Charlotte, NC. USA. -- Membrana-Charlotte, a division of Celgard, LLC has entered into a limited exclusive agreement with Layne Christensen Company for Radon and VOC removal for municipal water applications in the continental United States.
Liqui-Cel® Membrane Contactors are leading-edge technology in gas transfer applications and are the accepted norm in many markets. As a market leader, Layne has strong distribution channels in the municipal market segment. Allen Pittman, VP for Liqui-Cel® Membrane Contactors states, “We are very excited about this agreement. This relationship provides an excellent opportunity to expand our presence in this market segment and to establish Liqui-Cel® Membrane Contactors as the technology of choice for Radon and VOC removal applications.”
Membrana and Layne Christensen Company have been working together since 2010 to evaluate the use of Liqui-Cel® Membrane Contactors for Radon and VOC removal in the municipal market.
Liqui-Cel® Membrane Contactors offer a modular degassing option that can be put in virtually any area. They are rapidly replacing older deaeration technologies as the product of choice in digital printing, analytical/biotechnology, semiconductor, power, pharmaceutical, photographic, food and beverage, and many other industries.
Liqui-Cel® Membrane Contactors utilize thousands of Celgard® microporous hollow fibers that are used around the world for adding or removing oxygen (O2), carbon dioxide (CO2), nitrogen (N2) and other gases to or from different liquids. The Extra-Flow design incorporates a baffle in the middle of the contactor, which directs the liquid radially across the array. A strip gas or vacuum, either separately or in combination, is applied on the lumenside of the hollow fibers. Because of its hydrophobic nature, the membrane acts as an inert support to allow direct contact between a gas and liquid phase without dispersion. The dissolved gas in the liquid travels through the pore by applying a higher pressure to the liquid stream relative to the gas stream.
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. In the semiconductor and ink markets, high levels of dissolved gases can cause lower yields and slower process speeds. Liqui-Cel® Contactors are also used to add gases to liquids to enhance megasonic cleaning. The beverage industry utilizes membrane contactor technology for carbonation, nitrogenation and deoxygenation. These applications are only a few examples of the many opportunities where these devices can be used for gas transfer. Membrana’s Industrial & Specialty Filtration Business also manufactures a variety of membranes and devices used for filtration in various industries and applications.
