Sludge dewatering and sludge drying
During preliminary sedimentation and final sedimentation in waste water treatment plants, the resulting concentrated sludge is either dewatered directly or fed via the anaerobic fermentation stage to sludge dewatering units. This conveying task is performed by the suction pumps of our KB and KL series.
In the dewatering units the sludge is dewatered with the help of decanting centrifuges, traveling screen presses, rotary filter presses or chamber filter presses and then pumped with a dry substance content (DS) of 20–45% for further treatment into containers, sludge tanks or directly to the sludge drying station. The pumping characteristics of the dewatered sludge varies in this case according to the DS content, composition and chemical conditioning. Accordingly varied are the pumping requirements which we meet with the specially developed jaw and silo pumps of our KL-R, KL-RÜ, KL-RS and KL-RQ series.
