Leading international manufacturers include DOW FILMTEC, GE OSMONICS DESAL and HYDRANAUTICS with a combined manufacturing history of more than 100 years in the field of Semipermeable Membranes used for Reverse Osmosis and Nanofiltration.

The site also contains links to extensive resources supplied by each membrane manufacturer including membrane selection guides, substitution charts, brochures, data sheets, theory, application libraries, maintenance methods and troubleshooting guides.

Experienced technical advice is available on-line. If what you want a membrane that is not listed then email us for a special quote.

We also offer a MEMBRANE AUTOPSY SERVICE to assist you in determining the cause of premature membrane failure. When you change out your current membranes, send us the first and last membrane from your array and we will disect and inspect it FREE. Additional chemical analysis is available for a modest fee.

REVERSE OSMOSIS MEMBRANES are manufactured with different pore sizes and support structures. Use the selection guides and substitution charts available in each category to determine the correct membrane for your application. When retrofitting membranes do not exchange low energy with high rejection types without consulting a process designer. If in doubt email sales@membraneshop.com.au .
