Abstract

The flocculation of activated sludge is an active process and depends upon physical, chemical and biological factors. The basis of activated sludge floe formation lies in the abilities of micro-organisms to stick to each other and to nonbiological particles. Flocculation is an important phenomenon in the sludge process. Well flocculated sludge settles better, is easier to dewater and leads to a better quality effluent than poorly flocculated sludge. This paper deals with the mechanisms of flocculation, parameters that affect on flocculation and improvement of flocculation.
