DEVELOPMENT OF LOW COST NATURAL ADSORBENT FOR THE TREATMENT OF WASTE WATER: A REVIEW

At present the environmental pollution is the biggest problem in front of world in recent years, the use of physical and Chemical treatments for the waste water are not economically feasible. Theuse of different Natural Adsorbent as an alternative low cost adsorbent for the treatment of waste water has been extensively studied and compiled, together with their adsorption capacities. The advantages of adsorption over the conventional methods are low operating cost, selectivity for specific metal, short operational time and no chemical sludge. Removing of hazardous waste and heavy metals required the use of effective natural adsorbent materials. Many Natural adsorbent materials have been employed for the treatment of waste water which includes: Moringa Oleifera, Orange Peel, Banana Stem, Teak Leaves, E.crassipes, Neem Powder, Charcoal Powder, Sugarcane Bagasse, and Banana Trunk Fiber etc
