Patent number: 5879546Abstract: A water purification system has a series of sequential operating stations each adapted to remove successively finer suspended or dissolved matter from contaminated water. The sequential steps employed are a pH neutralization step, a particulate precipitation step, a pre-filtration step, a particulate coagulation step and a final filtration step. The particulate coagulation is achieved by means of a novel apparatus for the generation of an especially activated oxygen combined with electrically charged probes for agglomerating the particulate which is filtered in a subsequent station. The initially contaminated water passes through each step in the process and emerges as clean, reusable, water. By employing the process and the system of the invention, the process water is recycled, rather than wasted.Type: GrantFiled: May 20, 1997Date of Patent: March 9, 1999Inventor: Robert M. Burford

Patent number: 5788827Abstract: In a preferred embodiment, an apparatus for removing particles from a nonconductive liquid, including: first sensing apparatus to sense a first net electrostatic charge on the particles in the liquid and to provide a first output signal indicative of the first net electrostatic charge; control and power apparatus to receive the first output signal; charging apparatus connected to the control and power apparatus to provide positive and negative electrostatic charging potentials to the particles; mixing apparatus connected to the charging apparatus to receive the liquid therefrom and to permit oppositely charged and noncharged ones of the particles to flocculate; and separating apparatus to remove flocculated particles from the liquid.Type: GrantFiled: February 10, 1997Date of Patent: August 4, 1998Assignee: M.A.G. Systems, Inc.Inventor: Gerald L. Munson

Patent number: 5783090Abstract: An apparatus for reducing micro-organism concentrations in a liquid having a surface has a portion of a first electrode that is disposed within the liquid. A portion of a second electrode is also disposed within the liquid. The second electrode is spaced apart from the first electrode and, in one embodiment, consists of a copper and silver alloy wherein the ratio of copper to silver is in the range of from 1:1 to 11:3. A direct current power supply, having a positive terminal and a negative terminal, applies an electrical potential between the second electrode and the first electrode, thereby creating an electrical current from the second electrode to the first electrode and thereby liberating copper ions and silver ions from the second electrode into the liquid. In one embodiment, the electrodes are suspended from a floating member. In another embodiment, the electrodes are placed in a porous sheath that is suspended in the liquid.Type: GrantFiled: July 18, 1996Date of Patent: July 21, 1998Inventor: George S. Gleen
