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.

Abstract: A filter for a water treatment apparatus includes a filter housing that defines an inlet of the filter and an outlet of the filter, and a filter module disposed inside the filter housing and configured to purify water received through the inlet and supply purified water to the outlet. The filter module includes a carbon block that has a hollow tube-shape and that comprises a mixture of activated carbon and a binder, and a non-woven fabric that surrounds an outer circumferential surface of the carbon block, the non-woven fabric comprising an electrostatic attraction material. The filter module is configured to receive water through the inlet, transmit the water through the non-woven fabric and the carbon block in sequence to thereby purify the water, and then discharge the purified water to the outlet of the filter.
