Question 3)
In Waste water treatment plant ( WWTP's) Anaerobic is defined as when there is no oxygen or nitrate species to use, this depicts that there is no electron acceptor. where as anoxic is defined as there is presence of nitrate species to use but there is absence of oxygen. It means in anoxic electron acceptor is nitrate. In aerobic electron acceptor is present and can utilise both oxygen and nitrate.
Question 4)
Activated sludge process is used to treat the waste water in presence of aeration. Activated sludge process include bacteria and protozoan.

Name: ID: 2. The activated sludge process can be used to remove organic carbon (BOD) and nitrogen species (ammonia, nitrite and nitrate) from wastewater. The schematic below is a of the 4-stage Bardenpho process that can achieve low levels of ammonia and nitrate in the final effluent). Please describe how BOD and nitrogen species concentrations evolve in each stage, include what the return activated sludge, the internal mixed liquor return, and the methanol injection are used for. "nitrite does not...
