Study of methods for physico-chemical treatment of groundwater from nitrates

Abstract

Contamination of groundwater by nitrogen compounds is an urgent problem. In Belarus for the water supply of cities, towns, industrial enterprises use groundwater. There is a brief description of the operating conditions of underground water and their quality. It describes the impact of nitrates on human health. The most intensive pollution by nitrates at a depth of 10–15 m in the country side and in home gardens. Also at depths of 40–50 m recorded nitrate concentrations, that exceed the maximum permissible level (45 mg/l for of nitrates content). The article studies methods for removal of ammonium nitrogen, nitrates and nitrites from natural waters, presents the results of experimental studies of water purification from nitrates by ion exchange method for drinking water supply purposes.
