Gas Transfer Membrane Container MPW’s degasification services treat boiler-feed water and chemical use, resulting in lower operating costs.

Degasification membranes control dissolved gasses, such as carbon dioxide and oxygen, in water systems. These gasses react with metals in the boiler system, resulting in boiler corrosion. MPW Industrial Water’s degasification services remove these contaminants to protect the boiler. Membrane contactors contain micro-porous hydrophobic membranes, which are used to bring gas and liquids in direct contact without mixing. Contactors operate by lowering the pressure of gas in contact with the liquid to create a driving force to remove the dissolved gasses from the water. When compared with chemical treatments, degasification produces significant customer savings in product, blow down and energy.

Utilizes two gas transfer membranes and a vacuum pump to remove ~87-90% of CO₂

Placed in an interpass configuration next to a DI trailer between cation and anion tanks.

Balances anion resin to increase volume of cation resin used in DI trailer.
