Abstract
A method for removing a solute from a fluid using magnetically conditioned coagulation includes magnetically conditioning the fluid by applying a conditioning magnetic field to enhance the precipitation of solute particles for coagulation; adding a coagulant to the fluid before, during, or after application of the conditioning magnetic field to coagulate the increased available solute particles to form colloids; and collecting the colloids for removal from the fluid.
Claims89
A method of removing a solute from a fluid, the method comprising:
- applying a conditioning magnetic field before flocculation to a fluid which includes a substance dissolved therein in the state of a solute and magnetically enhancing the change of the form of the substance from a dissolved state, to a non-dissolved state, namely a particulate form state, to thereby enhance precipitation of the solute for coagulation, wherein the conditioning magnetic field has an average flux density in the range of greater than 0.2 Tesla to 6.0 Tesla and a field gradient in the range of greater than 60 Tesla/meter to 2000 Tesla/meter, and is parallel to the direction of fluid flow;
- adding a coagulant to the fluid proximate the application of the conditioning magnetic field to further effect a transformation of the magnetically conditioned solute from a dissolved state to a non-dissolved, particulate state forming colloids, and to destabilize the colloidal suspension of said particulates by reducing any charge on the surfaces of said particles responsible for repulsion between them;
- and
- collecting the colloids for removal from the fluid including the steps of adding a magnetic seed to the fluid and adding a flocculent to the fluid to form flocs.
