From 8.00 a.m. to 4.30 p.m., I prepared a detailed SOP for operating the membrane chamber filter press system, based on the script given during the training session. This file consists of three main sections, which are before using the filter press, using the filter press (manual and automatic mode) and discharging the sludge cake.
At 9.15 a.m., we had a daily review meeting with the operators.
Between 10.00 and 11.45 a.m., Jaclyn and I met Chow at the filter press site. Chow continued to conduct testing on filter press operation. During the operation, we observed the residual water was flowing into the raw pit. Eventually, the final product, sludge cake was drier than previous testing. I had taken several photos which to be inserted into the SOP file.
At 4.30 p.m., we had a meeting in the DPRS control room. They confirmed that a training session would be provided to us and the WWTP operators next Monday and Tuesday. Hence, I must be on the DPRS site from next Monday morning.
Besides that, we discussed the issues of clean water drainage and chemicals to be used during the MBR commissioning. Next, Istiak discussed with us the issue of sodium hydroxide (NaOH) usage for the new DAF operation. Later Tee and Fam went to the existing DAF site and discussed the issue of supplying NaOH while observing the existing NaOH tank there.
At 5.30 pm., I sent the detailed SOP of the operating filter press system to Tee.
