Take nitrates out of your water supply.
A whole-system nitrate reduction platform built around ResinTech SIR-100-HP — a nitrate-selective ion exchange resin. Available in 6 GPM and 10 GPM models, the NWS-NITRATE series delivers high operating capacity and low nitrate leakage for homes and small facilities on affected water supplies.
Built to order for your application
Each NWS-NITRATE system is assembled specifically for your order. Typical processing time is 3–5 business days before the system ships.
Two sizes, one proven platform
Both models share the same nitrate-selective resin and metered control valve — pick the flow rate that matches your household or facility demand.
Sized for typical residential whole-home use on a nitrate-affected supply.
Higher capacity for larger homes or small commercial demand.
What are nitrates, and how do they get into water?
Nitrates are naturally occurring compounds formed when organic matter decomposes, and they are also a common component of fertilizers. Because nitrates are highly soluble and don't bind to soil, they move easily into groundwater.
In drinking water, nitrates are colorless, odorless, and tasteless — there's no way to detect them without a water test. That's what makes regular testing so important for anyone on a private well.
Nitrates and your water
High nitrate levels in drinking water are a recognized health concern, and the U.S. EPA has set clear guidance for testing and acceptable limits.
EPA Maximum Contaminant Level
The U.S. EPA has set the Maximum Contaminant Level for nitrates in drinking water at 10 parts per million.
Recommended Testing
The EPA recommends that well users test their water for nitrates every one to three years.
Sensitive Groups
High nitrate levels can cause serious illness, particularly in infants, young children, and adults with certain enzyme deficiencies.
Engineered around nitrate-selective resin
At the core of every NWS-NITRATE system is ResinTech SIR-100-HP — a chloride-form, microporous, nitrate-selective strong base anion resin.
Nitrate-Selective by Design
SIR-100-HP increases selectivity for nitrate while decreasing selectivity for sulfate — so it targets the contaminant you're trying to remove.
Higher Operating Capacity
Its selectivity profile delivers higher operating capacity than standard type 1 or type 2 anion resins — more water treated between cycles.
Lower Nitrate Leakage
Compared to conventional anion resins, SIR-100-HP produces lower nitrate leakage — more consistent treated water quality.
Metered Control Valve
A 1" metered control valve monitors gallons used and includes a programmable service reminder — set it to time, gallons, or both.
WQA Gold Seal Resin
The SIR-100-HP resin is Gold Seal Certified by the Water Quality Association (WQA) for use with potable water.
Complete & Ready to Install
Ships as a full assembly — mineral tank, resin, control valve, system bypass, and charcoal brine tank with safety valve.
Ion exchange, simplified
Nitrate ions carry a negative charge. The chloride-form anion resin is engineered to swap them out as water flows through the mineral tank.
Water Enters
Nitrate-bearing water flows into the mineral tank through the 1" metered control valve.
Resin Exchanges Ions
The SIR-100-HP resin captures nitrate ions and releases harmless chloride in their place.
Regeneration
The system periodically regenerates the resin using brine from the charcoal brine tank, restoring capacity.
What ships with each system
Every NWS-NITRATE system is built to order as a complete, install-ready assembly.
Polyglass Mineral Tank
10" × 54" on the 6 GPM model, 13" × 54" on the 10 GPM model — sized to match flow capacity.
ResinTech SIR-100-HP Resin
The nitrate-selective ion exchange media at the heart of the system.
1" Metered Control Valve
Monitors gallons used, with a programmable service reminder set to time, gallons, or both.
Charcoal Brine Tank with Clack 474 Safety Valve
1517 brine tank on the 6 GPM model, 1840 on the 10 GPM model, with an integrated safety valve to guard against overflow.
System Bypass
Lets you isolate the system from your plumbing for service or maintenance without shutting off the home.
