Description of Treatment Process:
The wastewater treatment plant uses what is known as an extended aeration type system. The extended aeration type
system means the inflow is aerated for an extended amount of time usually 24 hours before entering the clarification zones. In
this chamber aerobic bacteria decompose the organic solids in the sewage.
Biological waste treatment is a process which uses microorganisms to consume dissolved organic contaminates in
wastewater and convert them into additional microorganisms. Then these are mixed with incoming mixture of microorganisms
and water is channeled to clarification or settling zone where the solid organic contaminated and microorganisms settle, allowing
the water to be removed through a baffle and weir trough arrangement. The organic contaminate (sludge) that settles by gravity to
the bottom of the settling chamber is pumped back to the head of the aeration chamber for mixing with the incoming waste water.
The water that is removed then goes through a disinfecting process. This process uses a tablet hypochlorite system and
dechlorination system. •
