Assessment of efficiency of denitrification of underground water by electrodialysis. Currently, the nitrogen compound contaminated in number of borehole waters in rural areas even in Hanoi suburb area [SHER, 2004] is much concerned because the risk for human consumption. Therefore, an urgent need for water denitrification and water desalination exists in these areas. Electrodialysis (ED) is an efficient method for the treatment of drinking water with high ammonium concentration, even it achieves only a transfer of pollution by producing concentrated brines. This study aims to evaluate the efficiency ED system in nitrogen compounds removal from water. Experiments performed at laboratory scale with prepared solutions and household scale to treat a ground water contaminated by ammonium, nitrate, and nitrite. |
