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.
This unit is supplied partailly assembled for shipping. Some assembly will be required. All components and instructions will be supplied.
The final figure given in m3 is the capacity of the unit assuming a nitrate level of 50 ppm (the capacity is the volume of water that can be treated between regenerations).
