Abstract

A water treatment apparatus is provided. In the water treatment apparatus, a filter unit includes a first electrochemical filter and a second electrochemical filter for filtering raw water. A control unit drives the first electrochemical filter and the second electrochemical filter. The first electrochemical filter and the second electrochemical filter are installed in parallel. The control unit controls the second electrochemical filter to perform a water purifying operation when the first electrochemical filter needs to be recycled.
