1a into the container 11, and since the lower frame 21 of the uppermost filter B20 and the inner wall of the container 111 are sealed with the O ring 29, the water that has passed from the outer filter 24 to the filter 1125 and the inner filter 23, The hole 21a in the center of the lower frame 21 reaches the second stage filter vessel 20, and the inside of the upper frame 22 of the second stage filter vessel 20 and the container 11! Similarly, the water passes through the outer filter 24, the filter 1125, and the inner filter 23, and then similarly passes through the lowermost funnel 20 and flows out from the outlet 11b of the container 11 to the pipe 15.

多孔質であるため、水中に溶存したにおいの成分が吸着
されて、臭気のある水を無臭にする。Impurities such as dirt in the water are removed by an outer filter 24 and an inner filter 23. Since the filter medium of the filter 125 is porous, odor components dissolved in the water are adsorbed, making odorless water odorless.
且つ、ろ材中のＣａＯが水に溶けて
ＣへＱ ＋１−（２０→Ｃユ（ＯＨ）２Ｃａ（Ｏ）４）

Ｃａ”十〇Ｈ″″のように水酸基ＯＨを生じて、水酸基
濃度を＾め、酸性の水を中性あるいはアルカリ性にする
。Moreover, CaO in the filter medium dissolves in water and converts to C. Q +1-(20→Cyu(OH)2Ca(O)4)
2→Ca(O)-1f+0H-Ca(Of-1)"-+
Produces hydroxyl group OH as in Ca"10H", lowers the hydroxyl group concentration, and makes acidic water neutral or alkaline.
なお、ＣａＯ，ＳｉＯ２の含有量は、ＣａＯが１０〜４
０％、好ましくは２５％、Ｓｉｎ、の含有量は６５〜３
５％、好ましくは５０％が適当である。Note that the content of CaO and SiO2 is 10 to 4.
0%, preferably 25%, Sin content is 65-3
5%, preferably 50% is suitable.
ＣａＯの含有量が４０％を超えると、水への溶解反応が
高くなりすぎ、ろ材としての消耗が大きくなりすぎる。When the content of CaO exceeds 40%, the dissolution reaction in water becomes too high, resulting in excessive consumption as a filter medium.
また１０％より少ないと、ｐＨ値が高くならない。Moreover, if it is less than 10%, the pH value will not become high.
また、Ｓｉへの含有量が３５％より少ないと、多孔質に
ならず、ＣａＯが多くなりすぎて溶けやすくなり、ろ材
としの消耗が大きくなりすぎる。On the other hand, if the content of Si is less than 35%, it will not become porous, and the amount of CaO will be too large, making it easy to dissolve, resulting in excessive wear as a filter medium.

の陽極電極４３内を通過させる。The water that has passed through the device 10 in this way is
Not only are impurities such as dust removed, but components such as odors are also removed, and if acidic, it is modified to be neutral or alkaline, but calcium components are dissolved. For this reason, when the water that has passed through the filter device 10 is heated and used as hot water, the hardness of the water increases, and calcium components precipitate as CαCO3 and adhere to the pipes of the downstream heat exchanger, etc., clogging the passages. or cause a decrease in thermal efficiency. In order to prevent this, the water that has passed through the filter M10 is passed through the pipe 11b and the pipe 15, and then through the inner cylindrical anode electrode 43 of the electrode treatment device [40].
電極処理装置４０内では、ここを通る水が電解質である

イプ内へのカルシウム成分の析出が著しく低減される。In the electrode treatment device 40, since the water passing through it is an electrolyte, a voltage of about 0.7V is generated between the cylindrical anode electrode 43 and the rod-shaped anode electrode 44, and a current flows through the flowing water, causing polymolecules ( This gives kinetic energy to the clustered water molecules, increasing the activity of the water, and fragmenting the dissolved solids of calcium present in the water into fine single crystals. Therefore, the dissolved solids become suspended substances in the water, and therefore flow without adhering to the latter part of the vibrator. Therefore, precipitation of calcium components into the pipe is significantly reduced.

This makes the device smaller and cheaper, and also reduces the amount of CaO in the filter medium.
is dissolved in water and water i! Since it is possible to modify the quality of highly acidic water to neutral or alkaline by generating groups, it is possible to prevent corrosion inside the piping and further prevent the precipitation of calcium components.
