ABSTRACT:
An apparatus for filtering waste water containing radioactive solid particles or produced in a nuclear reactor power plant and wherein the water is filtered with a plurality of U-shaped hollow fibers each having a sponge like mesh structure containing numerous pores for trapping radioactive substances, the hollow fibers being made of flexible polyethylene and each pore having a diameter of about 0.1 micron. An air pipe is provided beneath the U-shaped hollow fibers for bubbling air into water to be filtered surrounding the fibers, thereby removing solid particles trapped in the pores.
