Abstract:
1. A portable manually operated batch operation device comprising: a liquid reservoir containing a batch of liquid to be ozonated; a generator producing an ozone containing gas; an apparatus for preventing liquid from entering the ozone generator; a gas pumping system arranged for causing the ozone-containing gas to flow from the ozone generator to a contact region; a controller, responsive to an on/off switch, to operate the ozone generator and the gas pumping system continuously while the device is on; a liquid passageway arranged to receive liquid from said reservoir solely under the force of gravity, said liquid passageway conducting liquid from the liquid reservoir to the contact region, where ozone from the ozone-containing gas dissolves in the liquid; a system for separating undissolved gas from the liquid containing dissolved ozone; a system for preventing ozone in the separated gas from escaping into the atmosphere by passing the separated gas through an ozone reducing material before venting; a controllable delivery system, connected to and receiving liquid containing dissolved ozone from the liquid passageway, to direct the liquid containing dissolved ozone to the point of use, where a rate of flow through the controllable delivery system is adjusted by the user; and a liquid pumping system arranged for receiving liquid containing dissolved ozone from the contact region and causing the liquid containing dissolved ozone to move through the liquid passageway from the liquid reservoir to the controllable delivery system.
