High levels of nitrates in water are dangerous (legal limit in potable water is 50mg/l). A nitrate reduction system is made up of a high quality vessel filled with nitrate selective resin with a multi-port valve on the top. The nitrate rich water passes over a resin where the nitrate is exchanged for chloride ions. Periodically this nitrate needs to be removed by regenerating with salt. As the nitrate levels vary from month to month a time based regeneration system is recommended.

We assume 50 ppm NO3 for the capacity of this system. (The capacity is the volume of water the unit can treat before it requires regeneration).
This unit is an automated Timed Controlled unit offering safe nitrate removal from the water supply.

The unit is self cleaning using brine generated from the salt located in the salt bin. Timer controlled allows cleaning cycles to be set from 1-21 days depending on water consumption and nitrate levels.
