Chlorine was found to be a very rapid acting disinfectant. Eight milligrams per liter of chlorine decreased the coliform count of wastewater effluents to less than 100 per 100 ml in some cases. Higher doses such as 14 mg per l did not give better results, probably owing to the further disintegration of organic matter. The application of 8 mg per l chlorine to Endamoeba histolytica cysts found in wastewater showed a rapid kill which was temperature dependent. No algal kill was observed within two hours of contact in oxidation pond effluents.
