PURPOSE:To treat high-density slurry and high-viscosity liquid by providing a number of separation means readially around the outer circumference of a hollow revolving cylinder to enlarge the surface area of separation means per unit area and controlling the thickness of gel layer and cake layer formed on the surface area of separation means. CONSTITUTION:Plate type separation means 2 of separating membrane and the like are provided radially to the direction crossing the axial direction of revolving cylinder 1 on the outer circumference of hollow revolving cylinder 1. Interconnecting holes to interconnect the penetrating liquid of separation means 2 with the inside of revolving cylinder 1 are provided nt he revolving cylinder 1. By accommodating the said device in the tank and rotating, liquid to be treated can be passed along the surface of separation mans 2 at a specified speed and the thicknesses of the gel layer and the cake layer are controlled with shearing force acting or the gel layer and the cake layer formed on the surface of separation means 2. The liquid peneotrated the separation means passes from the inside of separation means2 into the revolving cylinder 1 through the interconnecting holes to be extracted out of the device.
