## Most comnerclal seawater reverse osmosis plants deslgned to date are driven using a feed pressure In the range of 800-1000 psig (5500-6900 kPa). Membranes rated at 1200 psig (8300 kPa) are now available and it is reasonable to expect membranes capable of even higher pressure operatton \n the ne
When selecting materials for the high pressure piping in reverse osmosis seawater desalination plants many considerations must be made. The corrosion resistance in seawater is of outmost importance for safe and reliable service. In this respect stainless steel UNS S31254 is fully resistant to local
As a means to minimize or eliminate brine disposal problems, high recovery RO must be accompanied by pre-or post-treatment to avoid scale precipitation, almost entirely by CaSO4. All such methods will add to water cost. However, rigorous comparison must be made with the costs and constraints of bri
Polymeric thin-film composite (TFC) reverse osmosis (RO) membranes in a patented spiral-wound element configuration were evaluated at process temperatures to 90°C. The viability of the membrane elements operating at high temperature was successfully demonstrated. The high temperature RO (HT-RO) mem
