Abstract
Abstract An apparatus for the treatment of fluid solutions with an electric field has a vessel for containing the fluids to be treated, the walls of said vessel being made of dielectric material, at least one system of electrodes inside the vessel and at least one system of counter-electrodes outside the vessel for producing electric fields of parallel lines of force and variable strength, to which electric field the fluids are exposed for treatment and purification.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
100 words
An apparatus for treating a liquid comprising: a cylindrically annular vessel having a cylindrical inner wall and a cylindrical outerwall coaxial therewith, both of said walls being of dielectric material; means for introducing a liquid axially into the space between said walls at one axial end of said vessel and for withdrawing said liquid from the other end thereof; a tubular outer electrode surrounding said outer wall; a helical inner strip electrode against the inside of said inner wall; and an electric power source having one terminal connectable to said outer electrode and another terminal connectable to said inner electrode.
Claim 2
Independent Claim

Claim 3
Independent Claim
145 words
An apparatus for treating a liquid comprising: a flat vessel having a pair of spaced planar and substantially parallel walls of dielectric material; a spiral partition in said vessel between said walls defining therein a spiral flow path opening at one end at the outside periphery of said vessel and at the other end at the center of said vessel; means for introducing a liquid into one end of said path and for withdrawing said liquid from the other end thereof; a first radial electrode bar on the outside of said vessel on one of said walls; a second radial electrode bar on the outside of said vessel on the other wall, said electrode bar flanking said flow path over a number of turns; and an electric power source having one terminal connectable to said first electrode and another terminal connectable to said second electrode.
