The Pilot Test on the Removal of Nitrate in Ground Water by Electrodialysis Reversal (EDR) Method

摘要：

The maximal concentration of nitrate in the ground water in South of Beijing is 25 mg/L(NO3-N), which is much higher than the drinking water standard of China (NO3-N, 10 mg/L). Hence, its urgent to find a proper way to remove the NO3 from ground water. In this study, Electrodialysis reversal (EDR), an economical and highly effective process for selective elimination of nitrates from drinking water, was used to remove the nitrate from the ground water of Beijing. Based on a pilot plant of EDR system, a long term test had been continued during mutative seasons. The performances of two anion exchange membranes, the desalination efficiency, the operation stability and the economical performance were tested. The results obtained prove that EDR is a technical and economical solution to the problem of selective elimination of nitrates from drinking water.
