Feasibility Study on Wastewater Treatment and Production of Livestock Feed by Azolla Pinnata

Abstract

of water is a major threat we face today. Increased population and industrialization are the common factors that fasten the water pollution rate. Here pollution due to Canteen waste water is taken into account and a solution to it by a modern cheapest method known as phytoremediation is studied here. It is the use of plants to remove pollutants from waste water. This treatment method is ecologically sound, economically viable, and has a low capital cost Here Azolla pinnata plant is used to find the feasibility of phytoremediation over canteen waste water. Parameters like pH, Turbidity, COD, DO and BOD was analyzed before and after treatment. Here experiments are conducted to assess the effectiveness of the phytoremediation technique using Azolla pinnata plant over Canteen waste water. The optimum conditions for better performance of Azolla pinnata in treating waste water is identified.ie, Optimum contact time, and Optimum dilution. The phytoremediation system is also compared with a blank of Canteen waste water. Here blank is set up to study the effect of time on the degradation of contaminants. The amount of production of Azolla pinnata at the end of treatment is taken into account and can be utilized for livestock feed.
