Ozonator feed system

Claim 1

Apparatus for treating water with ozone comprising: a. a tank for storing water at normal line pressure, said tank having an inlet near its top, an outlet near its bottom, and an auxiliary inlet near its bottom, b. a by-pass circuit connected between the outlet of said tank and the auxiliary inlet, c. a pump connected in said by-pass circuit for pumping water from the outlet of said tank back into said tank through said auxiliary inlet, said pump being of the positive displacement type and capable of pumping large quantities of gas entrained in the water without becoming airbound, d. means for restricting the flow of water from said tank to said pump enough so that in operation the pump develops a suction at its inlet; e. an ozone generator, and f. means connecting the outlet of said ozone generator to the inlet of said pump so that in operation suction developed by the pump at its inlet draws gas from said generator into siad pump, said pump being the sole source of suction in the apparatus and providing substantially the only impetus drawing gas from the generator.
