International ClassB01F 003/04AbstractA method and apparatus for aerating an aqueous solution is disclosed comprising a vortex cylinder for receiving an aqueous solution stream under pressure. The aqueous solution stream is tangentially injected into the vortex cylinder forming a descending swirling vortex of aqueous solution. The swirling vortex develops a negative pressure zone for drawing air into the vortex through an air intake tube open to ambient pressure. The air and aqueous solution are mixed in a mixing chamber for supersaturating the aqueous solution with dissolved oxygen. | |
