A system of continuously and efficiently separating liquid from sludge is disclosed which includes two parts, the mixer conditioner and the rotary drain. The two parts are virtually always used together. The mixer conditioner may include an adjacent vertical receiver which may serve to extend residence time. The receiver, if used, is connected at the bottom to the tangential inlet line to the mixer conditioner. This inlet line provides the means for circulation therethrough the watery sludge to which has been added a flocculant in a gentle manner so as to cause mixing while not causing shearing. A slow moving horizontal impeller operates to maintain the spiraling motion initiated at the tangential inlet. The outlet, also tangential, delivers to the rotary drain. The rotary drain is a compartmentalized cage that is decreasingly baffled from compartment to compartment. Each compartment is an individual cage with its own individual wire mesh, providing therein the means to easily vary the mesh or openness from cage to cage. The baffles are provided with adjustable ports to modify almost infinitely the number of changes that are possible internally and mechanically to maximize output quality independently of flow.
