At 9.15 a.m., we had a daily review meeting with the operators.
At 11.00 a.m., I met Jaclyn and WWTP operator, Ridzuan at the existing DAF unit while they were monitoring water condition in the flocculator. The flocs were unable to be produced after several sample tests.
At 2.30 p.m., I went to WWTP and observed the unit operations. I noticed that due to the outlet is constructed at a higher point, the final discharge was full of water before entering the pump pit, which is the first section of DPRS. Later I met Christ, my colleague who is in charge of electrical service and he wished to understand the process flow of DPRS. I took this opportunity to revise the DPRS study by explaining the process description and answering his questions about the DPRS. He thanked me for guiding him to understand DPRS within a short period.
At 3.15 p.m., I had a great chat with a safety personnel, Hazi. He is in charge of monitoring the construction safety.
At 3.30 p.m., Jaclyn and I observed the pipeline around the permeate tank, which is the final section of DPRS for clean water distribution. The pipeline arrangement is totally different from that shown in P&ID. We had redrawn the diagram for our own reference. Later, we went up to the top of the permeate tank to trace the source of the pipeline. I managed to observe and recognize several fittings such as air vent pipes, water pressure relief valves, pressure regulators, etc.

At 4.50 p.m., we studied the chlorine dioxide generation and
dosing system at the DPRS site. However, we did not really understand how it
works, and perhaps guidance may be given by the technician in the future.
