Internship in Nestlé - 6-7th Feb 2017 (8am - 5pm)

Monday, 6^th Feb 2017 (8am - 5pm)

At 8.30 a.m., I emailed the punch list of WWTP, which was created last week, to Tee after including all the issues.

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

Between 9.30 a.m. and 5.00 p.m., I continued to prepare the SOP of the new DAF system. I had taken several photos of the PLC panel and the instruments of the new DAF system, which would be included in this SOP.

At 11.00 a.m., Jaclyn and I were in the DPRS control room and we noticed that the scheduled 10 a.m. maintenance cleaning (MC) of MBR was aborted. This situation occurred since last week, however the PLC panel just displayed ‘ABORTED’ without any detail. We had informed the project engineer, Fam about this issue.

At 3.00 p.m., Fam, Jaclyn, Christ and I were in the DPRS control room. We had communicated with Maurice online about this issue and required technical support to fix this problem. We exchanged the MC schedule of both MBRs to investigate this issue further.

Tuesday, 7^th Feb 2017 (8am - 5pm)

Between 8.30 a.m. and 12.00 p.m., I updated the Spare Part List for new DAF and DPRS as requested by Jaclyn and with Fam’s guidance. The information on spare parts such as brand and dimension was recorded for future reference. I emailed these files to Fam once completed and checked.

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

At 9.50 a.m., Fam asked me to help him monitor the operational mode and parameters (mainly TMP) of MBR during the MC at 10 o’clock later. I went to the DPRS control room to monitor the MBR MT5750 which conducted MC for an hour while the other (MT5700) was in production mode. Eventually, the MC was completed before automatically returning to production mode.

Later at 2.00 p.m., again I monitored the MBR MT5700 which the MC was scheduled at this time. I noticed that once this MBR entered MC mode, the PLC panel immediately displayed ‘ABORTED’, without further stages. I returned to the office to inform Fam about this same issue. I typed the collected data of these two MC periods into an Excel file before emailing this file to Fam.

At 3.15 p.m., we communicated with Maurice about this issue online. 

Internship in Nestlé - 1st-3rd Feb 2017 (8am - 5pm)

Wednesday, 1^st Feb 2017 (8am - 5pm)

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

At 11.00 a.m., someone asked me to help him sort the information in his Excel file.

Between 10.00 a.m. and 4.00 p.m., I studied the process flow diagram and P&ID of DAF in the office before performing the pipeline tracing of the new DAF unit which is under operation now. Meanwhile, I took several photos of the tag number of the pump and instruments for FLOC registration of the new DAF unit. Currently, the old DAF unit is shut down and the operators were draining off the remaining content before cleaning the old DAF unit.

Thursday, 2^nd Feb 2017 (8am - 5pm)   

At 9.15 a.m., we had a meeting with the operators. The WWTP operator, Ridzuan had brought out some issues about the operation of the new DAF unit, such as leakage at several parts. Shanji had asked me to follow up on these issues.

At 9.30 a.m., I followed Ridzuan to observe the sections where he mentioned during the meeting. He said there was leakage at the flange of the automatic valve located between the DAF feed pump and flocculator due to a sudden surge during the start-up of the system. Besides that, there is leakage from the sludge discharge compartment. I have taken photos of the sections for reference.

Later Shanji shared with me the template of the Punch List for WWTP. He explained that this list is used to record the issues reflected by the operators in their working areas. Shanji and I generated the list based on the issues reported by the operator.

Friday, 3^rd Feb 2017 (8am - 5pm)

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

Between 10.00 a.m. and 4.30 p.m., I completed the FLOC registration of the new DAF system, including the details of the maintenance required. Jaclyn and I monitored the operation of DPRS, especially the parameter (TMP) before and after the scheduled maintenance cleaning of membrane modules in both tanks. Meanwhile, I have begun the SOP of the new DAF unit based on the information recorded last week and the operation manual of the new DAF.
