Purolite® A520E
Macroporous Strong Base Anion
Exchange Resin
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.
