D 1291 - 57 Standard Method of Test for Chlorine Requirement of Industrial Water and Industrial Waste Water

Abstract

(a) This method describes a procedure for determining the quantity of chlorine required to obtain a specific objective in the treatment by chlorination of industrial water, including industrial waste water. (b) This method can be applied to all types of industrial water, including solutions of individual concentrated industrial wastes, and to the combined waste water effluents from an industrial plant. (c) This method is recommended as a means of establishing, prior to possible plant application, the quantity of chlorine required to achieve any of the following objectives: (1) Elimination of pathogens in the water, (2) Destruction or modification of decomposable organic substances so as to reduce the biochemical oxygen demand of the water, (3) Elimination or reduction of taste and odors in the water, (4) Separation of grease in waste water by eliminating the protective colloidal effect of proteins present, and (5) Destruction or modification of substances in the waste water that react directly with oxygen, such as ammonia, cyanates, cyanides, ferrous iron, nitrites, phenol, phosphorus, sulfides, sulfites, thiocyanates, and other oxidizable constituents.
