    Abstract: A filter for a water treatment apparatus includes: a current collector; activated carbon electrodes including an active carbon coating layer that is disposed on one or both sides of the current collector and that has an uneven pattern; spacers disposed between the activated carbon electrodes; electrode plates connected to side ends of the activated carbon electrodes; and a power supply configured to supply currents through the electrode plates to the activated carbon electrodes such that neighboring activated carbon electrodes alternatively form an anode and a cathode. The filter can decrease water hardness and has a high ion removing performance because the uneven pattern increases the specific surface area and water permeability, and an ion exchange membrane is not used and the current collector has a minimized volume, leading to the minimal thickness of the electrode.

    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.

    Abstract: A filter module for a water treatment apparatus, and a water treatment apparatus comprising the filter module includes: stacked active carbon fiber layers made of active carbon fiber; spacers inserted between the active carbon fiber layers; a pair of current collectors connected to an end of the stacked active carbon fiber layers; and an active carbon fiber filter included stacked one or more active carbon fiber filter units, each active carbon fiber filter unit including a power supply for supplying current to the active carbon fiber layers via the current collectors so that neighboring active carbon fiber layers form cathodes and anodes in alternation. The filter module can lower the hardness of the water while increasing ion removal capability by increasing the specific surface area and water permeability, and can minimize the thickness of the electrodes by eliminating ion exchange membranes and minimizing the volume of current collectors.
