We discussed among each other about the existing WWTP and DPRS. Shanji also shared his industrial experience when he observed something at the site.

At the end of the visit, I was glad as they thanked me that I had done a great job of guiding them to understand the process more easily. Throughout the task, I found it very interesting to study P&ID and conduct pipeline tracing of process systems in the actual site at the same time. 

Installation was undergoing (taken at the same day)

Internship in Nestlé - 19-20th Dec 2016 (8am - 5pm)

Monday, 19^th Dec 2016 (8am - 5pm)

At 9.15 a.m., we had a meeting in the absence of Tee as he was attending a training course for a few days.

At 9.45 a.m., I went to the direct potable reuse system (DPRS) installation site to observe the equipment and instruments after wearing personal protective equipment (PPE), such as a safety helmet, earplug and reflective vest. Around this time the workers were having a short break, so it was convenient for me to trace the pipelines and record the information of equipment and instruments, such as serial numbers and dimensions. This time I only managed to study the upstream of DPRS, which mainly consists of post-treatment aeration basin and membrane bioreactors (MBRs).

Example photo of equipment with serial number

Pressure gauge

At 11.15 am, I analyzed and typed the information recorded just now into the Excel file that was created last week.

At 2.30 p.m., it was after raining. I continued to collect the information on the DPRS site. This time I managed to observe the downstream, which consists of the reverse osmosis (RO) system.

At 4.00 p.m., I analyzed the information before typing it into the Excel file. There was much information to be processed as there were many equipment and instruments.

Tuesday, 20^th Dec 2016 (8am - 5pm)

At 8.30 a.m., Bhajan distributed the form of Behavioral Observation (Pemerhatian Perilaku) to all colleagues. He told me that I could fill in the form as feedback to him when noticing any issues relating to safety within the factory site.

At 9.15 a.m., as usual, we had a meeting with the operators.

At 10.00 a.m., I was planning to observe the DPRS, however it was raining heavily. I stayed in the office to update the Maintenance Plan using an Excel file. Besides that, I read the technical description manual prepared by the manufacturer. This manual listed the information and explained the function of each equipment installed in DPRS.

Low range turbidimeter (taken on the same day)

At 2.00 p.m., I began to study the operation manual of DPRS prepared by the manufacturer.

At 3.00 p.m., I went to the DPRS site and traced the pipelines from the beginning to double-check whether the information I obtained was correct since there were several parallel piping equipped with the same instruments.

At 4.00 p.m., I updated and checked the Maintenance Plan using an Excel file in the office.

Internship in Nestlé - 15-16th Dec 2016 (8am - 5pm)

Thursday, 15^th Dec 2016 (8am - 5pm)  

At 9.15 a.m., we had a meeting with the operators. We have been informed that recently many production plants have performed shut-down procedures during the end of the year.

At 9.45 a.m., I went to the DPRS installation site to observe the equipment and piping after wearing a safety helmet and reflective vest.  The installation was ongoing and the workers were pouring cement for the construction of the foundation. It was inconvenient for me to walk around safely to study the DPRS system.

At 10.00 a.m., I noticed a piece of metal mesh grate was located at the walkway around the existing DAF unit in WWTP. It was suspected that the metal grate was left after the construction, making a protruding floor surface that was not obvious to be seen. I sent an email to Tee regarding this safety issue.

At 11.15 a.m., Tee gave me the task of preparing a maintenance plan for DPRS. I have to identify which equipment and instruments are required for maintenance and to list their serial numbers by next Thursday, with the aid of the technical description manual received from him. In addition, he also gave me an instrument list and the P&ID of chlorine dioxide generation and dosing system for my reference.

At 2.00 p.m., as usual, I continued to observe the existing fitting and piping of equipment in WWTP and took notes for updating the P&ID drawn using Microsoft Visio.

Then I began to study the information and manual given before preparing the maintenance plan.

Friday, 16^th Dec 2016 (8am - 5pm)

At 9.15 a.m., as usual, we had a routine meeting with the operators.

At 10.00 a.m., it was a short break time for the contractors. I entered the installation site of DPRS to begin my first observation of the DPRS built so far. It is to avoid the site being crowded by people when the installation is continued later. Using the P&ID as a guideline, generally, I managed to trace the flow of DPRS with the fittings along the pipelines. However, some equipment and instruments were pending to be installed.

