Abstract

The aim of this work was to investigate the feasibility of the removal of nitrate from water by applying electrochemical methods such as electroreduction and electrocoagulation. In electroreduction, removal of nitrate to an allowable concentration has been accomplished at the pH range of 5-7 with energy consumption value of 1 x 10(-3) kWh g(-1). In electrocoagulation, an allowable concentration of nitrate has been achieved at the pH range of 9-11 with energy consumption value of 0.5 x 10(-4) kWh g(-1). Full removal of nitrate was also possible but with higher energy consumptions for these two methods. (C) 2002 Elsevier Science B.V. All rights reserved.
