Abstract

"The effect of sunlight on chlorine residuals in water supplies was investigated to provide original and basic information of value to the water purification field.

Three different water systems were employed: (a) The Simplified Water System, (b) The Ground Water System, and (c) The Surface Water System. The RS Sunlamp provided an appropriate source of ultraviolet radiation. A 10 mg/1 chlorine concentration was used. The pH values of 7 and 10 and the illumination intensities of 145 and 200 foot candles were employed. Iodometric determination of chlorine residuals was the main parameter used.

It was found that the chlorine residuals were effectively destroyed by the ultraviolet portion of the sun spectrum within a short period of time. Larger reductions were observed at the higher pH value of 10. Presence of dissolved and suspended impurities decreased the chlorine removal, as did the increased depths. Better reductions were obtained with the higher illumination intensity"--Abstract.
