Planning guideSolids separation systemsRequirementThe amount of solids in domestic sewage is continuously increasingdue to current water savings. This means that the pumps in pumpingstations need even larger free ball passages, which also means an increasein pump power consumption.FunctionWith the solids separation system, the inflowing sewage flows intothe distribution tank and from there into the open solids separationtank. The solids are kept back here. Only prepurified sewage is nowable to pass through the pump into the large, combined collectionreservoir.While the collection reservoir is filled, the water level in the solidsseparation tank rises. The shut-off ball automatically closes the inlet.Now, pumping starts when the correct level has been reached. Thepump pumps in the reverse direction. The sewage flows through thesolids separation reservoir and thus conveys the “filtered-out“ solidsinto the outgoing pressure pipe.Then, the entire solids separation system is flushed and cleaned.Pumping is stopped again, when the correct level has been reached.The shut-off ball drops, leaving the path free for a new filling sequence.During this pumping sequence, the sewage is pumped intothe other solids separation reservoir.Advantages of the solids separation system• Uses pumps with free ball passage < 80 mm, thus reducing fuel requirementsand operating costs while increasing efficiency• Hygienic conditions for maintenance and assembly work• Pump room is clean, dry, and odourless• Less wear, since the solids are not pumped by the hydraulic unit• Submersible sewage pump with adjusted impeller and protectionclass IP 68 (submersible)• No corrosion problems, no effect from the formation of hydrogensulphide871264531 = inlet pipe, 2 = manifold, 3 = solids collection reservoir , 4 = solids separation flap, 5 = collection reservoir with filtered sewage, 6 = shut-off ball, 7 = dischargepipeline, 8 = ventilation and exhaust18 Wilo Water Management catalogue – 50 Hz – Drainage and Sewage – Waste water collection and transport – Edition 2012/2013 – Subject to change without prior notice
