The anode of the present invention is manufactured by processes including a titanium etching step, a drying step, a surface-coating step, and a final firing step. The anode manufactured in accordance with the method of the present invention exhibits high efficiency in TRO generation and excellent durability in seawater, and has a shape for improving current efficiency.
The present invention relates to a base metal structure for a mesh-type dimensionally stable anode for water treatment, wherein a plurality of anodes to be used in a water treatment device using electrolysis are formed into a module. More particularly, the present invention relates to a base metal structure adopting a perforating system for manufacturing a dimensionally stable anode, wherein the mesh of the anode is processed by perforating a plate, and a current-applying unit uses the plate. The current-applying unit is formed horizontally or vertically to a reaction unit, and processed.
