Phytoremediation of effluent textile wwtp for nh3-n and cu reduction using pistia stratiotes

Abstract

Quality of typical conventional treated textile wastewater treatment plant (WWTP) become environmental problem because of high levels of nutrients and metals. Nutrients and metals regulated in the quality standard are NH3-N and Cu. This study aims to determine the phytoremediation process of Pistia stratiotes to NH 3-N and Cu removal. The steps of the research were conducting range finding and running test. The range finding test, effluent textile WWTP concentration was 20%; 40%; 60%; and 80%. In the range finding test process for 21 days the number of dead Pistia straiotes was 0%; 4%; 12%; and 16% of the total test biota were 25. In the running test with 100% effluent textile WWTP, NH 3-N and Cu removal are 71.25%±5.8 and 76.7%±9, respectively.
