<p>Apparatus for supplying air into a liquid can be used as an aeration apparatus for a biochemical waste water treatment system operating according to an activated sludge process, for example, or as an air bubble generator to be used in a solid particle flotation system. A liquid in a tank is circulated by a pump. An air intake device is disposed in a suction pipe connected to the pump. The air withdrawn by the air intake device is mixed and agitated with the liquid in the pump, whereby minute air bubbles are distributed throughout the liquid. The liquid containing air bubbles is fed from the pump to an injector disposed within the tank, and ejected thereby into the tank in the form of jet water streams.</p> |
