摘要： PROBLEM TO BE SOLVED: To provide a method for collecting ink in a process of deinking of used paper more efficiently with a high cost-performance; a method for producing pulp and paper having both an excellent brightness and a low effective residual ink concentration, ERIC; a method for improving qualities of the final pulp and paper and yields of pulp and paper in a floating/cleaning combination deinking process and a cleaning deinking process; and an improved method for collecting and removing ink in a low alkaline and/or neutral condition.SOLUTION: The method uses a deinking composition including hydrophobically modified inorganic particles, MIP, in order to improve efficiency of ink collection. The deinking composition includes a hydrophobic MIP substance, a nonionic surfactant, and a fatty acid, or a mixture thereof. The improved ink collection performance can bring about a high quality and/or a high yield deinked pulp having an excellent brightness and an effective residual ink concentration, ERIC, value.

摘要： The present embodiments generally relate to methods and compositions comprising one or more polymers which gradually increase in charge, thereby providing for an increase in viscosity in an aqueous solution or aqueous composition, such as when present in a desired aqueous environment. Use of such compositions and methods comprising one or more polymers which gradually increase in charge, thereby providing for an increase in viscosity in an aqueous solution or aqueous composition during enhanced oil recovery may result in an increase in oil production relative to methods and/or compositions which do not comprise one or more polymers which gradually increase in charge, thereby providing for an increase in viscosity in an aqueous solution or aqueous composition.

摘要： Methods and apparatus or systems useful in the treatment of tailings are provided, e.g., oil sands tailings, and mature fine tailings. These methods and apparatus or system used therein comprise the combined use of electrocoagulation and chemical flocculation effected using one or more flocculants. The combined use of electrocoagulation and chemical flocculation in these methods and using these apparatus or system results in improvements such as improved removal of fine, slow settling clay particles, persistent contaminants, and/or residual bitumen; lower solids content, lower turbidity, and lower carbon oxygen demand ("COD").

摘要： The present embodiments generally relate to the treatment of produced water such as produced water resulting from an industrial process such as one involving the use of copious amounts of water and the addition of one or more polymers such as viscosifying or thickening polymers, in particular enhanced oil recovery processes or another processes resulting in polymer flooded produced water. These treatment methods include contacting the produced water with one or more reducing agents and one or more metals, wherein said treatment may result in a reduction of the viscosity of said produced water and/or the degradation of polymers which are contained therein.
