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.
