36" x 72", Nitrite Duplex Commercial Filter, Clack WS2CI Digital Meter Controller, 26m³/hr

This system is composed of a vessel that is filled with nitrate selective resin and a multi-port valve on the top. This works by the water passing through the resin and trapping the nitrate. Occasionally, this nitrate will need to be removed by regenerating with salt. A time based regeneration system is recommended due to the nitrate levels varying from month to month. The legal limit for nitrates is 50mg/l. Smaller systems can be cabinet based, whereas larger systems come with a separate brine tank to hold the salt.
