PROCESS OF WASTEWATER TREATMENT PLANT : Wastewater enters the treatment plant First it goes through a fine screen, next to aerated grit chamber, and then enters the primary clarifier. Sludge settled in the primary clarifier is sent to the fermenters and then to digesters. After the primary treatment, wastewater flows into (BNR) bioreactors. The activated sludge is separated in the following secondary clarifier. The clear effluent flows into Ultraviolet (UV), then to River. Settled activated sludge in the secondary clarifier is pumped back to BNR. Excess sludge is pumped into the dissolved air floatation (DAF) unit for thickening. Wastewater is collected in sanitary sewers (a complex network of underground pipes). Upon reaching the treatment plant, the wastewater flows through a series of treatment processes which remove the wastes from the...
