PROBLEM TO BE SOLVED: To prevent scale deposition and to remove a deposited scale by treating silica (SiO) in water used in a geothermal binary power generation system or a boiler system by an ozone-accelerated oxidation method.SOLUTION: A scale deposition prevention device 3 for removing SiOcontained in water supplied to a geothermal binary power generation system 100 or a boiler system 200 press-shears ozone gas and circulates and supplies the ozone gas to well water, causes the SiOcontained in the well water to be a silicate tetrahedron (SiO) having a negative surface potential to be connected to a cation.SELECTED DRAWING: Figure 2 【課題】地熱バイナリ発電システム又はボイラシステムに用いられる水中のシリカ（ＳｉＯ２）をオゾン促進酸化法により処理して、スケールの付着を防止及び付着したスケールを除去する。【解決手段】地熱バイナリ発電システム１００又はボイラシステム２００に供給される水に含まれるＳｉＯ２を除去するスケール付着防止装置３であって、井水にオゾンガスを加圧せん断して循環供給し、前記井水に含まれるＳｉＯ２を負表面電位を有するシリケート４面体（ＳｉＯ４）にしてカチオンと結合させることを特徴とする。【選択図】図２
