U.S. Manufacturer Orders Ultrahigh Pressure Reverse Osmosis System

An order for reportedly the first full-scale industrial ultrahigh-pressure reverse osmosis (UHP RO) system was receive by Saltworks. The new system includes spiral-wound membranes rated to 1,800 psi (124 bar). A U.S. manufacturer of advanced materials will use the system to achieve a tenfold reduction in disposal volume while recovering clean water for reuse.

Ultrahigh pressure reverse osmosis is based on seawater reverse osmosis systems, but it operates at a 50 percent higher pressure to halve the volume of brine generated. According to Saltworks, this means less waste and more clean water.

Saltworks has pilot tested ultrahigh pressure reverse osmosis on applications including cooling tower blowdown, mining waters, factory wastewater and ion exchange regeneration waste.

Avoiding scale, corrosion and microbiological growth — all of which diminish effective heat transfer — is the focus of any water treatment approach for water-contacted process heating and cooling equipment.
