Abstract
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.
