Purolite A-520E Nitrate Removal Resin - 1/2 Cube

Macroporous Strong Base Anion Exchange Resin for nitrate removal in residential and community water systems.
This is a macroporous strong base anion resin that is specially designed for the removal of nitrates from water for potable processes. The macroporous matrix and special ion exchange group functionality impart ideal nitrate selectivity to Purolite A520E making this resin particularly suitable for nitrate removal even when moderate to high concentrations of sulfate are present. Hence this resin gives superior performance in nitrate removal applications when compared with standard exchange resins. A requirement of the nitrate removal process is to produce potable water meeting the quality standard defined by the European Economic Community in Directive No. 80/778 of July 1980. This directive limits the nitrates to a maximum admissible concentration (M.A.C.) of 50 mg NO3/l. The U.S.A. drinking water regulations limit nitrates to 10 mg NO3/l.
