Numerous municipal waterworks face the problem of increaseng concentration of nitrates in surface and ground waters.At present, it is possible to reduce these nitrate concentrations to the European Ciommunity, the World Health Organization and Polish permitted standards of 10-25 mg/square dm by missing groung waters with the water from sources with low nitrate concentration.In this case withoput such option, a reliable and cost-effective process for the separation must be applied.Ion exchange and biological denitrification processes are offered as a solution to the problem.Membrane processes as well as ultrafiltration combined with biodegradation and nonfiltration combined with ion exchange or reverse osmosis can be more effective than classical solutions, as far as the technical and economic aspectsvare concerned.The paper presents applications of membrane processes in the denitrification of drinking water.
