||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.
||Presented at the Environmental Protection Agency Technology Transfer Program Design Seminar Held at Chicago, Illinois on November 28-30, 1972. See also report dated Aug 72, PB-258 818.
