Summary:PURPOSE:To remove solids contg. sludge efficiently from aq. waste sludge by providing a sludge supply tank for cyclones below a vibrating sieving machine, and connecting the undersize sludge water on the bed to sludge feed tanks respectively through a distributor and a distribution tank. CONSTITUTION:The undersize sludge water produced by sieving the underflow of a primary cyclone 2 on the bed of a sieving machine 1 is connected to both of sludge feed tanks 4a, 4b for primary and secondary cyclones via a distributor 8. The overflow of the cyclone 2 is connected to both of the tanks 4a, 4b via a distribution tank 6 which distributes the same to the liquid volume to be retained in the circulation system of both cyclones 2, 3 and the liquid volume to be flowed to the outside of the circulation system. This is convenient for controlling the concn. of the feed liquid of the secondary cyclone 3 while maintainig the balance of the liquid volume over the entire part.
