Abstract
A deionization filter, a water treatment apparatus including the deionization filter, and a method for regenerating the deionization filter are provided. The method includes a raw water total dissolved solids (TDS) measuring process of generating a raw water TDS value by measuring a TDS value of solid matter contained in raw water; an accumulated solids amount calculating process of generating an accumulated solids amount by adding up the amount of solid matter eliminated by the deionization filter removing the solid matter contained in the raw water; and a regenerating process of performing a regeneration operation on the deionization filter when the accumulated solids amount is equal to or greater than a predetermined solids amount limit.
