ABSTRACT:
An apparatus for treating a liquid by electrochemical ion exchange comprises a flow channel (34) in which are arranged a cation-responsive ion exchange electrode (38) side by side with an anion-responsive ion exchange electrode (42), with a counter electrode (40,44) between them. By controlling the currents to the two ion exchange electrodes (38,42) independently, the pH of the treated liquid can be controlled at a desired value.
