る。In the filtration device, when the liquid is formed from the formation tube 14, the formed liquid is passed from the lower chamber 4 to the cylindrical filter ``''''6.
The liquid passes through the upper chamber 3, is filtered, moves to the upper chamber 3, and is discharged from the upper chamber 3 through the liquid outlet pipe 21, but is not washed, and paper, fiber materials, or any of these materials are left in the water in the filter medium tank 20. After melting and thoroughly mixing the filter medium made of the mixed material, the valves 13, 24, 25.
27 is closed, the other valves 23, 26, and 28 are opened, and the pump 15 sends the water mixed with the filter medium in the filter medium tank 20 without sifting, and the water enters the lower chamber 4 from the large growth pipe 14 and becomes cylindrical. The liquid passes through the filter 6 and is filtered, moves to the upper chamber 3, and circulates from the drain pipe 21 to the branch pipe 22 to the filter medium tank 20. At this time, the filter medium mixed into the water is distributed almost uniformly on the wall surface of the cylindrical filter 6. Follow the lunar calendar. After that, this time valves 13, 24, 26
．． 28 is closed, other valves 23, 25, and 27 are opened, and the liquid to be filtered, for example, the polishing liquid 17 after polishing, is sent by the pump 15, and the liquid 17 flows from the large tube 14 into the lower chamber 4. The liquid passes through the inlet cylindrical filter 6 and is filtered, and the filtered liquid moves to the upper chamber 3 and is circulated to the liquid tank 16 through the outlet liquid pipe 21. At this time, since the wall surface of the cylindrical filter 6 is covered with the adhering filter medium, the noble metals (particularly in the form of powder or granules) mixed in the processed polishing liquid are filtered and adhered to the filter medium.
