The specific functional groups of the anion exchanger provide Purolite A520E with high selectivity for nitrates and allow using А520Е even for the case of nitrate removal against the background of moderately high sulphate content in water. Due to the high selectivity of nitrates, the exchange capacity of the anion exchanger is somewhat lower than the standard highly basic resins, but due to this, there is no abrupt penetration of nitrates into purified water, which is observed in cation exchangers, say for water softening.
Purolite A520E must be regenerated with a solution of tableted salt, which is used to regenerate water softeners. Before using purified water for the food industry, it is necessary to carry out forced regeneration of the apparatus so that the Purolite A520E resin is saturated with chlorine ions.
 
Advantages:
  • The main advantage of Purolite A520E cation exchanger is its selectivity for nitrates and water purified through a layer of ion exchange resin of this type can be used in the food industry and for purifying drinking water;
  • Another advantage of A520E is the ability to somewhat reduce the concentration of sulphates and the alkalinity index.
