| 20120199540 | FILTER COMPRISING MULTIPLE HALOGENS AND CHITOSAN - The water treatment systems may generally comprise multiple halogens and chitosan or derivatives thereof as well as methods of making and using the same. A water treatment system to provide potable water may generally comprise an inlet in fluid communication with an outlet, a halogen release system intermediate the inlet and the outlet, and a halogenated chitosan intermediate the halogen release system and the outlet. The system may comprise a scavenger barrier intermediate the halogenated chitosan and the outlet. The halogen release system may comprise a first halogen having a first oxidizing potential. The halogenated chitosan may comprise a second halogen having a second oxidizing potential. The second oxidizing potential is greater than the first oxidizing potential. | 08-09-2012 |
| 20110226706 | FILTER COMPRISING A HALOGEN RELEASE SYSTEM AND CHITOSAN - A filter to provide potable water may generally comprise an inlet in fluid communication with an outlet, a halogen release system intermediate the inlet and the outlet, a filter material comprising chitosan or a derivative thereof intermediate the halogen release system and the outlet, and a scavenger barrier intermediate the filter material and the outlet. The filter material may comprise a chitosan-halogen complex. The filter material is capable of regeneration during periods of stagnation. The filter may have a Log reduction value for viruses of at least 4 and a Log reduction value for bacteria of at least 6. | 09-22-2011 |
| 20100133194 | WATER TREATMENT SYSTEMS WITH DUAL PURPOSE ION EXCHANGE RESIN - A low pressure point-of-use water treatment system may generally comprise at least one inlet port in fluid communication with at least one outlet port to establish a fluid pathway therethrough; an iodinated resin intermediate the at least one inlet port and at least on outlet port, wherein the iodinated resin transfers iodine into the fluid pathway for a volume of water corresponding to an effective life of the iodinated resin; and an ion exchange resin intermediate the iodinated resin and the at least one outlet port, wherein the ion exchange resin removes at least a portion of the iodine transferred by the iodinated resin into the fluid pathway for a volume of water corresponding to a breakthrough point as measured by iodide leakage; and wherein the ion exchange resin inactivates contaminants in the fluid pathway as the iodinated resin nears the end of its effective life. | 06-03-2010 |