At 2.00 p.m., I continued the data collecting of DPRS. While observing the flow and piping, I learned the appearance of various types of valves that are commonly used in industrial sites. Then I walked around the existing WWTP to observe the check valves I had missed out so far.

At 3.45 p.m., I started to create a draft of the maintenance plan and typed in the information using Microsoft Excel. Tee had told me to finish the task and there would be further details to be included as well.

Internship in Nestlé - 12-14th Dec 2016 (8am - 5pm)

Monday, 12^th & Tuesday, 13^th Dec 2016 (8am - 5pm)

PUBLIC HOLIDAY

Wednesday, 14^th Dec 2016 (8am - 5pm)

At 9.15 a.m., we had a meeting with the operators as usual. Tee informed us that one operator was cut by the sharp protruded edge of a metal insulation pipe during cleaning. He wanted us to learn from this lesson and advised the operators always to identify and report any hazards in their working areas as soon as possible to prevent any accidents.

At 9.30 a.m., Satiya asked me to bring personnel to collect the water sample from the final discharge point. This is a weekly task conducted by the agent to collect the final discharge sample for monitoring the parameters of discharged water and to be reported to DOE.

At 10.00 a.m., Vasu explained to me the structure and piping of the sludge silo which is located near the WWTP control room. However, there was a leakage of sludge from one of the outlets of the silo. He suspected that one of the gate valves had been accidentally opened. He was water spraying on the floor to remove the overflow sludge.

Later Tee had told me that I am allowed to enter the installation site of DPRS from today onwards to trace the piping and flows. However, a safety helmet and reflective vest must be worn at all times when entering the site. He then gave me a reflective vest.

At 11.30 a.m., I went back to the office and updated the P&ID of WWTP based on the data obtained just now.

At 2.45 p.m. onwards, a mechanic was repairing the surface skimmer of the second clarifier as the blade was bent and hit with a scum baffle. The rotating skimmer was stopped and locked using a lockout & tag-out (LOTO) device to avoid any accident in case of unintentionally switching on the machine. 

Internship in Nestlé - 8-9th Dec 2016 (8am - 5pm)

Thursday, 8^th Dec 2016 (8am - 5pm)

At 9.15 a.m., we had a short meeting with the operators. The meeting agenda is the safety aspect, followed by any highlights.

At 10.00 a.m., Jaclyn shared the operation manual of the existing RO plant for producing treated water for the boiler. I read it to understand the operation of the RO process.

At 1.45 p.m., I continued to complete the WWTP flow diagram using Microsoft Visio.

At 2.45 p.m., the administrative assistant, Ms. Yvonne informed me that my own company account was ready to use finally. From now onwards I can access the company computer using my account and communicate with others using the given company email address.

At 4.45 p.m., Tee listened to my presentation about my understanding of WWTP on the site. Tee gave me feedback that there are several additional details I should explore and understand by myself. Then he lent me a book titled Self Regulation Approach – Certified Environmental Professionals in IETS Operation (CePIETSO) – Biological Processes.

Friday, 9^th Dec 2016 (8am - 5pm)

At 8.30 a.m., I started to read the book CePIETSO (Biological Processes). This book is published by the Environmental Institute of Malaysia (EiMAS). It contains plenty of information and regulations relating to industrial effluent treatment systems (IETS).

At 9.15 a.m., we had a short meeting with the operators. Before the end of the meeting, Tee introduced a new colleague, Shanji to us. He will mainly be in charge of environmental aspects, including WWTP.

At 3.00 p.m., I walked around WWTP with Vasu to observe the flow and piping in WWTP. Vasu was using water to spray on the floor in the DAP area because there was acid leakage from the chemical dosing system.

At 3.45 p.m., I also studied the details of the main influent and effluent from this DAF unit. The influent is from the DAF balance tank and the effluent of DAF is pumped to the aeration tank for further processes. 

Internship in Nestlé - 7th Dec 2016 (8am - 5pm)

At 9.15 a.m., we had a routine meeting with the operators. Tee had told us there was a minor accident in the cereal production plant last Saturday. He reminded us to always ensure safety when working in the plant.

Then Tee asked me to help him generate the details of the chiller cooling towers in softcopy. I keyed in the information using Microsoft Excel and submitted the file to him via e-mail.

At 11 a.m., I began to summarize all information and drawings of WWTP for tomorrow's presentation to Tee. Jaclyn had given me several additional information and Power Point slides relating to WWTP.

