Seaguard
The core of the Seaguard membrane technology is the hydrophilic hollow membrane, composed of a PES/PVP blend. The membranes’ high mechanical and chemical strength makes them extremely durable. The membrane modules are operated inside-out and the ideal choice in UF-RO pretreatment for sea water reversed osmosis systems (SWRO). By removing almost all suspended solids, Seaguard membrane modules protect downstream SWRO systems from fouling. Seaguard membranes are used in horizontally positioned pressure vessels, providing a high membrane area to footprint ratio.
