Abstract:
A method of quickly inverting a flocculant-containing emulsion for solids and liquid separation in aqueous slurries, the method comprising:(a) dosing water with an effective flocculating amount of least one water-in-oil water emulsion comprising at least one flocculant, at least one hydrophilic surfactant and at least one high terpene content natural oil, said surfactant being present in the emulsion at a concentration of from about 1 to about 10 percent, by weight; (b) subjecting the water and the emulsion-containing water to high shear, comprising a turbulent reverse flow, at a sufficient pressure and for a sufficient time for the at least one emulsion to invert and release the at least one flocculant into the water; and (c) adding the released at least one flocculant into an aqueous slurry for separation of solids from water in the slurry.
