The sources from which nitrogen compounds enter the watercourses are described and the adverse effect of nitrogen forms on water quality is determined. Nitrogen compounds present in the water taken may be removed by physicochemical and biological methods. Particular attention is given to the significance of ammonia nitrogen and nitrates which occur in groundwater. In Poland, use has been made of dry filtration and filtration through pyrolusite beds for ammonia nitrogen removal and ion exchange for the removal of nitrates. Both the processes are in use on a commercial scale, and pyrolusite beds have found wide acceptance in groundwater treatment.
