Patent number: 10040710Abstract: 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.Type: GrantFiled: May 15, 2015Date of Patent: August 7, 2018Assignee: Dober Chemical CorporationInventors: Everett J. Nichols, James R. Scott, Jeffrey F. Williams, Yongjun Chen

Patent number: 8357787Abstract: 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.Type: GrantFiled: April 5, 2012Date of Patent: January 22, 2013Assignee: HaloSource, Inc.Inventors: Everett J.
