Use of Root Zone Technology for Aquatic Life and Organic Farming

Water quality, reuse and recycling is a major challenge in the world now a days. The rapid urbanization has resulted in pollution of fresh water bodies due to increase in the generation of domestic waste, sewage, industrial waste etc. In this treatment process domestic (kitchen waste) waste will be used in fish production than this fish tank water used in root zone treatment and organic farming creation and bath waste also used in root zone treatment plant get filter then and get used for farming. That excesses water should pass through soil layer (double filtrations). Aquaponic is the combined culture of fish and plants in recirculating systems. Nutrients, which are excreted directly by the fish or generated by the microbial breakdown of organic wastes, are absorbed by plants growing in the hydroponic system. Fish feed provides most of the nutrients required for plant growth. As the aquaculture effluent flows through the hydroponic component of the recirculating system, fish waste are removed by nitrification where the excreta is converted to nitrites and nitrates and direct uptake by the plants, thereby treating the water, which flows back to the fish tank for reuse. Some physico-chemical parameter namely dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), nitrate and phosphate were analyzed using standard methods. The treated water from the system can be used for recreational activities like washing clothes, fishing, swimming, irrigation etc.
