Membrana GmbH, a leading membrane and membrane device manufacturer, has obtained GOST R certification for 3M Liqui-Cel Membrane Contactors and 3M Liqui-Flux Ultrafiltration products. The GOST R certification was issued February 14, 2013 and confirms Membrana’s compliance with Russian health and safety standards.

Membrana-Charlotte combines application knowledge and membrane contactor technology expertise to provide innovative separation solutions. 3M Liqui-Cel Membrane Contactors have low energy requirements and can reduce chemical use which contributes to low operating costs and supports customer sustainability objectives. 3M 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. 3M 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.

3M Liqui-Flux Ultrafiltration Modules are used in in many water treatment applications, including wastewater re-use, pre-treatment to RO, process water and drinking water. These devices use UltraPESTM capillary membrane for superior permeability and mechanical strength. Using proprietary Multifiber P.E.T.® Technology, hollow fibers are entwined with a spacer yarn that provides additional membrane stability. These multifiber strands are encased in rigid polypropylene nettings that are positioned in an advantageous hydrodynamic arrangement inside of a PVC vessel. This arrangement forms a narrowing annular gap, ensuring even pressure distribution during backwash.
