To provide a water treatment apparatus capable of suppressing increase in pressure and flow rate and providing a stable medicine supply.SOLUTION: A water treatment apparatus 1 includes a filter part 2 containing a filtering material inside, a raw water inflow pipe 10 for allowing raw water to flow into the filter part 2, a medicine supply unit 3 for adding a medicine in the path of the raw water inflow pipe 10, a purified water discharge pipe 20 for removing purified water after filtration from the filter part 2, and a detection unit 25 for detecting the water pressure or the amount of water in the raw water inflow pipe 10. The detection unit 25 controls the operation of an electric pump 4 which supplies water to the raw water inflow pipe 10 according to the water pressure or the amount of water in the raw water inflow pipe 10 to prevent an excessive amount of water from flowing into the medicine supply unit, so that a stable concentration of the chemical solution can be obtained.SELECTED DRAWING: Figure 1 【課題】圧力・流量上昇を抑制し、安定した薬剤供給を行う水処理装置を提供する。【解決手段】本発明に係る水処理装置１は、濾材を内包した濾過部２と、濾過部２に原水を流入させるための原水流入配管１０と、原水流入配管１０の経路内で薬剤を添加する薬剤供給部３と、濾過部２から濾過後の浄水を取り出すための浄水吐出配管２０と、原水流入配管１０内の水圧または水量を検知する検知部２５と、を有し、検知部２５は、薬剤供給部に過剰な水量が流入することを抑制するために、原水流入配管１０内の水圧または水量によって原水流入配管１０に水を供給する電動ポンプ４の動作を制御することで、安定した薬液濃度を得ることができる。【選択図】図１
