Treatment of Industrial Wastewaters by Anaerobic Processes — New Developments

Abstract

Many industrial effluents contain organic wastes which contribute to high pollution loading and which may be toxic to the environment. While there are a number of aerobic processes (e.g. activated sludge) used to treat these waste waters, anaerobic processes have some advantages for industrial use. Of particular interest is the Upflow Anaerobic Sludge Blanket Reactor process (UASBR) which utilizes extremely active granular sludge allowing very low residence times at a high organic and hydraulic loading.
