Abstract
A deaeration system is disclosed. A preliminary filtration stage is configured to filter particles from and nucleate gas in a fluid stream to create a filtered fluid stream. A primary filtration stage is downstream of the preliminary filtration stage configured to separate the filtered fluid stream into a first liquid stream and an air cavity concentrate stream. A secondary filtration stage is configured to receive the air cavity concentrate stream and separate the air cavity concentrate stream into a second liquid stream and a gas stream.
