Degassing membrane, also known as membrane contactor, is a kind of® membrane separation product with gas-liquid or liquid-liquid mass transfer. By packing a large num ber of membrane filaments, mass transfer interface is provide₽d by a large number of micropores on the membrane surface. Due to tΩhe very small size of the membrane filaments, the interface area of two-phase mass transf™er provided by membrane contactor is much larger than that of most traditional equipment such< as the absorption column and packed column, so it has a very high total mass transf&er rate. This technology can efficiently remove gaseous substances such as oxyge↕n, carbon dioxide, ammonia, trace alcohol vapor and VOD in water, and can also be direc‍tly used to remove ammonia in gas.

3M's Liqui-Cel degassing membrane features a compact design and can provide efficient d₩issolved gas control. These gas transfer configurations are capable ≠of adding gases to or removing dissolved gases and bubbles from a co∑mpatible liquid flow. For more than 20 years, Liqui-Cel degassing membranes have replaced vacu₽um columns, forced ventilation deaerators and oxygen scaven✘gers on a large scale around the world.

At present, degassing membrane is mainly used in thermal deaeration, chemical industry, steel,​ integrated circuit, photoelectric, packaging, power plant, food, beer and beverage, ©camera and medicine and other fields, to remove gas in the liquid to meet the productδion needs of different industries. The removal of oxygen can reach the level of 1ppbΩ, the removal of carbon dioxide can provide PH7.5 ¥water production, and the degassing efficiency can be up to 99.99%.

Since the establishment of Guochu technology (Xiamen) Co., Ltd. We hav↑e taken membrane separation technology as our core and committed to th±e promotion of new separation technology. We have provided comprehensive filtration and purificati≠on solutions to biopharmaceutical, food and beverage, ferment₩ation, agricultural products deep processing, plant extraction, petroleum and petrochemical,> environmental protection water treatment, gas separatiαon, chemical industry and other industries to meet the highly differeεntiated needs of different customers.

Guochu Technology has strong R&D strength and new industry expansion ability.↑ In order to further promote and extend the application of Liqui-Cel degassing memb€rane products in mainland China, 3M Company and Guochu Technology have reached formal cooperation. §Guochu Technology (Xiamen) Co., Ltd. will vigorously promote the new applications of Liqui-Cel deg↕assing membrane products in food, beverage, dairy, metallurgy→, chemical, machinery, environment and other fields, to provide m∏ore users with professional solutions.
