Nitrate Removal by Continuous Electropermutation Using Ion-Exchange Textile: II. Experimental Investigation
2006 (English)In: Journal of the Electrochemical Society, ISSN 0013-4651, Vol. 153, no 4, D62-D67 p.Article in journal (Refereed) Published
Water with nitrate concentrations above 100 ppm has been treated with continuous electropermutation which partially substitutes the nitrate with chloride. The performance of a textile anion exchanger as conducting spacer in the feed compartment of an electropermutation cell was investigated. Experiments with and without textile are compared and the influence of the textile is discussed. The process could, using the textile, successfully treat feed water with 105 ppm nitrate to produce a water with less than 25 ppm nitrate. The importance of establishing a good contact between the membranes and the textile spacer was pointed out. The experimental results were compared to model predictions and a good agreement was found.
