Claims
- 1. An electrolyzer for treating an object liquid comprising:
- a cylindrical anode plate formed as an outer wall and having an inner surface processed with metal, such as platinum, for improved corrosion resistance;
- a cylindrical cathode plate coaxially arranged at a position close to said inner surface of said anode plate;
- two ion exchange membranes coaxially arranged between said anode and cathode plates standing oppositely for functioning as electrically conductive partition diaphragms to control selectivities of ions electrophoretically passing therethrough, one of said two ion exchange membrances being disposed in proximity to said anode plate so as to define an anode chamber, the other of said two ion exchange membranes being disposed in proximity to said cathode plate so as to define a cathode chamber;
- means for feeding acidic liquid into said anode chamber;
- means for feeding alkaline liquid into said cathode chamber;
- means for feeding a solution to be treated into a chamber defined by said two ion exchange membranes;
- each of said chambers being provided with a flange at a discharge side so as to allow each of said liquids and said solution to flow uniformly omnidirectionally towards an outer edge of said flange; and
- said two ion exchange membranes being formed of composite cationic permeable membranes in order to suppress an electrophoretical movement of anions from said chamber defined by said two ion exchange membranes to said anode chamber so that the anode chamber can be protected in the case where anions apt to corrode an anode material are contained in said solution to be treated.
