Potassium hydroxide as is it deal with drug can prevent from to clear up without Black Matrix frame, glass material can be recover. CF recover process make the produce oxyhydrogen base up to 2.7 M, conductivity up to 57mS cm-1 also, research by electrolysis - electrodialysis to get rid of oxyhydrogen, and at the same time, formate potassium hydroxide and chloric acid sodium. It is in experimental for four compartment, it is Pt-Ti / (1)KCl(aq) /C / (2) KOH(aq) /A / (3) wastewater / C / (4) KOH(aq) /Steel, A, C are membrane Asahi AMV and Nafion NX982TX of ion exchange respectively. By the experimental data, it is the concentration, flow velocity, and current density of room 2, 3 and 4 that this system influences . choose the proper experiment condition, operate for 3 hours, the original wastewater diluate 66.97% of current efficiency, 179.74% of recover efficiency of potassium hydroxide and chloric acid sodium 75.4% of efficiency. By the dimensionless groups of the operation variables, we can get 4 equations for current and voltage efficienies.