At 12 a.m., I noticed that the DAF unit was not in operation. This is due to the low level of the DAF balance tank, leading to low incoming flow into the DAF unit. Therefore the DAF unit was temporarily shut down by the operator.

At 3 p.m., I went to the WWTP control room and was informed that the low-level (LL) sensor in the raw pit was not functioning and caused the submersible pump to shut off. The operators replaced a new LL sensor and switched on the pump to return to normal operation.

At 4.15 p.m., Vasu had given a brief explanation to me while observing the equipment in WWTP. The information was about the sludge silo, recirculation pit, clarifiers, outlet from the aeration tank to clarifiers and final discharge point. 

Internship in Nestlé - 6th Dec 2016 (8am - 5pm)

At 9.15 a.m., as usual, we had a meeting with the operators. The operators were highlighting any updates of each service section.

At 9.40 a.m., Vasu was with someone at the final discharge sampling point, which is near to the WWTP control room. He told me that every early of month an officer from an agency will come to collect the water samples from several sampling points such as final discharge, aeration tank, balance (equalization) tank, DAF influent and effluent. The officer will analyse the water parameter and report to the Department of Environment (DOE) Malaysia to monitor the quality of discharged water from the industry.

Final discharge point

At 10.30 a.m., I followed Vasu to DAF. I observed the pipelines around the existing DAF unit. He monitored the water condition and adjusted the chemical dosing. Later he explained to me the air saturation unit of DAF. The purpose of air saturation is to produce the raising of suspended solids onto water surfaces in the form of scum by aeration and chemicals, followed by removal of scum by skimming.

While observing the air tubing, suddenly there was a water droplet dropped into my eye. Vasu brought me to wash my eyes using clean water at the washing station. It is suspected there is a leakage around the old DAF unit.

At 1.45 p.m., I continued data gathering and this time observing the chemical dosing systems of the DAF unit. Vasu told me that three types of chemicals are used in dosing systems, which are FeCl₃, sulfuric acid and polymers for coagulation and flocculation processes. He also guided me to observe the pipelines, connections and fittings of chemical dosing systems.

At 3.30 p.m., I drew the P&ID for the existing DAF unit using Microsoft Visio based on the information I collected today.

At 4.30 p.m., Jaclyn showed me the operational manual of DPRS consisting of a membrane bioreactor (MBR) and reverse osmosis (RO) system. She told me that recently we have been focusing on this project since the installation of DPRS is ongoing. 

Internship in Nestlé - 5th Dec 2016 (8am - 5pm)

At 9.15 a.m., we had a routine meeting with the operators from the boiler, chiller and WWTP. The purpose of the meeting is to update information and ensure the plant is always operated under normal and safe conditions.

At 9.45 a.m., I went to the WWTP control room and Desa was on shift. After having a quick conversation with him, however, I realized he did not know much about WWTP in detail, so I did observation around the WWTP to continue data collecting.

At 11.00 a.m., I began to sketch the PFD of WWTP using Microsoft Visio.

At 3.00 p.m., finally the boiler chargehand, Satiya gave me a brief explanation about WWTP. He said that to understand the operation and flows of WWTP, first and foremost, we have to understand the fundamental knowledge relating to WWTP. The purpose of constructing WWTP is to meet the environmental limits of final discharge for sustainability and the future.

There are primary and secondary treatments or biological and chemical methods in our plant. The biological method utilises bacteria whereas the chemical method uses chemical dosing for water treatment. I understood what he explained to me easily because I had studied water treatment for my group design project during the past study semester. 

Internship in Nestlé - 1st & 2nd Dec 2016 (8am - 5pm)

Thursday, 1^st Dec 2016 (8am - 5pm)

At 8.30 a.m., I met another on-duty WWTP operator, Desa. He explained that the laboratory experiments are conducted three times each day and all parameters of water sample would be recorded. Again I observed the structure of DAF which is under operation.

At 9.15 a.m., there was no routine meeting.

Almost all colleagues of the Engineering department are participating in the 2D1N team-building activity. Only Bhajan, Lok and I were in the office.

I was studying and understanding the PFD and P&ID of DPRS given by Tee yesterday in the office.           

Friday, 2^nd Dec 2016 (8am - 5pm)

At 9.15 a.m., there was no routine meeting.

Based on the data gathered and observations during the past two weeks, I sketched a PFD of existing WWTP as a draft on A3 papers. This would give me a rough idea and picture of the whole WWTP.

