Abstract: A system is provided with a solid-liquid separator which can transport sludge and other material for treatment without clogging and can efficiently separator liquid from such material for treatment. The system includes movable plates and fixed plates alternatingly disposed and two screws disposed in holes formed in the movable plates and fixed plates. The screws have blades that partially overlap. As the two screws rotate, the material for treatment is transported and the effluent is discharged through the gaps between the movable plates and fixed plates.

Abstract: A solid-liquid separator comprising a number of stationary rings arranged with spaces left therebetween, a number of floating rings each disposed movably in the spaces between the stationary rings and a screw conveyor provided in the inner space of the stationary and floating rings. The screw conveyor is driven in rotation to convey sludge water introduced into the space, and while being conveyed, only a water portion thereof is discharged to the exterior through the minute gaps between the floating and stationary rings. The motion of the floating ring prevents clogging of the solid portion in the minute gaps.
