Abstract (en)
[origin: WO9914163A1] The object of the present invention is a water treatment apparatus (10) that integrates an ozone generator (18), CT and storage tanks and a microcontroller (14). Raw water from a municipal or private water supply is passed through a pretreatment filter (54) to the CT chamber where ozone is dissolved in the water to kill bacteria, viruses and other microorganism. Ozone is manufactured in an ozone generator (18), pumped to the CT chamber where it is forced through a diffuser (38) and past a sonic wave generator (40) to increase the mass transfer efficiency. A degassing and ozone destruct mechanism (42) removes ozone enriched air from the CT chamber and destroys the ozone prior to release of the air into the environment. Water in the CT chamber is treated at a specified level of ozone concentration for a predetermined period of time to assure that microorganisms are killed. Treated water is pumped into biologically static storage tank which is protected from airborne contaminants by a blanket of ozone enriched air gap (84) in the blanket, to the storage tank where it is held for dispensing. It can be recirculated into the CT chamber for retreatment when required due to recontamination.
