Vacuum degasse is utilized to remove O2, CO2 and N2 and is capable of producing water with part-per-billion levels of these dissolved gasses. This type of equipment is part of the final polishing stage of a water treatment process to produce ultra high purity water.
VACUUM DEGASSERS SPECIFIC TECHNOLOGY
Vacuum Degasification systems are custom designed to reduce oxygen,carbon dioxide, and nitrogen to meet the rigid effluent requirements of any application.
HOW IT WORKS
A vacuum is pulled on a stream of water, and the vacuum draws the dissolved gas out of solution, removing it from water. There are two basic systems available – tower and membrane. In a vacuum degasser tower, water flows by gravity down through a tower filled with packing as a vacuum is drawn on the tower. The packing in the tower has a very high surface area, disperses the water very effectively, thereby enhancing the removal of O2, CO2 and N2.Performance is further enhanced by using atomizing nozzles as the water enters the tower. In a membrane degasser, water flows across one side of a membrane surface while a vacuum is drawn on the other side. Both types of systems use steam jet eductors or liquid ring pumps to generate the vacuum required.
