A liquid treatment system receives untreated liquid from a pressurized sourc e and outputs treated liquid on demand. An ozone containing gas from a generator is combined with untreated liquid to accomplish the desired treatment before the liquid is output; and the necessary operations include pumping, venting, a demand even t switch, and a control system to accomplish the necessary functions. A valued liquid passageway conducts untreated liquid to a contact region, accumulated gas is vented from the system. A demand event can be manual operation of an output switch or manual operation of an outflow valve that causes a liquid level change within the system. Treated liquid outflow can occur by gravity, as a passive outflow in response to opening an inflow valve, and as an active outflow driven by a pump.
