In current work the general methods and technologies used for the removal of nitrates from groundwater, waste and drinking water are studied. Each of the denitrification methods has numerous disadvantages, so their individual use is ineffective. Last years a complex use of the investigated methods is being developed. In this work we propose the use of complex wastewater denitrification on the base of ion exchange and catalytic reduction of nitrates in secondary water flow in the presence of
