  • Double funnel device for oxygenating sewage
    Patent number: 3968086
    Abstract: A method and an apparatus for continuously aerating sewage is in the form of a gun with a nozzle for producing a jet of oxygen-containing gas and a plurality of funnels converging downstream and arranged downstream of the nozzle and of one another so as to gradually mix the gas into the liquid and to dispense the resultant mixture into more liquid. The result is that the liquid issuing from the gun does so with an even oxygen content and velocity profile, and that any bubbles which may exist are very small and cannot easily coalesce.
