Hussain, S: Treatment of Landfill Leachate using Rotatory Bi

Concern for environmental protection has increased from a global viewpoint due to the exponential population and civilization growth; accompanied by the rapid generation of municipal and industrial solid waste which creates the most instringent paradox around the world. Sanitary landfills are considered as most indispensable solid waste management strategy for sustainable disposal but such implementation is handicapped by the inherent drawback of landfill leachates .The leachate being extremely toxic in nature are threat for the surrounding soil, groundwater and surface water. Aerobic treatment in the form of attached growth biomass systems is considered effective in removal of organic matter from the leachate. The biological oxidation and biosynthesis of organic matter present in leachate is done by the microorganisms used in the treatment process. The process is effective as compared to the other conventional anaerobic treatment of leachate as along with the organic matter harmful ammonical nitrogen can also be conventionally removed .Among all the technologies available for leachate treatment RBC(Rotatory Biological Contractor ) is the most cost effective and efficient.
