ABSTRACT:
A static diffuser for use within the water tank of an ozonator system. The diffuser comprises a depending water pipe into which water is fed under pressure by an external pump. The lower end of the pipe flares outward and has an internal fixed cone which combines with the flared end of the pipe to provide an annular laterally directed water discharge. The annular discharge includes angularly directed vanes to enhance the water discharge and assist in forming a high velocity outwardly directed circular sheet of water. The pipe is surrounded, in spaced relation, by a shroud through which the ozone is introduced. The shroud is provided with an annular slot outward of the pipe discharge, the shape of the shroud at the slot forming a modified 360.degree. circular venturi whereby the discharging high velocity sheet of water creates a negative pressure drawing the ozone therewith into the surrounding body of water for a ozonation thereof.
