In some cases, a cylindrical trough is rotated manually or electrically, and scum is introduced into the trough together with water through an inlet formed by cutting a front surface of the trough. In addition, what is generally called a non-powered scum remover,
An overflow weir is attached to the front of a fixed rectangular trough, and the overflow weir is treated manually or by means of power transmitted mechanically by equipment linked to the movement of the flight plate, or treated water discharged from other equipment. It is widely known that the scum is pushed down by using the scum so as to flow into the inside of the trough and be eliminated.

Further, even in the case of using the treated water, the operation state becomes unstable due to clogging of the pipe or fluctuation in the water pressure of the treated water, and at present, there are many restrictions on the operation management in the actual operation. In addition, even in the case of a non-powered type, there are many cases in which an electric valve or the like is actually used, and it is necessary to use general power supply as power.
