Degasifiers
Membrane Contactor Degasifier Systems
ART membrane contactor degasifier systems use Liqui-Cel® microporous hollow fiber membranes to remove gases from liquids efficiently and effectively.
During typical operation, the liquid flows over the shell side (outside) of the hollow fibers while a vacuum is applied to the lumen side (inside) of the fibers. This pressure differential forces dissolved gases through the membrane pores, where they are removed by the vacuum pump.

Notes
- System feed water must be pretreated down to 5 micron filtration level.
- Minimum and maximum feed flows as specified.
- Systems rated at 77°F (25°C) using RO permeate water. System capacity changes with degasification requirements. For higher degas requirements, a water analysis must be supplied and could result in modifications to the system.
- RO system is recommended for pretreatment. Contact us for additional details on your specific application.

About Degasifiers with Liqui-Cel® Membrane Contactors
ART water degasifier systems use Liqui-Cel membrane contactors, leading gas transfer devices that have been used in many industries around the world for over 40 years. Carbon dioxide removal and deoxygenation are among the common applications. Capable of achieving <1ppm CO2 and <1ppb O2, ART Water Degasifiers using Liqui-Cel membrane contactors provide significant benefits to industrial processes by removing gases from liquids. For example, carbon dioxide and oxygen removal can reduce the impact of corrosion on boilers and piping to protect captial investments and reduce operating costs. Removing these gases can also improve process efficiency and prevent negative impacts on production yields related to dissolved gases. Because of their cleanliness and predictability, Water Degasifier systems using Liqui-Cel Membrane Contactors are the standard degassing technology installed in ultrapure water systems for the semiconductor, microelectronics and many other industries.
Although other degassing technologies, such as vacuum towers and forced draft dearators have existed for many years, these older methods are being rapidly replaced by degasification systems using Liqui-Cel Membrane Contactors due to the smaller footprint, lower installation costs and the modular nature of the membrane contactor system.
How Water Degasifier Membrane Contactors WorkART water degasifiers use Liqui-Cel Membrane Contactors with a microporous hollow fiber membrane to remove gases from liquids. The hollow fiber is knitted into an array and wrapped around a center tube inside of the contacter housing. During typical operation, liquid flows over the shellside (outside) of the hollow fibers while a vacuum is applied to the lumenside (inside) of the fibers. Because the membrane is hydrophobic it acts as an inert support that allows direct contact between a gas and liquid phase without dispersion. Applying a higher pressure to the liquid stream relative to the gas stream creates the driving force for dissolved gas in the liquid to pass through the membrane pores. The gas is carried away by the vacuum pump. |
