Abstract

PURPOSE:To prevent scale components from accumulating in ion exchange membrane, by, in manufacture of Cl2 used in treatment of drinking water or sewage through electrolysis of brine in a two-chamber type electrolytic cell with cation exchange membrane, drawing off NaOH soln. contained in the cell immediately after the current is turned off at the time of regular suspension of the electrolysis. CONSTITUTION:In production of NaOH or Cl2, for use in treatment of drinking water or sewage, by charging impure brine contg. 0.03-0.2 g. total quantity of scale components Ca<2+>, Mg<2+>, per 100g. NaCl to a two-chamber type electrolytic cell with cation exchange membrane, the electrolytic cell is operated as follows in order to dissolve and remove the scale component, and a small amount of scale deposited, in the membrane: At the time of regular suspension of electrolysis, NaOH soln. is drawn off immediately after the turn off of the current, hereafter aq. NaCl soln. of pH 1-4 is circulated through the anodic chamber for 2-60 min. Regular suspension of the electrolysis is conducted once in 48-72 hr. and the circulation of brine is carried out for 2-60 min.
