The goal is to reduce the oxygen requirement. You have been called in as an expert to give a qualitative assessment of this plan. a. Will the oxygen requirement actually be reduced? b. Will the MLVSS increase, decrease or stay about the same? c. Will the sludge settling characteristics improve, stay about the same, or worsen? d. Will the effluent BOD concentration increase, decrease, or stay about the same? 3. Filamentous bacteria that cause sludge foaming in activated sludge treatment systems differ from the desirable floc-forming bacteria in several aspects of their metabolism.
