Compositions and methods for destroying chemical and biological agents such as toxins and bacteria are provided wherein the substance to be destroyed is contacted with finely divided metal oxide nanoparticles. The metal oxide nanoparticles are coated with a material selected from the group consisting of surfactants, waxes, oils, silyls, synthetic and natural polymers, resins, and mixtures thereof. The coatings are selected for their tendency to exclude water while not excluding the target compound or adsorbates. The desired metal oxide nanoparticles can be pressed into pellets for use when a powder is not feasible. Preferred metal oxides for the methods include MgO, SrO, BaO, CaO, TiO2, ZrO2, FeO, V2O3, V2O5, Mn2O3, Fe2O3, NiO, CuO, Al2O3, SiO2, ZnO, Ag2O, the corresponding hydroxides of the foregoing, and mixtures thereof.

A water treatment tank for use with water purification apparatus including an ultra-violet lamp within an encapsulating sleeve onto which incoming water is directed to provide a thin laminar flow about the bulb. The lower compartment has cooling coils about the walls for cooling the water therein relative to the water in the upper compartment. A surrounding sleeve may be located intermediate the encapsulating sleeve and an outer vessel in the tank. A leak detector is located in the encapsulating sleeve. The leak detector and outer vessel are believed to provide safety to users in the event of internal breakage in the tank. A reflective surface is also utilized to direct UV light into portions of the faucets formerly obscured from UV treatment. The faucets preferably provide self-sanitizing capability and an information center selectively displays time until next service, cost savings over bottled water and information related to the dispenser.
