The US Water American Revolution AR-6 Reverse Osmosis System is for medium commercial applications. It uses a Goulds® multi-stage booster pump to deliver up to 4,000 gallons per days of permeate flow. It is highly customizable for any application.

US Water is breaking the traditional pre-packaged commercial reverse osmosis system mold by introducing the first fully-customized, built specifically for your needs, commercial grade reverse osmosis system. We don't think you should have to buy what a company has on their shelf - we think you need to buy exactly what you need! Even if you are not sure exactly what you need, we can help you decide. A properly sized and outfitted system should last 20+ years. That's what you get when you do it right the first time.

Test Parameters: *550 TDS Filtered (5 Micron), De-Chlorinated, Municipal Feed Water, 65 psi (4.50 bar) Feed Pressure, 100 psi (6.89 bar) Operating Pressure, 77 Degrees F (25 Degrees C), Recovery as stated, 7.0 pH. Data taken after 60 minutes of operation. Scale prevention measures must be taken to prolong membrane life.

Low temperatures and high feed water TDS levels will significantly affect system's production capabilities. Computer projections should be run for individual applications which do not meet or exceed minimum and maximum operating limits.

NOTE: US Water rates their reverse osmosis systems under industry standards which are tested at 77 degree F, 500 TDS and 60 psi pressure. Production can vary dramatically depending upon water pressure, temperature and TDS (total dissolved solids) levels. US Water does not make these standards - we just adhere to the industry standards when testing and report what the standards require. Every manufacturer uses these standards.
