WebYou have decided to design a CSTR with recycle to degrade TCE (trichloroethylene) cometabolically by aerobic phenol-utilizing bacteria. To do this, you will feed phenol (C 6 H 5 OH; as a C source) and oxygen, along with required nutrients, to the reactor in order to grow a population of bacteria that can fortuitously degrade TCE. The problem is to first … Web3. Circular clarifiers are used to remove solid materials from water. They allow continuous treatment of water and can handle fairly large flows.
