A study was completed which compared chlorination of field potable water with aqueous CaOCl2 metered with chemical feeding pumps and NaOCl or chlorine generated on-site using the more readily available table salt as the source. A parallel effort was completed defining the chemical reactions involved in the generation of NaOCl and those involved in treating potable and waste waters, including the reaction of various inorganic and organic chlorine forms with dissolved organics. Current Army chlorination practices were investigated. Evaluation of the state-of-the-art of all types of on-site hypochlorinators was accomplished by surveying industrial manufacturers of this equipment. Design data was developed for an on-site hypochlorite generator sized to meet current military needs. A comparison methodology was selected and criteria for comparing mechanical feeders and on-site generators were made. Major comparison criteria included maintainabilityreliability, ease of operation, performance, size and weight. It was concluded that both processes would be satisfactory for field application.