The diagram of new expanding or upgrading systems in WWTP such as DPRS and new DAF to be installed will be drawn in the following time.

At 12.30 p.m., I joined Bhajan and Lok to have lunch during these two days. They shared their work experiences to me who is a junior. Lok shared his opinion about the purpose of encouraging energy saving in Nestlé. He said that it would be a significant amount of cost savings by considering the various aspects for large food production plants such as Nestlé

At 3.00 p.m., I continued studying the P&ID of DPRS in the office. I tried to understand the detailed information provided in the P&ID of DPRS, such as mass balances of inputs and outputs, pipelines, fittings, structures, symbols of equipment and instrumentation, etc.                

Internship in Nestlé - Wednesday, 30th Nov 2016 (8am - 5pm)

 Wednesday, 30^th Nov 2016 (8am - 5pm)

At 9.15 a.m., we had a routine meeting with operators for any updates of each service section. I informed Tee about the tasks I had done in the past two days and asked him for any tasks for this week.

At 10.00 a.m., I met a chillerman, Shahwal in the WWTP control room. He told me that each operator should understand all utility services such as boiler, chiller, WWTP, etc. although one is assigned to only certain service.

At 1.45 p.m., I walked around the WWTP to gather much information about the overall WWTP. Recently there have been several ongoing constructions for upgrading WWTP. I observed that the new equipment with pipelines, fittings and pumps are stored in either metal containers or plastic covers for installation of the direct portable reuse system (DPRS), a sophisticated system to be introduced and operated in WWTP in the future.

At 4.45 p.m., Tee gave me the latest process flow diagram (PFD) and P&ID drawings of DPRS, generated by the manufacturer, for my own reference.

Internship in Nestlé - 28-29th Nov 2016

Monday, 28^th Nov 2016 (8am - 5pm)

At 9.15 a.m., there was no meeting as my coach, Tee was attending a training course during these two days.

At 10.00 a.m., I explained to Ridzuan my task of redrawing the WWTP process diagram so I wished to study each equipment in detail. Then I followed him to the first equipment in WWTP, a raw pit. He opened the manhole and shared the knowledge relating raw pit, such as the incoming water sources, pipings and fittings.

At 11.15 a.m., he received a call from a boiler chargehand, Satiya, to ask me to come to his office. Mr Satiya asked me to help him type out the SOP for the loading and unloading of diesel and LPG cylinders.

At 2.00 pm, I continued to study the information about raw pit under the guidance of Ridzuan. The raw pit is used to collect all influent sources before pumping to the balance tank. I recorded all the details explained by him in my notebook.

At 4.00 p.m., I went back to the office and sketched the raw pit based on the information obtained. 

Tuesday, 29^th Nov 2016 (8am - 5pm)

At 9.15 a.m., there was no meeting.

At 10.00 a.m., Ridzuan and I went to the existing DAF equipment. He was adding the polymer in the dosing tank while monitoring to ensure sufficient dosing for flocculation to occur in DAF. At the same time, I observed the chemical dosing system of DAF which is under operation. Then for certain doubts, I asked him for further information.

Polyacrylamide, used a flocculant in wastewater treatment

At 11.45 a.m., I was asked by Satiya to assist him in completing the piping and instrumentation diagram (P&ID) of updating the air compressor system in the Beverage Mixed plant using Microsoft Visio. I took this opportunity to study the P&ID drawing prepared in real industry.

At 1.30 p.m., I continued to finish the P&ID before sending it to Satiya for checking. He also explained the information and meaning of symbols used in P&ID.

Internship in Nestlé - 24-25th Nov 2016 (8am - 5pm)

Thursday, 24^th Nov 2016 (8am - 5pm)

At 8 a.m., I met my colleague, Jaclyn Yee in the office. She had been working in this department for four months.

At 9.15am I followed Jaclyn to attend the routine meeting in the boiler control room. In this room, various performance graphs of power consumption are displayed on the wall. The on-duty operators from each section were gathered and reported the feedback to Tee. The meeting lasted 10 minutes.

At 10.00 a.m., I went to the WWTP control room and met the on-duty operator, Mr. Vasu. He shared the process flow chart of existing WWTP and explained each process. Suddenly one alarm was triggered and he pressed a button to switch off the alarm. He told me there was a case when there was a high level in the balance tank due to incoming industrial effluent from the production plant, however, it was considerably accepted.

