    摘要： Compositions for water treatment are provided. In some embodiments, the composition comprises: a cationic polyacrylamide-type polymer having a charge density of about 10% to about 40% and a molecular weight of about 600×104 g/gmol to about 900×104 g/gmol; and a cationic surfactant, the surfactant comprising an alkyl quaternary ammonium salt. Also provided are related methods and kits for treating wastewater with dispersed and dissolved organic matters and oils. Embodiments of the compositions, methods, and kits can be used to treat oil-in-water emulsions, produced water, and process water containing dispersed and/or dissolved organic matter such as hydrocarbons from various process industries including Steam Assisted Gravity Drainage (SAGD) oil operations.

    摘要： Compositions and methods are described to accomplish the in-situ remediation of contaminated groundwater and soil. Such compositions may comprise oil droplets, a water-miscible non-aqueous liquid phase, and one or more solid particulates. The oil droplets and the solid particulates are contained within the water-miscible non-aqueous liquid phase. The solid particulates may comprise one or more of zero valent iron, iron silicide, ferrosilicon, magnetite, particulate carbon, iron/carbon composites, calcium carbonate, and palladium. The solid particulates may comprise zero valent iron particles. The water-miscible non-aqueous liquid phase may be glycerol and the composition may be an oil-in-glycerol emulsion. Exemplary methods of preparing a groundwater remediation product comprise mixing oil droplets, a water-miscible non-aqueous liquid phase, and solid particulates contained in the water-miscible non-aqueous liquid phase to form a composition. The composition may be diluted with water in a mass ratio of 0 to 99% water such that the composition becomes an aqueous product suitable for applying to groundwater and soil.
