Membrane Structure

A variety of membranes are used at the sea water desalination center.

UF Membrane

Polyvinylidene Fluoride (PVDF) Spiral Type

* UF membranes can remove colloidal materials (*) and viruses from raw water as the water passes through them.

* A colloid is a substance composed particles ranging from 10-6 to 10-7 in size.

High-Pressure RO Membrane

Cellulose Triacetate Hollow Fiber Type

* High-pressure RO membranes

can efficiently remove dissolved salts as filtered water passes through wound up hollow fibers.

Low-Pressure RO Membrane

Polyamide Spiral Type

* Low-pressure RO membranes

are used for the adjustment of the quality of the feed water as the feed water passes through several alternating layers of flat-sheet membrane which have been rolled up.
