Bioremediation of Ammonia from Polluted Waste Waters- A Review

Abstract

Global water pollution due to industries became a major concern now. Some industrial facilities generate ordinary domestic sewage that can be treated in municipal sewage systems whereas industries that generate waste waters high in conventional pollutants like ammonia need exclusive treatments for their removal from the effluents before discharging. Ammonia can be removed by means of physical, chemical, biological methods. Out of all the methods, bioremediation appears as a promising tool for ammonia pollution as it is a cost effective and converts ammonia into harmless dinitrogen gas. This paper mainly focuses on bioremediation methods available for the removal of ammonia form the industrial effluents and their drawbacks.
