NONBIOLOGICAL REMOVAL OF ORGANIC POLLUTAN TS FROM WATER

Contaminants present in waste water, seepage water and ground water in clude salts, heavy metals and organic compounds of low biodegradabilit y. This paper considers the wide range of physico-chemical processes a vailable for separation of such compounds from water and points out th eir optimal and economic range of application. Main subjects are desor ption processes (air/steam stripping), adsorption processes (activated carbon, polymeric resins) and membrane separation processes. Alternat ive water treatment technologies (evaporation, distillation, liquid-li quid-extraction, oxidation, flocculation and precipitation) and combin ed processes are presented and discussed.
