Industrial wastewater treatment using Spirodela polyrhiza

Author(s): Vibha Yadav, B Mehra and Abhishek James
Abstract: Industrial wastewater treatment can be done by using Spirodela polyrhiza in different retention time. This study investigates the use of Spirodela polyrhiza improves the quality of industrial wastewater parameters like negative log of hydrogen ion concentration (PH), Electrical Conductivity (EC), Chemical oxygen demand (COD), Total hardness, sulphates, Total dissolve solids (T.D.S.). This study also signifies the Spirodela polyrhiza can be used for accumulation of toxic metals. It was found that after 60 days retention time the reduced level of pH was 7. At initial, maximum chloride content was 214.93 mg/l however the minimum Chloride content after treatment was 173.70 mg/l. Value of total hardness present in water before treatment was 1603 mg/l however the minimum hardness after treatment was 968mg/l. Maximum COD at initial time was 202.66 mg/l however the minimum COD after retention time was found as 64mg/l. Amount of Chromium (VI) before introducing macrophyte was 0.0401 mg/l however the minimum Chromium (VI) after introducing macrophyte was 0.0233mg/l. Minimum chromium (VI) content in plant was 4.92 mg/l however the maximum chromium (VI) content in plant at after 60 days was 7.05 mg/l due to absorption of toxic metals. Minimum copper (II) content in plant was 24.22 mg/l however after absorption of copper by macrophyte the maximum copper (II) content in plant was found as 27.81 mg/l.
