Abstract: The anaerobic digestion process is sometimes subject to process upset and has earned the reputation of being difficult to operate. Knowledge and its processing are limiting factors in achieving effective operation. These ...

Abstract: A dynamic model has been developed for the gas‐liquid interactions of a closed‐tank oxygen system treating carbonaceous wastes. The model describes gas transfer between phases and accounts for equilibrium changes in the ...

Abstract: Traditional set point control and operation of a pumping station using fixed speed pumps usually amplify both the frequency and magnitude of variations in the influent flow rate. The purpose of the present study is to ...