At 3 p.m., I went to the control room again. This time Mr. Ridzuan was on duty. He had shared his knowledge about the WWTP operation. I took this opportunity to understand the daily tasks carried out by the WWTP operators.

Friday, 25^th Nov 2016 (8am - 5pm)

At 9.15 a.m., I attended the routine meeting in the boiler control room. Before the meeting, there is a tradition of making a swear, ‘Safety begins with me’ by all attendees. As usual, the on-duty operators from each section gave feedback to Tee. The meeting lasted 10 minutes.

At 3 p.m., Ridzuan brought me around WWTP while collecting the samples from the final discharge point, DAF inlet and outlet, etc. Next, he conducted the laboratory test using these samples to check the water characteristics such as pH, colour and chemical oxygen demand (COD), etc.

I was taking this opportunity to observe the procedure of testing samples. He willingly explained the details of these procedures. He explained that these are routine tasks to be carried out by operators and several water parameters must be recorded for further reference.

Internship in Nestlé - Wednesday, 23rd Nov 2016 (8am - 5pm)

At 8 a.m., we gathered in the HR meeting room before we were sent to our respective departments and met our training supervisor/coach.

At 9 a.m., we took the anti-typhoid vaccination at the factory clinic for health and hygiene purposes.

At 10 a.m., three of us including me followed Ms Jiwana to the Engineering department. In the office, we had a short meeting with our manager of the Engineering department, Mr Shinya Nakagawa. He welcomed us and gave us some pieces of advice.

I was arranged to have my three-month internship in the General Service section. My supervisor is Tee Chee Sin and he is a General Service Engineer. He is mainly in charge of all utility services of the whole plant. He had assigned and briefly explained the tasks I should complete during my internship period (See Appendix A). He advised me to communicate effectively with operators throughout this period to assist me in completing the tasks successfully.

At 11 a.m., I followed Tee to the utility site. He briefly explained to me the existing utility services in the plant such as steam boilers, chillers and industrial wastewater treatment plant (WWTP) in the plant.

Then he gave me an operation manual of the existing dissolved air flotation (DAF) system and assigned me to understand all the information about the DAF system. He told me that recently there would be new equipment to be installed in WWTP. He assigned me to be involved in this project and to prepare the standard operating procedure (SOP) for the start-up of the new DAF during commissioning.

A safety helmet must be worn since there is ongoing construction in WWTP.

At 2.30 p.m., I followed Tee to visit the coffee ground processing plant. Again he emphasized prioritizing the safety aspect of the site. The process of handling coffee grounds involves equipment such as furnaces, hoppers, etc.

At 3 p.m., we went to the WWTP control room and Tee was doing routine log book checking. At the same time Mr Ridzuan, a WWTP operator shared his experience working in WWTP.

Place where I learnt most during internship period

First day of My Internship Period

Tuesday, 22^nd Nov 2016 (8am - 5pm)

At 7.30 a.m., I arrived at the main gate and registered myself at the security office. In the following working days, we should report ourselves here before entering the plant.

An officer from the Human Resources (HR) department, Ms Jiwana briefly introduced today’s schedule in S.H.E (Safety, Health and Environment) meeting room. Then we collected a pair of safety shoes. Wearing safety shoes is mandatory during the working hours.

At 10 a.m., Mr Izwan bin Zainal, senior S.H.E. officer, gave a detailed presentation about the safety aspect in the Nestlé manufacturing factory. He emphasized that the safety issue is always the first priority for us as the employees when in the factory. He shared his experience with the aid of video, statistics and cases that he dealt with during his career life.

At 11.30 a.m., we attended a course about the master plan of Nestlé in the future. It is totally new for trainees to understand the concepts, however, I took the opportunity to understand the benefits and opportunities given by Nestlé to its employees.

At 2.00 p.m., we attended the training session relating to hygiene issues by Mr Lee Heng Hooi, HR executive. He mentioned that hygiene is an important concern for the food industry and the employees are strictly required to follow the rules and regulations when involved the food processing. Employees are not allowed to bring the uniform back home and the laundry services are provided. Then we had a simple visit of the whole plant led by him.

Before the end of the day, we were required to sit for a short test about safety and hygiene to pass the requirements before working.

