PURPOSE:To easily and efficiently separate concrete components from a suspension contg. high-mol.wt. substances as solutes by filtering the suspension while forming a flow of the suspension parallel to the tubular filter surface. CONSTITUTION:A columnar body 2 is provided in a porous tubular body 1 while keeping a constant clearance with the main tube body, a part of the suspension 3 is filtered to the outside of the tubular body 1 as a filtrate 4 while the suspension flows through the clearance between the tubular body 3 and the columnar body 2, and the suspension flows out as a concentrate 5 from the opposite side. Meanwhile, the outside of the porous tubular body can be used as a filter surface. The thickness of the clearance used as the passage is preferably controlled to 0.1-10mm. Consequently, concrete components can be easily and efficiently separated from the suspension contg. high-mol.wt. substances as solutes. The separator is disassembled after use, various chemicals are added to the clogged tubular body which is then heated, hence the tubular body is regenerated, and then the separator is assembled and can be reutilized.
