Method and apparatus for removing contaminants from an aqueous fluid
First Claim
1. A method for removing contaminants from an aqueous fluid stream comprising:
- providing a housing containing a plurality of treatment plates, each of said plurality of treatment plates being positioned within said housing such that each of said treatment plates is affixed to an end of said housing and is shorter than said housing such that a gap exists between each of said treatment plates and an opposing end of said housing, wherein alternate iterations of said treatment plates are affixed to alternate ends of said housing thereby causing said gaps left by alternate treatment plates to exist at alternate ends of said housing;
providing electrical current to said treatment plates such that iterations of said treatment plates are alternately cathodes and anodes; and
introducing said aqueous fluid stream into the top of said housing such that said aqueous fluid stream flows past each of said treatment plates before exiting at the bottom of said housing.

Abstract
A method and apparatus for the removal of both suspended and dissolved contaminants in a fluid stream, including but not limited to heavy metals, organics, inorganics, hydrocarbons and others. The method combines passing an aqueous fluid stream through an electromagnetic field, an ozone/oxygen venturi injector for oxidation and through a horizontal flow and vertical fall within a horizontal plate maze unit of alternately electrically charged plates. The plates are charged alternately to be cathodes and anodes, respectively. A framework to mount and support membranes, dividers or separators, as may be required to enhance special treatment of the fluid stream, is optionally provided.

6. A method for removing contaminants from an aqueous fluid stream comprising:
-
(a) introducing bubbles into said fluid stream, said bubbles being comprised of oxygen, ozone, or a combination thereof; (b) passing said fluid stream through a fluid channel, said fluid channel having at least one anode on one side thereof and at least one cathode on another side thereof; and (c) passing said fluid stream through a magnetic field. - View Dependent Claims (7, 8, 9, 10)

11. An apparatus for removing contaminants from an aqueous fluid stream comprising:
-
a source of electrical current connected to a plurality of treatment plates; a source of ozone for introducing ozone into said aqueous fluid stream in the form of bubbles; a housing, said housing having at least first and second opposing sidewalls, said at least first and second opposing sidewalls further comprising a plurality of grooves imparted into said sidewalls; wherein each of said plurality of treatment plates is inserted into at least one of said sidewall grooves, said treatment plates being of a length slightly short of a distance between said at least first and second opposing sidewalls, said plurality of treatment plates further being arranged in a staggered manner such that a first subset plurality of said plurality of treatment plates comprise cathode plates and wherein a second subset plurality of said plurality of treatment plates comprise anode plates;
said plurality of treatment plates defining at least one flow channel, wherein a pair of opposing treatment plates define said flow channel for introducing said aqueous fluid stream there into. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
