Nitrate removal by Reverse Osmosis uses a semi-permeable membrane to selectively remove various inorganics within the water. Pressure is applied to the water to force it through the membrane. As the water passes through the membrane it leaves the impurities behind. Estimates predict that 85 to 95 percent of nitrates can be removed with reverse osmosis. Actual removal rates may vary, depending on the initial quality of the water, the system pressure, and water temperature.

Do I Have Nitrates in My Water?
If you suspect a problem and your drinking water comes from a private well, you should have the well tested. If Nitrates or any other contaminant is found RAdata can install Water Treatment systems to treat any water problem.
Test My Water for Nitrates (and other contaminants)
RAdata provides a full water testing service, to learn about our Water Testing Service or get started, contact us to order well water testing for your home.

Treatment: Anion Exchange Water Softener (Countercurrent Regenerating)
A specialized type of Anion exchange water softener is used to remove nitrates. A water softener uses the principle of ion-exchange – in this case, anions – to remove nitrates from raw water. The equipment contains a “bed” of softening material known as ‘resin’ through which the untreated water flows. Although the anion softener looks the same on the outside, this unit is very different from a standard “cation” water softener. As water passes through the resin, the nitrates in the water attach themselves to this material. This ion-exchange process occurs literally billions of times during the softening process. Weekly automatic regeneration, or recharging, is necessary. The unit is set to automatically perform this regeneration as needed, based on water usage. To recharge the resin, it must be rinsed with a rich brine solution (Sodium Chloride – salt).
This washes the nitrates out of the resin and replaces them with chloride, so the resin is once again ready to exchange ions to remove more nitrates. During the recharging cycle, the unit is also backwashed. Reversing the normal flow of water also serves to remove any turbidity and sediment, which may have accumulated during the softening process due to the filtering action of the ion exchange material. Backwashing also loosens and fluffs up the bed of resin. Countercurrent regenerating water softeners add the salt against the service flow and use significantly less salt than traditional water softeners. Our softeners are controlled using Clack® WS-1 control heads, which offer the option of either metered “demand initiated regeneration” or the more traditional “timed” regeneration.
