Abstract
A method is described for treating activated carbon configured to be included in a carbon block of a filter for a water purifier. The method includes: inserting the activated carbon into a chamber; injecting ozone generated from an ozone generator into the chamber, and applying pressure to the chamber; and modifying a surface of the activated carbon inserted into the chamber based on applying the pressure to the chamber that holds the ozone and the activated carbon.
