Abstract

A water treatment apparatus includes: a first granular electrode member and a second granular electrode member stored in a water treatment unit and provided so as to be separated from each other; a power supply unit which applies voltage between the first granular electrode member and the second granular electrode member so that ions contained in treatment target water supplied from one side of the water treatment unit are adsorbed to the first granular electrode member and the second granular electrode member; and a washing water supply pump which causes washing water to flow from the other side of the water treatment unit to the one side of the water treatment unit, thereby washing the first granular electrode member and the second granular electrode member, wherein the first granular electrode member and the second granular electrode member each include a plurality of flowable granular electrode members.
