Abstract:
A method for electrostatic treatment of a liquid comprising:(a) an electrode comprising a base piece, a cylindrical conductor extending from the base piece, the conductor extension from the base piece defining an outer surface, a dielectric layer in contact with the entire outer surface thereby forming a liquid tight seal, and electrical connections from the conductor to a positive pole of a direct current power supply; (b) a conduit having the base piece sealingly mounted thereon and adapted to support the base piece so that the electrode protrudes into liquid in the conduit, the conduit further comprising an electrical connection adapted to cause at least a portion of the conduit to act as a negative pole as to the direct current power supply; (c) flowing liquid in the conduit past the dielectric layer and applying across the conduit and electrode a voltage greater than or equal to about 10,000 volts; and (d) the dielectric layer comprises a polymer having a dielectric constant of greater than about 3.6.
