    摘要： The invention relates to a two-stage design for a water purification system, with water to be purified first passing through a first stage containing particulate filtration media, and a second stage containing a porous filtration block. The particulate filtration media can be the same as, or different from, material included in the porous block. Either material may be any material that removes contaminants from water by, e.g., absorption, adsorption, ion exchange, sequestration, or other mechanism, or any combination of these.

    摘要： An amorphous potassium aluminosilicate filtration media which may be mixed with activated carbon filters water to remove oxygen, chlorines, hardness, alkalinity, ammonia, hydrogen, hydrogen sulfide, sodium sulfite and other contaminants. The particular sodium aluminosilicate is a porous amorphous material formed under ultraviolet light or sunlight to produce pore sizes of 60 Å to 250 Å at ambient temperatures (20° C.-35° C.) and low relative humidity (5%-20%). The media is initially formed as a microporous primarily amorphous gel containing Na2O, Al2O3, SiO2 and H2O. The sodium therein is displaced by potassium, whereby the filter removes impurities from water without introducing sodium. The potassium aluminosilicate may be a second stage filter to a first stage filter composed of a strong base anion media charged with potassium carbonate and/or bicarbonate. The filtration media may be used in any type gravity filter including that in an inverted bottle type dispenser for filtering water the flowing from the bottle to the spigot and also filtering air which bubbles back into the bottle in response to opening the spigot. The media as blended with activated carbon may be composed of molded particles having diameters from 1 to 100 microns and preferably 1-20 microns with an average diameter of about 10 microns. It also may be blended with zirconium oxide without carbon for reducing anion and cation species from drinking water.

    摘要： A potassium aluminosilicate is used as a filtration media for filtering water to remove dissolved oxygen, hardness and other dissolved gases and impurities from the water, such as ammonia, hydrogen, hydrogen sulfide and sodium sulfite. The particular potassium aluminosilicate is a mesoporous amorphous material formed under ultraviolet light or sunlight to produce pore sizes of 60 .ANG. to 250 .ANG. at ambient temperatures (20.degree. C.-35.degree. C.) and in a low relative humidity (5%-20%). Sodium may be displaced in the zeolite media by potassium so that advantageous removal of impurities in the water occurs without introducing sodium into the water. The potassium aluminosilicate of the present invention may be used as a second stage filter to a first stage filter composed of strong base anion media charge with potassium carbonate or bicarbonate.

    摘要： A fluid purification system capable of removing contaminants from significant volumes of fluids under low pressure conditions and at reasonable flow rates is provided. The system comprises a first fluid purification media comprising a rigid porous purification block. The rigid porous purification block includes a longitudinal first surface; a longitudinal second surface disposed inside the longitudinal first surface; and a porous high density polymer disposed between the longitudinal first surface and the longitudinal second surface. The system further includes a second fluid purification media, comprising a fibrous, nonwoven fabric disposed adjacent to the first surface of the first fluid purification media, the second surface of the first purification media, or both.
