At 9.15 a.m., we had a daily review meeting with the operators.
At 9.30 a.m., after the meeting, I went back to the office to prepare the presentation for Mr. Bala’s visit.
At 10.30 a.m., Mr. Bala called me upon his arrival while waiting for me in the security office. I welcomed him and brought him to meet my supervisor, Mr. Tee. We had a discussion in the HR meeting room. First and foremost, I introduced the given tasks to be completed during my three-month internship period. Next, I presented the process flow of DPRS while showing the scribbled P&IDs to Mr. Bala. I had answered any questions asked by him relating to DPRS.
After that, Mr. Bala asked each of us several questions to understand my workplace and current progress from both sides. He also gave several comments for the enhancement of my internship experience. Unfortunately, we did not manage to have a site visit for him due to inconvenience and safety issues as several sections in WWTP are under construction. Lastly, he requested us to fill out a feedback form, individually. Afterward, Tee was busy and left earlier while Mr. Bala had a short conversation with me. He was satisfied with the opportunities received by me and the value of training in my chemical engineering study. He also was particularly interested in the P&IDs I had studied. Eventually, the visit was up to an hour.
At 4.00 p.m., we had a meeting in the DPRS control room to get any feedback from the PIC. We were informed that the ultraviolet (UV) disinfection system is ready for operation. However, Maurice suggested a flowmeter should be installed at the outlet of the UV system, right before the inlet of the RO system. He also required Tee to provide the parameters of treated water for the past four weeks, such as flow rate, COD, pH, etc. Besides that, a DPRS training course is scheduled for us next Thursday.
After the meeting, I followed Tee to get a high-density polyethylene (HDPE) carboy of sodium hypochlorite (NaClO) as requested by PIC. The purpose of using this chemical is to kill the microorganisms present in the fiber membranes before MBR operation. Later I prepared a table consisting of parameters of treated water for the past four weeks before emailing this file to Tee for checking.
