イオン交換膜電気透析系を活用した実用的な飲料水用新殺菌法(II)工学的解析

Abstract
To develop a new disinfection method for drinking water, estimations of electric current densities and consumed electric powers have been investigated for a practical disinfection electrodialysis system with cation- and anion- exchange membranes under various conditions. Equations of the current densities and consumed electric powers have been derived by applying an equivalent electric circuit equation and a process design equation to the unit cell of the electrodialysis system. The calculated val ues were compared with the experimental values obtained from the practical disinfection experiments using Tama river sample solution added with various amounts of sodium chloride. It was found that the calculated values are almost equal to the experimental ones, i. e., the electric current densities and consumed electric powers necessary for perfect disinfection can be estimated from the equations.
