Abstract The case histories described in this report relate to upgrading the performance of activated sludge and trickling filter plants through modification to the biological processes. In these processes the biochemical reaction rates depend on the concentration of reactants (wastes) and of the appropriate microorganisms capable of feeding on the wastes.
