DuPont Filmtec
Hydranautics
Welcome to Australia's premier online supplier of Dow Filmtec, Hydranautics, GE and CSM Reverse Osmosis and Nanofiltration Membranes. Founded in 2000 we have been supplying Membranes for all types of water treatment applications with a focus on ensuring we stock a large range of models, for timely delivery at a great price.
There are a number of ways to find the reverse osmosis membrane that you are after. If you know the model number you can enter it in the search bar at the top of this page. Eg. Type SW30-4040 or ESPA2 and then select your membrane from the results. Alternatively if you know the application you can use the Menu at the top. Go to Membranes and then select a sub item such as "Brackish Water" or "Sea Water" to be taken to the relevant membrane category. Finally you can browse the brands by either clicking the relevant manufacturer's logo or from the menu system.
If you are unable to find the Reverse Osmosis Membrane that you require, please Contact Us either via phone or email as we may be able to source the membrane for you or offer an alternative that is currently stocked.
This 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.
We also offer a Reverse Osmosis 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 arrange to have it dissected and inspected. Additional chemical analysis is available for a modest fee.
