SWRO4 Series Sea Water Reverse Osmosis System 380-10,000 GPD Capacity 1000 psi Operating Pressure
Our SWRO4 Series seawater reverse osmosis systems utilize advanced membrane technology to remove over 99% of dissolved salts from seawater, producing high-purity water for various applications. These skid-mounted systems are engineered with corrosion-resistant materials including SS316L, Duplex SS 2205, SS 2207, and SS 904 to ensure durability in harsh marine environments.
Available in capacities ranging from 380 GPD to 10,000 GPD, these systems can handle feed water with TDS levels up to 45,000 ppm. Operating pressures range from 700 to 1,000 psi, making them suitable for high-salinity water sources.

Seawater reverse osmosis systems effectively remove over 99% of dissolved salts through semipermeable membranes. The process involves applying high pressure to force water through membranes while rejecting concentrated saline and impurities, which are then flushed away or processed. These systems incorporate multiple membranes and high-pressure pumps to maximize daily purified water production.
Desalination has become essential for producing pure freshwater in regions lacking drinkable water sources. As traditional water sources become depleted, seawater desalination provides a sustainable alternative by converting abundant ocean water into usable freshwater for consumption and industrial applications.
