Abstract This research has been conducted (1) to determine how destabilizing chemicals function in enhancing the effectiveness of filtration processes, and (2) to consider selected applications of destabilizing chemicals in filtration for the treatment of wastewaters. The investigations have included (1) laboratory experiments using polymers and latex suspensions, (2) laboratory and pilot plant experiments using alum, polymers, and trickling filter effluent, and (3) laboratory experiments using polymers and calcium phosphate suspensions. The report includes conclusions regarding the mechanisms of polymer action in filtration, the results that can be obtained using polymers as filter-aids, and the application of this knowledge to the design of filtration processes for wastewater treatment.
