Z-XM Nitrate Treatment System

WRT’s nitrate removal system consists of utilizing a regenerable ion exchange media. Currently the media, trade named Z-XM is a nitrate selective synthetic ion exchange flow-through media. The media is a specialized strong base anion exchange resin of styrene-divinylbenzene base structure. The media is contained in a screened pressure vessel wherein untreated water is pumped down flow packed bed through the vessel for the service period. Following the recommended service interval measured in volume throughput, the pressure vessel is placed in a batch regeneration mode. Regeneration consists of contact with a calculated volume of concentrated sodium chloride brine for a specified time period. After a brief rinse period, the vessel is placed back into service. Waste brine containing nitrate contaminant is either collected for disposal or directed to a suitable wastewater discharge hub/sewer.
