Nitrate Removal Plant ion exchange Grimsbury

Any water boreholes identified at risk from nitrates or arsenic are normally fitted with an Ion Exchange System to remove the chemical elements and ensure safe drinking water. However, in order for the nitrate removal process to operate efficiently, the Ion Exchange resin vessels must be kept free from solid particles.

A BOLLFILTER Automatic Type 6.18 is the ideal way to  protect Ion Exchange Systems from potential blocking or damage from solids. By pumping raw water from the borehole to the Ion Exchange vessels through a BOLLFILTER Automatic Type 6.18, all solid particles (down to 50 micron) will be automatically removed. BOLLFILTERs Automatic feature a self cleaning, backflushing design that ensures efficient, long life without the need for regular cleaning or maintenance. As a result, they are ideal for protecting a water treatment plant even in unmanned situations.

By installing a BOLLFILTER Automatic System for nitrate or arsenic removal via Ion Exchange, the life of the resin in the vessels is extended and the requirement for resin backwashing is reduced.
