Electrolytic treatment of liquids

A method of purifying aqueous solutions, comprising the steps of:

• passing said aqueous solution along an inner insulator wrapped around a centrally located solid rod, wherein said aqueous solution is in contact with the external surface of said centrally located solid rod and the internal surface of an inner tube;
• passing said aqueous solution along an outer insulator wrapped around said inner tube, wherein said aqueous solution is in contact with the external surface of said inner tube and the internal surface of an outer tube;
• connecting one terminal of a DC voltage source to said solid rod and said outer tube;
• connecting another terminal of said DC voltage source to said inner tube;
• applying a voltage across said solid rod, and said inner and outer tubes from said DC voltage source;
• and thereafter
• removing suspended materials and dissolved solids from said aqueous solution.
