Patent number: 6485651Abstract: This invention is directed to methods for quickly inverting and dispersing a flocculant in an aqueous slurry to achieve settlement of solids and clarification of the slurry water. In particular, this invention relates to methods for quickly inverting a flocculant-containing emulsion in-line without significantly destabilizing the emulsion. The methods comprise dosing water with at least one water-in-oil emulsion containing at least one of a flocculent polymer and a hydrophilic surfactant and subjecting the water and emulsion to a high shear, turbulent reverse flow, such that the combination of the surfactant and shear synergistically inverts the emulsion, so the flocculant may be directly injected into the slurry. In an alternative embodiment, the emulsion is fed directly to the slurry to be treated and subjected to high shear, such that the emulsion inverts in situ, releasing the flocculant into the slurry for solids/liquid separation.Type: GrantFiled: March 28, 2001Date of Patent: November 26, 2002Assignee: Ondeo Nalco CompanyInventor: Merle L. Branning
