ABSTRACT:
A pretreatment step for the defouling of the compartments used in electrodeionization apparatus in which a solution of sodium percarbonate is contacted with the compartments to break up agglomerations of organic contaminants and colloidal films as well as to kill bacteria resident within the system. After this pretreatment step any conventional cleaning may be performed to complete the cleaning cycle.
