Abstract
Heedless growth of global population, environment change, and collapsing water framework have all surged for a better water treatment system. Electrochemical technologies have a brighter perspective in this requisite over established water treatment technologies, as they have numerous advantages such as high efficiency, safety, ease of operation, flexibility, and cost-effectiveness. Therefore, the present study envisages nitrate removal from groundwater using the electrochemical technique (electrocoagulation (EC)). The effect of the presence of electrolyte (NaCl and Na2SO4) concentration, on current flow, electrolysis, pH of the solution, energy, and operating cost on the nitrate’s removal efficiency were assessed. It was observed that NaCl has positive effects on nitrate removal as compared to Na2SO4.
