Remove nitrate / Soften hard water in one system
NITROSOFT® combines selective nitrate treatment and hardness removal in one compact point-of-entry system for residential drinking-water supplies.
Each NITROSOFT® system contains Watch Water® NITROTRAPP® and HARDNESSTRAPP® media in a single fiberglass-composite pressure vessel. The published media ratio is 50:50. NITROTRAPP® targets nitrate ions, while HARDNESSTRAPP® removes calcium and magnesium hardness. An integrated regeneration system restores media capacity, while the adjustable blending valve allows treated and untreated water to be mixed to achieve the commissioned finished-water nitrate and hardness setpoints. Regular laboratory testing and appropriate safeguards are essential because nitrate is an acute drinking-water contaminant.
Two contaminants / One compact treatment system
One system.
Complete household-water conditioning.
Developed for point-of-entry treatment where nitrate and water hardness occur together and both must be controlled before household distribution.
Private Well Water
Treatment of tested groundwater affected by nitrate and hardness.
Single-Family Homes
Whole-house treatment for households of approximately two to six people (NITROSOFT® One).
Multi-Family Properties
Models for two- and three-family residential properties (NITROSOFT® Two & Three).
Agricultural Regions
Treatment of groundwater influenced by fertilizer use and agricultural runoff.
Hard Water with Nitrate
Simultaneous control of nitrate and calcium-magnesium hardness in a single vessel.
Point-of-Entry Drinking Water
Central treatment before water is distributed to household fixtures and appliances.
Four treatment functions / Integrated into one cabinet
Selective Nitrate Removal (NITRATE-CAPTURE)
NITROTRAPP® media captures nitrate ions from the incoming water. Finished-water nitrate concentration must be verified using an appropriate analytical method.
Calcium and Magnesium Removal (HARDNESS-CAPTURE)
HARDNESSTRAPP® media reduces hardness by capturing calcium and magnesium ions, providing conventionally softened water.
Adjustable Finished-Water Blending (PRECISION-BLEND)
A mixing valve blends treated and untreated water to establish the commissioned nitrate and residual-hardness setpoints. Nitrate safety must never depend on an unmonitored manual setting.
Automatic Media Regeneration (REGEN-CONTROL)
The system includes a brine well, brine valve and electrically controlled regeneration process to restore nitrate- and hardness-treatment capacity.
How simultaneous nitrate and hardness removal works
NITROSOFT® combines anion treatment for negatively charged nitrate with cation treatment for positively charged hardness minerals.
- Nitrate-Ion Capture – Nitrate ($NO_3^-$) is a negatively charged ion. NITROTRAPP® contains functional sites designed to capture nitrate while water passes through the media bed.
- Hardness-Ion Capture – Calcium and magnesium are positively charged hardness ions. HARDNESSTRAPP® captures these ions to reduce measured water hardness.
- Layered or Mixed Dual-Media Treatment – NITROTRAPP® and HARDNESSTRAPP® are installed in a 50:50 ratio in one pressure vessel. Final bed arrangement and hydraulic behavior are documented in the installation manual.
- Regeneration and Rinsing – During regeneration, captured nitrate and hardness ions are displaced from the media and transferred into a concentrated waste stream. Correct brine composition, dosage, contact time and rinsing are essential.
