Abstract
Foaming and bulking in secondary mixed liquor particularly in activated sludge waste water treatment plants is a growing problem. The efficiency of secondary waste water treatment is critically dependent on the separation of the supernatant liquids from the sludge. Bulking and foaming primarily make it very difficult or impossible to achieve effective separation, thus reducing the treatment efficiency. The study is part of an ongoing effort by practitioners to understand and quantify the extent of the problems of foaming and bulking. The study presents a survey of some waste water plants in the northwest United States, and the results of statistical analysis in search of linkages between operating characteristics and settling problems.
