Abstract: The Water Ozonating System can take several forms. Generically, the system incorporates at least the following: a water inlet means, a water storage tank, a device for introducing ozone into the water in the storage tank, and a device for dispensing water from the storage tank. A unique and particularly advantageous feature of the Water Ozonating System is that the ozonated water is kept entirely within a closed system until it is dispensed to the user. This maintains ozone in the water and in its active state (i.e., with its decontaminating and sterilizing effect). The system provides storage tank of ozone within the effluent water. This invention has many applications but not limited to the following: residential and office water purification; supermarket produce, vegetable, meat, poultry and fish, rinsing; dental operatory procedures; laboratories and commercial rinse water functions.
