Abstract
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.
Claims18
An apparatus for removing particles from a nonconductive liquid, comprising:
- (a) first sensing means to sense a first net electrostatic charge on said particles in said liquid and to provide a first output signal indicative of said first net electrostatic charge;
- (b) control and power means to receive said first output signal;
- (c) charging means connected to said control and power means to provide positive and negative electrostatic charging potentials to said particles;
- (d) mixing means connected to said charging means to receive said liquid therefrom and to permit oppositely charged and noncharged ones of said particles to flocculate;
- and
- (e) separating means to remove flocculated said particles from said liquid.
A method of removing particles from a nonconductive liquid, comprising:
- (a) sensing a first net electrostatic charge on said particles in said liquid and providing a first output signal indicative of said first net electrostatic charge;
- (b) in response to said first output signal, providing positive and negative electrostatic charging potentials to said particles;
- (d) permitting oppositely charged and noncharged ones of said particles to flocculate;
- and
- (e) separating flocculated said particles from said liquid.
