Abstract
Abstract An arrangement is provided for moving at least one aluminum anode with respect to a cathode, to maintain a fixed determined distance between the anode and cathode. An emulsion or contaminated water to be treated is run in the region between the electrodes, and means are provided for preferably running the emulsion or water along the aluminum anode before it reaches the space between the electrodes. The flock is then removed from the resultant flocculated liquid.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
86 words
A method for purifying emulsions and contaminated water, such as water containing oil, with electrolysis, comprising maintaining at least one aluminum anode a determined distance from a cathode with said anode and cathode both being above a vessel, and treating the emulsion or contaminated water by running it into the space between the anode and the cathode to contact these electrodes, whereby flock is produced and said flock and water drop into said vessel, and then separating the flock from the thereby flocculated emulsion or water.
Claim 2
Independent Claim
86 words
A method for purifying emulsions and contaminated water, such as water containing oil, with electrolysis, comprising maintaining at least one aluminum anode a determined distance from a cathode with said anode and cathode both being above a vessel, and treating the emulsion or contaminated water by running it into the space between the anode and the cathode to contact these electrodes, whereby flock is produced and said flock and water drop into said vessel, and then separating the flock from the thereby flocculated emulsion or water.
Claim 3
Dependent Claim
24 words
The method of claim 1 wherein said step of maintaining said aluminum anode a determined distance from said cathode comprises maintaining said distance constant.
Claim 4
Dependent Claim
29 words
The method of claim 1 wherein said step of maintaining said anode a determined distance comprises regulating the distance between said anode and cathode according to a pre-determined program.
Claim 5
Dependent Claim
27 words
The method of claim 1 comprising flowing said emulsion or contaminated water along said anode before it is run into the space between the anode and cathode.
Claim 6
Dependent Claim
24 words
The method of claim 1 wherein said step of maintaining said anode a distance from said cathode comprises maintaining said anode above said cathode.
Claim 7
Dependent Claim
32 words
The method of claim 1 wherein said step of maintaining said anode a determined distance from said cathode comprises feeding an aluminum anode in the form of a thread toward said cathode.
Claim 8
Dependent Claim
18 words
The method of claim 1 wherein said cathode is of stainless steel, in the form of a plate.
Claim 9
Dependent Claim
10 words
The method of claim 1 wherein said cathode is stationary.
Claim 10
Dependent Claim
9 words
The method of claim 1 comprising rotating said cathode.
Claim 11
Dependent Claim
23 words
The method of claim 1 wherein said step of maintaining said distance comprises directing said anode against an insulating plate on said cathode.
Claim 12
Dependent Claim
20 words
The method of claim 1 comprising regulating said distance in accordance with the flow density of the material being treated.
Claim 13
Dependent Claim
18 words
The method of claim 1 comprising regulating said distance in accordance with the amount of liquid being treated.
Claim 14
Dependent Claim
42 words
The method of claim 1 comprising applying a low voltage direct current to said anode and cathode to cause a flow therebetween of the order of 1 ampere, whereby the electric consumption is below 1 Watt per liter of liquid being treated.
Claim 15
Dependent Claim
32 words
The method of claim 1 wherein said step of maintaining said anode a determined distance from said cathode comprises feeding an aluminum anode in the form of a plate toward said cathode.
Claim 16
Dependent Claim
18 words
The method of claim 1 wherein said cathode is of stainless steel in the form of a drum.
