Problems solved by technology
[0003] However, during the regeneration, since the deionization operation may be interrupted, the operation of generating purified water using the deionization filter may also be interrupted.
Furthermore, untreated water introduced at the time of regeneration operations may be discarded together with adsorbed ionic species in order to expel said ionic species, wherein a relatively large amount of water is wasted
[0004] Particularly, in the case of a region having untreated water containing a large amount of hard water components such as metal ions, etc., if the deionization filter works in the same manner as in the case of a general region, a large amount of ion Substances may not be removed from untreated water, and said regeneration operations may not be taking place at the desired moment

The present invention relates to a deionization filter, a water treatment apparatus comprising a deionization filter, and to a method for regenerating a deionization filter. The method for regenerating the deionization filter, according to one embodiment of the present invention, comprises: a feed water total dissolved solution (TDS) measurement step of generating a feed water TDS value by measuring a TDS value of a solid substance that is included in the feed water; an accumulated solid substance amount calculation step of adding the amount of the solid substance, which is removed by the deionization filter which removes the solid substance that is contained in the feed water, to generate an accumulated solid substance amount; and a regeneration step of performing a regeneration action for the deionization filter when the accumulated solid substance amount is at least a predetermined solid substance amount limit.
Description
technical field [0001] The present invention relates to a deionization filter, a water treatment device comprising the deionization filter and a method of regenerating the deionization filter, and, more particularly, to a deionization filter capable of being adsorbed to the deionization filter by calculation A deionization filter whose regeneration time is determined by the amount of solid matter, a water treatment device including the deionization filter, and a method for regenerating the deionization filter. Background technique [0002] Deionization filters remove ionic substances, etc. contained in untreated water, and generate pure water using electric attraction. The deionization filter can remove ionic species from untreated water using a variety of methods. However, the amount of ionic substances that can be adsorbed to the deionization filter may be limited, and after adsorbing and removing a preset amount or more of ionic substances, it is necessary to perform dei...
