Membrana, a leading membrane and degassing device manufacturer, is pleased to announce that it has expanded its ability to service various water treatment sectors that require the NSF Mark for drinking water components. Liqui-Cel®  High purity 10 x 28 Membrane Contactors and Liqui-Cel®     14 x 28 Membrane Contactors, both with X-40 and X-50 membrane, have successfully passed all testing requirements and document reviews at NSF. An official NSF listing can be found at  http://www.nsf.org/Certified/PwsComponents/Listings.asp?Company=4R810&Standard=061&

Many Liqui-Cel® Contactors already meet FDA requirements pert title 21of the Federal Code of Regulations. Adding the NSF Mark to some of the Liqui-Cel® products now allows the contactors to be safely utilized in drinking water systems as well. Using Liqui-Cel® Contactors in Municipal Water applications is a new application of Membrane Contactors where the NSF Mark is required.

Liqui-Cel®, MicroModule®, MiniModule®, and SuperPhobic® Membrane Contactors are used around the world for adding or removing oxygen (O2), carbon dioxide (CO2) and nitrogen (N2) to or from different liquids in digital printing, analytical/biotechnology, semiconductor, power, pharmaceutical, photographic, food and beverage, and many other industries.  For example, O2 negatively impacts many processes; it is corrosive and can oxidize materials. In the power and industrial areas, piping and equipment are susceptible to corrosion. Specifically to the semiconductor and ink market, high levels of dissolved gases can cause lower yields and slower process speeds.

Liqui-Cel® Contactors are also used to add gasses to liquids to enhance megasonic cleaning.  The beverage industry looks to membrane contactors for carbonation, nitrogenation and deoxygenation. These reflect only a few examples of the variety of applications where Membrana Membrane Contactors are used.

Membrana’s Filtration Group also manufactures a variety of membranes and devices used for filtration in various industries and applications.
