ABSTRACT:
An improved method for the introduction of chlorine into solids contact clarifiers is disclosed. The method allows treatment of effluent by chlorine but, does not allow chlorine to come into contact with the solids contact zone allowing for better coagulation by the use of water soluble polymers, while regulating microbiological surface growths effectively.
