NWS Nitrate Reduction System - 6 GPM

The NWS Nitrate Reduction System rated at 6 GPM is a Nelsen Water Solutions anion-exchange system built to lower nitrate levels in residential and small-flow water supplies. Nitrate contamination is a common concern for private wells in agricultural areas, where fertilizer runoff, septic influence, and other sources can push concentrations above safe thresholds and create a genuine health concern for the household, particularly for the most vulnerable members of the family.

This system uses nitrate-selective anion-exchange resin to capture nitrate ions from the water and replace them with harmless chloride, then regenerates with a salt brine much like a conventional water softener. Nitrate-selective media is specifically formulated to favor nitrate even in the presence of competing sulfate, which is important because non-selective resins can otherwise release previously captured nitrate back into the water when they become loaded with sulfate—a phenomenon known as nitrate dumping that selective resin is designed to avoid, providing more consistent and trustworthy protection.

System highlights

• 6 GPM rated flow for residential and light use
• Anion exchange engineered for nitrate reduction
• Nitrate-selective resin chemistry to resist nitrate dumping
• Regenerates with common salt brine
• Approximately 114.22 lbs as configured
• Suited to private wells in agricultural areas

Because nitrate is a serious health concern—particularly for infants—effective and reliable reduction genuinely matters, and the choice of selective resin is what makes the difference between dependable performance and unpredictable results. For best performance, confirm your nitrate and sulfate levels with a water test before specifying the system, since the ratio between them affects both capacity and behavior. Size the system appropriately to your flow rate and contaminant load, and maintain the brine supply so regeneration proceeds on schedule and the resin's nitrate-removing capacity is consistently restored. A practical, salt-regenerated solution for households facing elevated nitrate, the 6 GPM system brings dependable, well-engineered nitrate reduction to homes that need it most. Properly tested, correctly sized, and consistently maintained, the 6 GPM nitrate system gives affected households reliable, well-engineered protection where it counts most. A dependable answer for families who need trustworthy nitrate reduction at home. Pairing the system with periodic water testing lets you confirm it is keeping nitrate safely in check over time.
