Abstract

PURPOSE:To improve the separation efficiency by rotatably mounting the revolv ing tube shaft of a filter drum in a vacuum vessel and furnishing an extraction pipe and a supply pipe in the revolving tube shaft. CONSTITUTION:The inside of the vacuum vessel 1 is evacuated by driving a vacuum pump 3, and the inside of the filter drum 6 is pressurized by driving a liquid supply pump and an air compressor 17. By driving a drive motor 22, the revolving shaft 22a drives a sprocket 21 through a transmission chain 23, and the filter drum 6 is slowly revolved. The liquid to be treated supplied by the liquid supply pump 16 is separated into a concentrated liquid and a separat ed liquid by a filter 6a while being moved in pendulum motion by the filter drum 6. By this method, the pressure-resistivity and the corrosion-resistivity are improved.
