Dow Filmtec Commercial Reverse Osmosis (RO) Membranes

Filmtec commercial RO membranes

replacement reverse osmosis membrane elements from 500 to 2,600 GPD for commercial and light industrial applications

Whether you demand the highest purity water or the lowest cost water production, there is a commercial / industrial Filmtec element for you.

Reverse osmosis membrane elements are used to purify water for drinking, provide spot-free rinse water, purify water for laboratory uses and for dialysis, and other applications where low mineral content water is desired. When used in systems producing up to 2 m3/hr (10 gpm), these are considered commercial applications.

Filmtec offers a wide range of commercial / industrial membrane elements to meet the needs of these varied applications. Filmtec products are differentiated primarily based on membrane performance and element size. From products delivering the highest quality water (BW30, TW30) to the lowest pressure RO element (XLE) to a combination of low energy and high solute rejection (LP, BW30LE), there is a Filmtec RO element for nearly every system.

When choosing between elements with or without a fiberglass outer shell, please consider that the membrane and element performance is the same between the two different element types. Due to structural strength, fiberglassed elements are recommended for systems with three or more elements in a single housing. Taped elements are recommended for systems with one or two elements per housing.

Note: Permeate flow rates for individual elements may vary +/-20%, and will also be influenced by feed water conditions.

Notice: The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system.
