7.0 Procedure:
7.1 Precautions: All maintenance activities must be done safely in accordance with the necessities of the Plant Safety Declaration and the safety notices from place to place the plant. Specific consideration must be paid to the following:
- Handle the chemicals by wearing PPE.
- Ensure that the pumps are switched off before initiating any kind of maintenance.
7.2 System Description:
The capacity of ETP is 5000 Liter/hour. The effluents from the production department come into the neutralization and equalization tanks via bar screen chambers. In this bar screen chamber the floating material/solid material is being filtered. A dosing of lime is being delivered in the neutralization tank if pH correction is needed.
The effluents are aerated in this tanks with air which is delivered by the blowers. After being neutralized in the neutralization tank the effluents goes into the equalization tank & then the effluent is relocated to the flocculation tank through effluent transfer pumping system.
A dosing of PAC [Poly Aluminum Chloride] is delivered in the flocculation tank to flocculate all the effluents. Poly electrolyte dosing [PED] is delivered in the transferring pipe of effluents from flocculation tank to the lamella.
After lamella the effluent is passed to the aeration tank. In aeration tank the effluents are aerated with air. A dosing of NaOH[Sodium Hydroxide] is provided if it is required.
There is a buffer tank after the aeration tank where 1kg of urea will be delivered after every Two months of operation. There is a line under the buffer tank to transfer the sludge to underground sludge tank & then to sludge pit by sludge transfer pumping system.
Clear water from the Buffer Tank is stored in the clear water tank. There are two pumps to transfer the clear water to final storage tank through MGF [Multi Grade Filter] & ACF [Activated Carbon Filter]. One pump is used at a time.
