ION EXCHANGE RESINS
NITRATE REDUCTION RESIN
NITRATE REDUCTION RESIN
Nitrate Reduction resin is designed to remove increased levels of nitrates in
raw water. It does this through ion exchange, replacing the nitrate in the water
with chloride molecules that come from regular softener salt (Sodium Chloride.)
Working in the same vein as softener resin, capacity is calculated using the
total volume of resin, and will need to be regenerated when that capacity is
reached with a brine solution.
Wateq would always recommend a metered control valve when using Nitrate reduction resin to limit wasted salt usage and keep running
costs down. Nitrates become increased due to them leaching into the water table from the natural surroundings. Farmland is fertilised and
then washed away.
Because nitrate media uses Ion exchange it will need to include a brine tank.
