WATER TREATMENT APPARATUS

To provide a water treatment apparatus that can monitor regenerated salt at low cost.SOLUTION: A water treatment device 10: comprising a filtration tank 22 accommodating filter material 32; a regeneration tank 23 that is connected to the filter tank 22, accommodates regeneration salt 46 that generates salt water S for regenerating the filter material 32, and stores the salt water S generated from treat water L2 and the regeneration salt 46; a float switch 45 that is installed inside the regeneration tank 23 and is provided with a float 45a that floats at a concentration of the salt water S at which the filter material 32 can be regenerated, and sinks at a concentration of the salt water S at which the risk of the regeneration of the filter material 32 can be determined, in regeneration processing of introducing the salt water S in the regeneration tank 23 into the filter material 32, and a detection unit 45b that outputs a signal indicating whether the float 45a is floating or sinking; report means 102c for reporting information to the outside; and a control unit 102c that controls the reporting means 102c to report the risk on regeneration at the time when it is determined that the float 45a has settled in the salt water S in the regeneration tank 23.SELECTED DRAWING: Figure 3 【課題】安価に再生塩の監視ができる水処理装置を提供すること。【解決手段】水処理装置１０は、濾過材３２を収容する濾過槽２２と、濾過材３２を再生する塩水Ｓを生成する再生塩４６を収容するとともに、処理水Ｌ２及び再生塩４６で生成される塩水Ｓを貯留する、濾過槽２２に接続された再生タンク２３と、再生タンク２３内に設けられ、再生タンク２３内の塩水Ｓを濾過材３２に導入する再生処理において、濾過材３２を再生できる塩水Ｓの濃度で浮上し、濾過材３２の再生リスクを判定できる塩水Ｓの濃度で沈降する浮き子４５ａ及び浮き子４５ａの浮上又は沈降の信号を出力する検出部４５ｂを有するフロートスイッチ４５と、外部に情報を報知する報知手段１０２ｃと、再生タンク２３内の塩水Ｓに浮き子４５ａが沈降していることを判定し、報知手段１０２ｃを制御し、再生リスクを報知する制御部１０２ｃと、を備える。【選択図】 図３
