  • Publication number: 20160046512
    Abstract: 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.

  • Publication number: 20140319069
    Abstract: 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.

  • Publication number: 20140124454
    Abstract: A water treatment composition includes a water soluble film formed into a sealed pouch. The pouch contains a composite of a phosphate removing substance, a polymer flocculant, or an enzyme, or any combination. The phosphate removing substance, the polymer flocculant, and the enzyme are bound to each other within the composite. The pouch is added to a body of water. The pouch dissolves to release the compounds and treat the water.

  • Patent number: 8357787
    Abstract: 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.

  • Patent number: 8281515
    Abstract: Methods for increasing the growth and biomass of algae and algae lipids by growing the algae in the presence of a polycationic substance such as soluble or insoluble chitosan and/or chitin are disclosed. Also disclosed are methods of harvesting algae from an aqueous environment by growing the algae in aggregated clumps and/or mats (formed by the inclusion of soluble or insoluble chitosan and/or chitin or other polycationic or cationic substances) that can be easily removed from the aqueous environment either by filtration, surface skimming, and/or growing in a porous containment device, such as a natural or synthetic fabric, and removing the fabric from the aqueous environment containing the aggregated algae. The methods disclosed have direct applications in biofuel and energy production, agricultural feedstock production, nutrient production, greenhouse gas reduction, removal of microconstituents from water, and water reclamation.
