Abstract |
High amounts of Ammonical Nitrogen is one of the major factors that pose problem during the treatment of Industrial Wastewaters. The goal of reducing the values of (NH4+N) well within the legal discharge standards is not only a difficult job, but can also become expensive if process optimization is not performed correctly. In this particular study, the effluent was obtained from a major agrochemical company in India, whose (NH4+N) content lingered around (180 to 250) ppm. Presently, Sodium hypochlorite dosing is administered to lower down the Ammonical Nitrogen, but due to the fact that this process is not an eco-friendly one, the search for a better process having more advantages over Hypochlorite treatment led to option of Electrochemical Oxidation process. The aim of this study is to analyse the applicability and efficiency of (Electrochemical Oxidation) process to lower the Ammonical Nitrogen concentration below 50ppm. Electrode material remained same during the experiment whereas the values of voltage, pH were optimized. Five values of voltage and five values of pH were fixed for the study. We saw a 98% reduction in the Ammonical nitrogen content within a time period of (180 minutes), which upon power and cost calculation, also proved to be cheaper than the Hypochlorite treatment that was originally followed by the Industry. |
