Abstract |
The feasibility to demonstrate pretreatment of packinghouse wastewaters was investigated in the laboratory. The pretreatment consisted of a Kehr activated sludge process in conjunction with in-sewer treatment. Laboratory tests were designed to study the oxygen uptake, contact time, potential foaming and scum problems, flow characteristics, odors, BOD removal efficiency, clarification, and return of activated sludge of high suspended solids mixed liquor reactors using packinghouse wastes. Sampling and analysis of the sewer flow and gases generated, along with work on in-sewer treatment and corrosion protection were evaluated as part of the pretreatment process. |
