Vacuum deaerators, also known as vacuum degasifiers, use a vertical pressure vessel, multiple vacuum stages and vacuum pumps to continuously remove objectionable gases from liquids
Thermal degasification applies steam heat to remove gasses from a water stream via boiling. It is a physical process that consists of removing the dissolved gases by taking advantage of their insolubility at high temperatures
Membrane degasifiers use a hydrophobic gas permeable membrane to remove dissolved gasses such as oxygen or carbon dioxide from a liquid stream, transferring the gas into a stripping gas or vacuum stream
Chemical degasification uses the injection of chemicals such as sodium bisulfite, hydrazine, or amines to remove dissolved gases from a liquid stream via a chemical reaction
Absorption-based degasification uses a counter-current stripping gas stream to absorb a dissolved gas, removing it from the liquid stream and transferring it to the stripping gas stream. Examples are:
- Packed tower strippers: highest efficiency but prone to fouling
- Sieve tray tower strippers: next highest efficiency; also prone to fouling
- Microbubble strippers (CoStrip): highest fouling resistance
Steam stripping degasification uses high-pressure steam injected at the bottom of a stripping column to remove volatile organic compounds or dissolved gases, such as ammonia, from a liquid stream

Unmatched analytical performance, reliability, and ease of use
Manufacturers need simpler and more efficient analytical testing solutions for quality control and process monitoring. Whether it’s pharmaceutical or semiconductor production, industrial process, environmental, or wastewater monitoring- complex measurements need to be simplified, and compliance cannot be compromised.
