Abstract:
1. A method for removing contaminants from a contaminated fluid flow, comprising the steps of: providing a cavitation and electrocoagulation reactor having a cylindrical anode coaxially disposed within a hollow cylindrical cathode defining an annular interelectrode cap therebetween; pumping the contaminated fluid flow through the annular interelectrode gap; processing the contaminated fluid flow in the cavitation and electrocoagulation reactor, wherein the processing step includes repeatedly generating and collapsing hydrodynamic cavitation bubbles in the contaminated fluid flow while in the annular interelectrode gap, and simultaneously exposing the contaminated fluid flow to an applied electric field generated by the cathode and the anode; forming radicals of the contaminated fluid flow and its constituents; coagulating the contaminants in the contaminated fluid flow; and separating the coagulated contaminants from the contaminated fluid flow resulting in a purified fluid flow.
