The 10 inch nitrate reduction cartridge house a specicially designed strong based anion exchange resin used for the reduction of Nitrates in water even when high levels of sulphates are present.
Harmful nitrates are exchanged for harmless chloride ions as they pass through the resin bed (the same process as a water softener).
Internal pre and post filters protect the nitrate media preventing potential migration.
The 10 inch nitrate reduction cartridge will require eithcer replacing or regenerating at regular intervals. Regeneration can be done by rinsing the media with a salty brine.
