摘要： In a preferred embodiment, a rotary filter or dewatering device having a conical shape in which the precoat is on the inside of the conical filter, and in which pressure within the cone and/or vacuum on the outside surface of the conical filter creates a differential pressure causing a feed within the conical filter to be filtered through the filter, and the filtrate to be collected outside of the conical filter. A revolving knife having a spiral contour and being concentric to the conical filter, fractionally advances axially into the conical filter at a predetermined rate to cut away a surface layer of the precoat, the spiral contour serving also to force the sludge of filtered solids to an outlet from said conical filter. The invention also includes the process of precoating, filtering under a differential pressure, and cutting away the precoat from within the conical filter.
