EPRO Reverse Osmosis (RO) Water Treatment Systems

The complete line of EPRO Reverse Osmosis (RO) Water Treatment Systems accommodates a diverse range of residential, municipal and industrial applications with flow rates from 500- to 175,000 GPD. From tap water, brackish water, seawater and industrial process water, RO systems remove up to 99.8% of impurities, such as bacteria and dissolved solids, from water by passing water through a semipermeable membrane under pressure.  Clean, pure water – that’s what we deliver.  

RO will remove most dissolved solids (ions) and other constituents that can can stain fixtures and laundry, give flower and vegetable plants the ability to uptake minerals from the water.   The result is water that is very low in minerals and alkalinity.

You deserve clean, pure water in your home. EPRO Residential Reverse Osmosis systems are designed to maximize water purification efficiency and produce high-quality clean water is supplied through existing taps (faucets).

EPRO industrial applications that rely on high -efficiency, high-purity water.

Product Overview

Even from a trusted municipal source, water quality can vary over time and season. Rainfall, organic loading, amount of sun, and reservoir water height can all influence the water that feeds our consumption. Add to this the effects of water purification—chlorine or chloramine, how loaded was the sand filtration and carbon systems, how long was the water in the pipe, how warm or cold was the ground the pipe was in, what were the pipes made of—all these influences the water at your tap.

Maybe the water in these systems of your property smells a little, leaves stains on the sinks, has organic material or has a very high pH (the cause of “hard” water).  You need clean water supplied through existing taps (faucets).

Whatever your treatment needs, Newterra offers the reliable best solution to provide the purest water. These systems are engineered from the ground up to provide maximum treatment efficiency in a compact, skidded package for your application.
