While working on adding Dow Filmtec membranes to the Nalco eCommerce site, I came across this interesting list of discontinued FILMTEC™ RO and NF products on the Dow Filmtec website. Before you consider substituting an older Reverse Osmosis or Nanofiltration membrane for a new version, contact us to run a projection on your system to determine if you will continue to have the water of the quality and quantity you need after the substitution. As you can see below, to complicate the substitution, there are often primary and secondary options. The following was extracted from the DOW FILMTEC™ website.
DOW FILMTEC™ RO/NF Discontinued Products
DOW FILMTEC™ RO/NF Recommended Replacement Product [PRIMARY]
DOW FILMTEC™ RO/NF Recommended Replacement Product [SECONDARY]
Please remember to contact us before you substitute.
