Natural Adsorbents for Agricultural Waste Water Treatment

In now a days, water problems have been one of the focus of great international concern and debate. Environmental pollution is mainly due to rapid industrialization. It is a demanding problem for maintaining the quality and cleanness of water. The discharges of industrial wastes in to aquatic bodies are a great threat to the aquatic life as well as for human health also. It is a matter of great importance due to their toxicity and after effects. Adsorption is an ecofriendly technique used now a days to treat the agricultural waste water. The sewage water is firstly filtered through suitable low cost and ecofriendly filter medias. Then the filtered water is subjected to adsorption using low cost and easily available natural adsorbents like banana peels and M. Thilapia fish scales. The combination of both these adsorbents was used for treatment of waste water with different proportion of height and contact time. The treated water obtained will have a considerable decrease in TDS, bacterial count, nitrogen content, Iron content, Potassium, TSS, turbidity, phosphorous, etc. as compared to initial characteristics of agro wastewater. This method is highly economic, cost effective and eco-friendly. This helps in reducing the water scarcity with the use of low cost adsorbents .
