The invention relates to the technology of the process of water degassing, in particular, to the technique of vacuum degassing of groundwater to remove dissolved gases: methane, hydrogen sulfide, carbon dioxide, etc. in the field of water treatment with a complex composition of water.

The task of the utility model is the safe operation of water intake facilities and water treatment systems by eliminating the formation of combustible and toxic gases.

The technical result is the qualitative degassing of groundwater due to the use of a two-stage degassing scheme using a hydrocyclone with an air ejector at the first stage and a vacuum degassing column at the second stage.
