PRESSURE DROP - The graph above
shows the expected pressure loss per foot of bed depth as a function of flow
rate at various temperatures.Features
- Highest operating capacity of any nitrate selective
resin.
- Uniform particle size.
- Low pressure drop, superior kinetics.
- Superior, physical stability.
- Low sulfate selectivity and high operating capacity.

ProSelect™ Nitrate represents one
of the newest advancements in ion exchange technology. This is one of the first
resins to be preferential to nitrates over sulfates and other ions in the
water. It removes and than holds onto nitrates so they aren’t dumped back
into the water supply. This makes ProSelect Nitrate the perfect choice to solve
nitrate contamination problems in well water applications.
†CAUTION: DO NOT MIX ION EXCHANGE
RESINS WITH STRONG OXIDIZING AGENTS. Nitric acid and other strong
oxidizing agents can cause explosive reactions when mixed with organic
materials such as ion exchange resins.
