    摘要: A method for enhancing filtration performance in separating solids from liquids in an aqueous dispersion comprising a solids phase and a liquid phase in a two step process having a physical separation step and a filtration step comprising adding at least one filtration aid promoter and at least one synthetic polymer to the aqueous dispersion during and/or before the physical separation step resulting in concentrate and filtering the concentrate. The method may be applied in mining operations for dewatering mining slurry. Also, a composition applied in such method comprising at least one filtration aid promoter and at least one synthetic polymer. The filtration aid promoter comprises natural polymers, semi-natural polymers, coagulants and combinations thereof.

    摘要: Scale control agents comprising organic phosphonates, either alone or in mixtures with inorganic phosphonates and also optionally polymers, such as low molecular weight polymeric dispersants. The scale control agents may be applied to inhibit scale formation or deposition in highly acidic aqueous systems by adding these agents to such systems in amounts effective to inhibit metal sulfate scale formation.
