摘要
(WO2012150506) A gravity-fed storage water purifier is provided.  The gravity-fed water purifier includes a filtration unit for receiving water.  The filtration unit includes a housing unit, a first membrane cloth layer, a second membrane cloth layer, and a granular biocidal composition layer disposed between the first and second membrane cloth layers.  The first and second membrane cloth layers remove dirt, sand and sediments from the contaminated water, using a depth filtration mechanism.  The granular biocidal composition layer removes bacteria and virus from the contaminated water, through fast leaching of silver ions into the water.  A single storage container is provided that collects the water filtered by the virtue of filtration unit and gravity.  An adsorbent composition is disposed between the storage container and an outlet tap of the storage container.

(WO2012150506) What is claimed is: 1. A gravity-fed storage water purifier, comprising: a filtration unit for receiving unpurified water, the filtration unit comprising: a housing unit; a first membrane cloth layer; a second membrane cloth layer; and a granular biocidal composition layer disposed between the first and second membrane cloth layers; and a storage container, whereby the unpurified water is filtered by virtue of the first and second membrane cloth layers, the granular biocidal composition layer, and gravity, and whereby the filtered water is stored in the storage container. 2. The gravity-fed storage water purifier of claim 1 , wherein the granular biocidal composition layer comprises silver nanoparticles impregnated on organic templated boehmite nanoarchitecture. 3. The gravity-fed storage water purifier of claim 1 , wherein the granular biocidal composition layer comprises silver nanoparticles impregnated on silver nanoparticles impregnated on polyurethane. 4. The gravity-fed storage water purifier of claim 1 , wherein the granular biocidal composition layer comprises silver nanoparticles impregnated on at least one of an oxide and an oxyhydroxide of at least one of aluminum, zinc, manganese, iron, titanium, zirconium, lanthanum, cerium, and silicon. 5. The gravity-fed storage water purifier of claim 1 , wherein the granular biocidal composition layer comprises silver nanoparticles impregnated on silver nanoparticles impregnated on activated carbon. 6. The gravity-fed storage water purifier of claim 1 , wherein the first and second membrane cloth layers are one or more of detachable, washable, attachable, or a combination thereof. 7. The gravity-fed storage water purifier of claim 1 , wherein a size of granules of the granular biocidal composition layer is about 0.3 mm to about 1.5 mm. 8. The gravity-fed storage water purifier of claim 1 , wherein a size of granules of the granular biocidal composition layer is about 0.5 mm to about 1 mm. 9. The gravity-fed storage water purifier of claim 1 , wherein the unpurified water is poured through the filtration unit at a flow rate of about 0.5 L/min to about 5 L/min. 10. The gravity-fed storage water purifier of claim 1 , wherein the unpurified water is poured through the filtration unit at a flow rate of about 1 L/min to about 2 L/min. 11. The gravity-fed storage water purifier of claim 1 , wherein the filtration unit comprises a water inlet connected to a supply of water. 12. The gravity-fed storage water purifier of claim 1 further comprising an outlet tap attached to the storage container for outputting the filtered water. 13. The gravity-fed storage water purifier of claim 12 further comprising an alarm mechanism, wherein the alarm mechanism is configured to be set for retaining the filtered water in the storage container for a predetermined period of time, before it is outputted by way of the outlet tap. 14. The gravity-fed storage water purifier of claim 12 further comprising an adsorbent composition disposed between the storage container and the outlet tap. 15. The gravity-fed storage water purifier of claim 12, wherein the adsorbent composition comprises at least one of an activated carbon, an activated alumina, a silica, a titania, an ion exchange resin, and a halogenated resin. 16. The gravity-fed storage water purifier of claim 1 , wherein the storage container is made of at least one of an engineering plastic, stainless steel, copper, brass, and an earthenware. 17. The gravity-fed storage water purifier of claim 1 , wherein the first and second membrane cloth layers are made of at least one of a cellulose, a polyester, a nylon, and a polypropylene. 18. The gravity-fed storage water purifier of claim 1 , wherein the water purifier further comprises a float valve that regulates flow of water to the water purifier. 19. The gravity-fed storage water purifier of claim 1 , wherein the water purifier is connected to a piped water supply to supply water to the water purifier. 20. The gravity-fed storage water purifier of claim 1 , wherein the filtration unit is used as a water filtration unit for collecting the filtered water in a container. 21. The gravity-fed storage water purifier of claim 18, wherein an alarm mechanism is integrated with the filtration unit. 22. The gravity-fed storage water purifier of claim 18, wherein the container comprises a bottle, can, bucket, drum, carafe, jug, box, tumbler, pitcher, canister, pot, or a combination thereof. 23. The gravity-fed storage water purifier of claim 18, wherein the filtration unit can be integrated with a commercially available water purifier. 24. A gravity-fed storage water purifier, comprising: a filtration unit for receiving water, the filtration unit comprising: a housing unit; a first membrane cloth layer; a second membrane cloth layer; and a granular biocidal composition layer disposed between the first and second membrane cloth layers; a storage container, whereby the water is filtered by virtue of the first and second membrane cloth layers, the granular biocidal composition layer, and gravity, and whereby the filtered water is stored in the storage container; an adsorbent composition; and an outlet tap attached to the storage container, wherein the stored filtered water is output by way of the adsorption composition and through the outlet tap.
