Method and device for aerating a liquid with a gas

摘要

The method for enriching a liquid with a gas, in particular, for purposes of separating interfering substances from suspensions by flotation involves jetting of the liquid into a gas volume. As a result, a part of the gas volume is sucked into the jet and is thoroughly mixed with the liquid during its further transport. Also claimed is an apparatus for implementation of the method. It comprises a nozzle (11) located at the entry of an injector unit (10) inside a pressure vessel (9) with liquid and gas spaces.
