DOSHION DCHR 78 media is specially designed for the removal of Arsenic present water or
wastewater in terms of Arsenate for potable processes. The special exchange group
functionality imparts ideal arsenic selectivity to DCHR 78 making this media particularly
suitable for Arsenic removal even when moderate to high concentrations of Sulphate are
present. Hence this media gives superior performance in Arsenic removal applications
when compared with other methods of Arsenic Removal.
Arsenic is present in water in Arsenate and Arsenate forms. Arsenate is a neutral species so
for complete removal of Arsenic, it needs to be further oxidized to arsenate for removal as
described above. Oxidation can be accomplished by air stripping the water stream or
addition of an oxidizing agent like peroxide or ozonolysis.
