Liquid Pretreatment for Reverse Osmosis

Liquid Pretreatment for Reverse Osmosis

Reduce costs and water consumption while maintaining a manageable/predictable water system. This cost-efficient system removes hardness minerals and chlorine, prolonging the life of your membrane. With a smaller footprint and less maintenance than softeners and carbon tanks, the antiscalant/chlorine destruct system turns your tap water into suitable water for RO feed. Add the concentrated liquid into the designated containers, add RO water, and you’re ready to go!

Less Labor

  • Easy, one step refill. No re-bedding of carbon or lifting heavy bags of salt
  • No valves, meters, timers to log and monitor daily

Environmentally Friendly

  • Softeners and backwashing carbon systems use hundreds of gallons daily to operate. The NuStream liquid pretreatment system uses less than 1.5 gallons per day.
  • Softeners rinse hundreds of pounds of salt down the drain per week, as opposed to ounces of liquid pretreatment.

Better RO Performance

  • Improving the conductivity of the water fed to the RO improves the performance of the membrane resulting in higher quality RO water.
