Abstract
A device for gassing a liquid, particularly for membrane facilities used in immersion operation, has a gas supply channel and at least one gas lance from which a gas flow exits in gassing operation. The gas lance is connected to the gas supply channel via at least one connection channel including a first mouth area on the side of the gas lance and a second mouth area on the side of the gas supply channel and generating as a throttle a flow pressure loss of the gas flow entering the gas lance. Below the first mouth area an extension section is provided, which adjoins the gas lance and has an opening below the first mouth area.
