Membrana Enters Into An Agency Agreement With Sriarayathep Co., Ltd. To Expand Distribution Network Into Thailand
Membrana-Charlotte has entered into an exclusive agency agreement with Sriarayathep Co., Ltd for Liqui-Cel® Membrane Contactors. This agreement establishes a firm distribution channel in Thailand and provides customers with a local representative to handle service and support. The agreement became effective January 1, 2013.
“This agreement aligns with our strategy to expand our distribution and presence in Southeast Asia,” states Chad Schuchmann, Liqui-Cel® Membrane Contactor VP. “It also allows us to leverage Sriarayathep’s considerable knowledge of the local market for new business opportunities.”
Membrana-Charlotte combines application knowledge and membrane contactor technology expertise to provide innovative separation solutions. Liqui-Cel® Membrane Contactors have low energy requirements and can reduce chemical use which contributes to low operating costs and supports customer sustainability objectives. Liqui-Cel® Contactors are modular and compact and can achieve very low dissolved gas outlet concentrations. They are rapidly replacing older deaeration technologies as the product of choice in power generation, semiconductor, hydrocarbon, food and beverage, pharmaceutical, analytical/biotechnology and many other industries. Liqui-Cel® Membrane Contactors also operate cleanly and require a much smaller footprint compared to other technologies. These devices have processed over 620,000 m3/hr (2.7 million gpm) of liquids worldwide and have been operating in a variety of applications for over 20 years.
Thousands of microporous hollow fibers are incorporated into Liqui-Cel® Membrane Contactors that add or remove oxygen (O2), carbon dioxide (CO2), nitrogen (N2) and other gases to or from different liquids. In typical operation, Liquid flows across the membrane hollow fiber 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.
Dissolved CO2 removal from water can improve Ion Exchange (IX) and EDI/CDI efficiency after RO. For example, In EDI/CDI systems excess CO2 can lead to the formation of ionic species that contribute to the total ionic load of an EDI unit, resulting in higher conductivity. In IX systems, reducing dissolved CO2 concentration lowers bed regeneration frequency resulting in more efficient operations. Chemical consumption, such a NaOH, can also be reduced in double pass RO systems.
O2 also negatively impacts many processes; it is corrosive and can oxidize water treatment system components. 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 Liqui-Cel® Membrane Contactors 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.
