Abstract: Coatings for reducing or preventing fouling of surfaces are provided. In some embodiments, the coating comprises a silane compound, a siloxane compound, a phosphonate compound, a silicone polymer such as PDMS (polydimethylsiloxane), or a combination of silane-siloxane-phosphonate-PDMS in various molecular configurations in single monolayer and overlay assemblies. Also provided are related methods for forming the coating as well as coated substrates such as heat exchangers. Embodiments of the coatings are highly hydrophobic with high contact angles and the coated substrates may be used in a variety of industrial applications that require handling of oil-in-water emulsions, process water and produced water from various process operations, including Steam Assisted Gravity Drainage (SAGD) operations.

Abstract: 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.