邂逅

7月11日上午9时，如往常般，我起身就玩手机刷脸书。这时，我收到来自她的问候。这是个阔别近半年以来，她主动邀我见面。我感到惊讶，毕竟半年前闹别扭，随着她的离开，我们好久不再联络了。当时我没马上回复她的信息，心想：还是过一会吧。

当天是个忙碌的日子。上学期成绩公布了，我应好兄弟 Eng Kein 见面。我俩近一个月不曾见面，各自有自己的生活，一见面有说不完的话。他知道今早的事，并告诉我要好好回复她。当中他告诉我，认为我心中依然有她，并且认为我们其实是很配在一起的。我笑笑以对，说明我和她是朋友关系。当时我回复了她的信息，过了些时候她很快就信息我了，还约我一起看电影。奇怪，很不像平时的她拖时间才回复信息。我想：也许是她邀我所以不好意思怠慢吧。直到我回家，我们才定好日期和行程见面。我们谈话得很愉快，过去的矛盾抛开了。我当下心情很兴奋。

这天终于来了。7月13日星期三早上10时，我收到她的信息，说无法陪我看电影了，因为她爸爸要早回。我很失落，不过我们依然可以见面。上午11时，她终于来到约定的地方——校园，我带她四处走走看看校园的小改变。我们来到新图书馆区，新食肆。我们也经过正在装修的tutorial room。她感慨为何她一离开校园才逐渐装修好看。一会我们便离开。

大约12时，我们来到咖啡厅吃早午茶。美食来了，她也不忘拿起相机拍照，还要我做简单pose拍美食。她说：在墨尔本她很少这么做了，因为周遭的环境她不敢这么做，看起来很突兀。她也说：其实墨尔本算是走遍了，最后她还是想回来马来西亚。她依然记得之前我在暑假忙碌的活动，关心地问我ChemeCar比赛成绩如何。我展示给她看影片，却忘了给她看我得奖的画面。谈话中，聊到她在墨尔本的生活，我们的近况，人际关系，课业烦恼。我们互相聆听，互相倾诉。她说：“你是JY以外我告诉心事诉苦的对象。"

接着我们来到Sunway Pyramid逛街。其实是我陪她买东西，她想买生日礼物给她的朋友和JY。我说我也一起出吧。她说：希望我们A level朋友的生日一起庆祝。我听在耳里，铭记于心。她买了很多用品，很多次我想帮她提东西都被她拒绝。我想是用错方式吧，还是我们还不至于某种程度上的关系吧。

然后，我们来到caffebene 吃冰甜品。在宁静的环境，我们再次深入聊天。

这时的我问了她：“可否问妳，妳是愿意谈往事，还是说过去的事不提了？”

她说没关系。我说出了心里纳闷的疑问：“妳为什么今天约我出来？”

她说：“as promised。”

我笑说：“原来那个约定是没有限期的啊。” 她笑说是的。哈哈，也对。回想起当初我还真没规定限期。

接着的谈话，我们谈清楚当时无法在信息中正确传递的想法。我向她道歉，说：“我不是为自己找借口，不过也许同龄朋友，男生永远都比女生幼稚吧。之前我不该执着我们的误会……” 最后，我告诉她：“比起之前，我渐渐学习不再执着任何事物了。” 最后，误会冰释了。

当中我们也谈感情。我问她怎么到现在还没找到对象，她说没有platform，再加上本身有点保守，不像她的闺蜜开放可以去夜店的个性；我和她有同感。我问她心中理想的对象，起初她说没有特定的要求，后来在我的追问之下，她说：“成熟稳重的男人。”

接近下午5时，我们的约会结束了。离开Sunway Pyramid的手扶梯上，我对她说：很感谢妳依然当我是朋友。然后我送她在她爸爸工作地点下车，目送她离去。回家的路上顿时下起雨来。

到了家，我打了很长的信息给了她，对她坦诚之前对她做过的不成熟举动。虽然我知道告诉她简直就在给今天的约会扫兴，并且印象扣分，不过我还是选择告诉她。我也后悔，忘了为今天的邂逅来个合照。

记得好兄弟汨茜对我说过：无法在一起就好好地守护着她吧。我想：我和妳之间之前发生很多事，难得误会冰释了。直到遇到下一个适合的对象之前，我会好好地守护着妳。在妳难过找我聊天，当妳的聆听对象；需要帮忙时，能力范围内一定伸出援手。虽然，妳不一定会找我，妳也有很要好的朋友以及闺蜜。虽然，妳个性很坚强。

希望我们友谊永存。=D
