Abstract
A dispersion for use with an effluent treatment system, and methods of making and using such a dispersion, whereby the dispersion includes an amount of polymer substantially uniformly dispersed within an aqueous solvent; wherein the dispersion is generated by combining an amount of gas with the amount of polymer and the aqueous solvent, the amount of gas effective to substantially uniformly disperse the amount of polymer within the aqueous solvent.
Claims20
A method of recovering tallow from effluent, comprising:
- providing a dispersion resulting from:
- (i) firstly combining an amount of gas with an aqueous solvent to provide an entrained gas-aqueous solvent mixture;
- (ii) subsequently combining said entrained gas-aqueous solvent mixture with an amount of polymer;
- and
- (iii) mixing said amount of polymer and said entrained gas-aqueous solvent mixture by applying forces consisting of mixing forces generated by said gas in the form of gas bubbles;
- wherein said mixing forces are effective to substantially uniformly disperse said amount of polymer within said aqueous solvent;
- combining said dispersion with said effluent to generate a float comprising said tallow;
- and
- recovering said tallow from said float.
A method of recovering tallow from effluent, comprising:
- providing a dispersion resulting from:
- (i) firstly combining an amount of gas with an aqueous solvent to provide an entrained gas-aqueous solvent mixture;
- (ii) subsequently combining said entrained gas-aqueous solvent mixture with an amount of polymer;
- and
- (iii) mixing said amount of polymer and said entrained gas-aqueous solvent mixture by applying forces comprising mixing forces generated by said gas in the form of gas bubbles;
- wherein said mixing forces are effective to substantially uniformly disperse said amount of polymer within said aqueous solvent;
- combining said dispersion with said effluent to generate a float comprising said tallow;
- and
- recovering said tallow from said float.
A method of separating effluent into solids, water, and a mixture of fats, oils, and greases, comprising:
- providing a dispersion resulting from:
- (i) firstly combining an amount of gas with an aqueous solvent to provide an entrained gas-aqueous solvent mixture;
- (ii) subsequently combining said entrained gas-aqueous solvent mixture with an amount of polymer;
- and
- (iii) mixing said amount of polymer and said entrained gas-aqueous solvent mixture by applying forces consisting of mixing forces generated by said gas in the form of gas bubbles;
- wherein said mixing forces are effective to substantially uniformly disperse said amount of polymer within said aqueous solvent;
- combining said dispersion with said effluent to generate a float comprising said solids, said water, and said mixture of fats, oils, and greases;
- and
- separating said mixture of fats, oils, and greases from said solids and said water.
