| 20110309294 | FORMULATIONS AND METHODS FOR SOLID CHITOSAN-CONTAINING BLENDS - Chitosan-containing blends and methods of dissolving and using chitosan are disclosed. A blend includes a solid acid or a solid agent that generates a proton in situ in the presence of water mixed together with a dry solid chitosan, and may optionally contain other components. The blends are in a dry, free-flowing, particulate form. Methods of dissolving a blend typically comprise adding a quantity of the blend to a low volume of water and mixing until the chitosan and solid acid or solid agent are dissolved and then further diluting this mixture by the addition of water, or used as-is. Devices containing the blends are also described along with methods of using the devices, such as for controlled release of solubilized chitosan in a body of water, such as a stream, containing impurities (e.g., particles, sediment, or suspended matter or dissolved substances) to cause flocculation or precipitation of such impurities. | 12-22-2011 |
| 20110006013 | METHOD FOR THE REMOVAL OF SUBMICRON PARTICULATES FROM CHLORINATED WATER BY SEQUENTIALLY ADDING A CATIONIC POLYMER FOLLOWED BY ADDING AN ANIONIC POLYMER - A method for removing submicron colloidal particulates, such as hydrocarbons, from water. The method includes first adding a soluble, cationic polymer, such as chitosan, a salt, or solution of chitosan to water containing the submicron particulates and a halogenating agent, followed by adding a soluble, anionic polymer or anionic salt to the water. The resulting flocs are filtered to remove the submicron particulates. | 01-13-2011 |
| 20110000854 | USE OF A DUAL POLYMER SYSTEM FOR ENHANCED WATER RECOVERY AND IMPROVED SEPARATION OF SUSPENDED SOLIDS AND OTHER SUBSTANCES FROM AN AQUEOUS MEDIA - A method uses anionic and cationic polymers added in, any order or simultaneously, to aqueous media for the removal of substances. The sequential addition of the two biopolymers, anionic xanthan, followed by cationic chitosan, causes the rapid formation of very large and cohesive fibrillar aggregates that may exhibit high solids to liquid ratios and that quickly settle out from the aqueous media. The aqueous media can be easily separated from the large fibrillar aggregates by settling under gravity or by filtration through a porous containment device, such as a synthetic or non-synthetic woven or non-woven fabric including a geotextile fabric or a solid containment device containing a solid mesh screen. | 01-06-2011 |
| 20090239907 | METHODS AND COMPOSITIONS FOR TREATING FISH DISEASES - Therapeutic and prophylactic treatments of aquatic species and aquatic diseases through the controlled introduction of a heterocyclic N-halamine into an aquatic habitat. | 09-24-2009 |
| 20090214610 | BENZOIC ACID CONTAINING COMPOSITION FOR MAINTAINING HYDANTOINYLATED POLYMERS IN A BIOCIDALLY ACTIVE STATE - A tablet includes benzoic acid and trichloroisocyanuric acid. The tablet provides free available chlorine in water to maintain an N-halamine-containing polymer biocidal, without rendering the water undrinkable from high chlorine content. The tablet may be used in a water purification device having a cartridge containing an N-halamine polymer to provide safe drinking water. | 08-27-2009 |
| 20080202992 | PURIFIER INSERT WITH A TABLET DISPENSER AND INDICATOR - A water purifier that can be placed between an upper canister and a lower canister. The upper canister may include filters. Unfiltered water placed in the upper canister drains by gravity through the filters and water purifier into the lower canister. The water purifier includes a dispenser, a purifying media, and an indicator. Filtered, but unpurified, water passes from the upper canister into the water purifier, which houses the dispenser in which a material containing a chlorine and/or bromine compound is located. As water contacts the material, halogen is eluted to the filtered water. The purifying media contacts the unpurified water with halogen. The purifying media binds with the halogen, thereby maintaining the activity of the purifying media to purify the unpurified water. The water purifier may include an indicator to indicate when the material needs replacing. | 08-28-2008 |
