ELECTRODEIONIZATION WATER PURIFIER SYSTEM OPERATED BY INTERMITTENT REGENERATION PROCESS CAPABLE OF INTERMITTENTLY REGENERATING ION EXCHANGER AND METHOD FOR CONTROLLING INTERMITTENT REGENERATION THEREOF

摘要

PURPOSE: To provide an electrodeionization water purifier system operated by an intermittent regeneration process, which is able to simplify constitution of the system by allowing an ion exchanger to be intermittently regenerated by a measurement means, and a method for controlling the intermittent regeneration thereof. CONSTITUTION: Between a pre-treatment carbon filter (12) and a post-treatment carbon filter (14), an electrodeionization module (13) is installed. A measurement means (200) is equipped between the electrodeionization module and the post-treatment carbon filter and determines a periodic regeneration time of an ion exchanger based on conditions of accumulated value that is measured by the measurement means to allow the ion exchanger to be intermittently regenerated.
