Abstract

Recycling of waste water by ion-exchange was studied on a bench scale. Secondary municipal effluent, which had undergone lime flocculation, served as a feed for the ion-exchange system. It was found that both the salt concentration and the organic matter content of the effluent could be reduced to produce high quality water, suitable for a wide range of agricultural and industrial applications. Salt concentrations was reduced from 15 meq/l (750 ppm as CaCO³) to about 1 meq/l (50 ppm as CaCO³) and the organic matter, from 70-100 mg/l COD (chemical oxygen demand) to 20 mg/l. The anion exchanger was regenerated with Ca(OH)₂ according to a new method recently developed. The treatment cost for a 2000 m³/day plant was calculated to be 18.0 ¢/m³.
