An apparatus for the purification of water contaminated by micro-organisms and chemicals by means of a three stage process is taught. The apparatus consists of a prefiltration stage, an ozonation stage, and a post filtration stage. The contaminated water is initially drawn from a reservoir through a filter through a bed consisting of a porous media, calcium bentonite, zeolite, activated carbon and a second porous media. The filtered water is then passed into a ozonation chamber wherein gaseous ozone is introduced so as to oxidize contaminants. The reduction/oxidation condition in the ozonation chamber serve to control the cycle time. Once the water is disinfected it is passed through a second filter consisting of a porous media and activated carbon before being dispensed into a clean water carafe.

[ What is claimed is:] [10.]10. A domestic apparatus for treating water on a batch basis comprising:(a) an untreated water storage container for receiving and storing water to be treated;(b) a first pump positioned downstream from the untreated water storage container for transporting water from the untreated water storage container to an ozone contact chamber;(c) a pre-filter;(d) the ozone contact chamber positioned downstream from the pre-filter, the ozone contact chamber receiving water to be treated;(e) an ozone supply for supplying ozone to the ozone contact chamber and contacting the water in the ozone contact chamber to treat the water;(f) a post-filter for filtering residual ozone and contaminants from the treated water;(g) a treated water storage container positioned downstream from the ozone contact chamber for storing the treated water;(h) a pump positioned downstream from the ozone contact chamber for transporting water from the ozone contact chamber to the treated water storage container; and,(i) a sensor for measuring the quality of the treated water and an exit port for disposing of treated water which is not of a preset quality.
