Product Description

Nitrate is an essential nutrient for the growth of plants and microorganisms. However, excessive concentration of nitrate in water affects aquatic environment and causes health hazards for people.

Nitrate contamination of water is one of the most serious environmental and health problems worldwide. High nitrate concentration in water can cause abundant development of aquatic plants, growth of algae, have harmful effects on fish and other aquatic life and disturb the ecological balance of organisms present in water. In addition to this, the presence of excessive nitrate ions in drinking water is a potential public health hazard as the formation of nitrate compounds in the stomach has been shown to be carcinogenic .


The World Health Organization (WHO 2006) accepted the maximum allowable nitrate concentration in drinking water as 50 mg NO3 -/L (11.3 mg N/L). Therefore, nitrate is a water pollutant under regulation, and it is necessary to reduce its concentration prior to discharge or being used for drinking.Nitrate is a stable and highly soluble ion which makes it difficult to remove using conventional water treatment methods such as precipitation and adsorption. Of the various techniques available for removing nitrate, the ion exchange/adsorption process is the most suitable


Purolite A520E is a macroporous strong base anion resin which is specially designed for the removal of nitrates from water for potable processes. The macroporous matrix and special ion exchange group functionality imparts ideal nitrate selectivity to Purolite A520E making this resin particularly suitable for nitrate removal even when moderate to high concentrations of sulphate 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 the Directive No. 80/778 of July 1980. This directive limits the nitrates to a maximum admissable concentration (M.A.C.) of 50 mg NO3/l. The U.S.A. drinking water regulations limit nitrates to 45 mg NO3/l.

What is Reverse Osmosis?

Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.

Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules.
