wastewater sewage and sludge Pump
Pumps for Sewage, Sludge, Slurry in Wastewater Treatment Plant
NETZSCH Pumps and Systems offers innovative pumping solutions to transfer dewatered sewage, sludge, slurry & standard pumps in wastewater treatment plants. NEMO® BF hopper-shaped pump with aBP-Module® prevents system downtime.
The dewatered sewage, sludge, and slurry pumps used in industrial wastewater treatment plants is particularly solid. Pumping the sludge & slurry poses challenges for wastewater treatment plant operators worldwide.
As a global expert in complex fluid management, NETZSCH Pumps & Systems provides customized different types of wastewater treatment pumps for your industrial wastewater treatment plants.
We will show you how wastewater treatment pumps to prevent a plant shutdown due to clogging or bridging by using a NEMO® BF hopper shaped pump with aBP-Module® specially developed for wastewater treatment plants.

How pumps are utilized in the dewatering of sewage sludge.
To be able to store and reuse the sludge from a wastewater treatment plant, later on, it has to be processed. At the wastewater treatment plant in Celle, the sludge is first dewatered in an angle press, and a flocculant is added.
The dry sludge is pumped from the wastewater treatment plant through a pressure pipe with 90-degree bends about 25 meters into a silo. It is then distributed from the silo to agricultural land. The sewage sludge later serves as fertilizer because of the nutrients it contains.
Pump difficulties are caused on by regularly solid sewage sludge.
Due to the high strength of the sewage sludge, there were frequent blockages and bridging in the wastewater treatment plant, resulting in operational downtimes. The downtime amounted to a total of three to four hours per week. The wastewater treatment plant needed a reliable pumping system to prevent plant shutdowns and the associated operational failures.
NEMO® BF hopper pump with aBP modules® conveys solid sewage sludge
NETZSCH developed the NEMO® BF hopper shaped pump with aBP-Module®, especially for highly viscous, stab-resistant and crumbly media. This consists of a top shaft with flat spoked wheels mounted on the inside.
The wheels sit deep in the shaft and close to the wall. If they rotate, this affects the material being conveyed, as if the entire sides of the shaft were moving. Thus, using the NEMO® BF pump to convey solid sewage sludge prevents clogging and bridging.
At the wastewater treatment plant in celle and many other operators, the pump system with the integrated bridge breaker has proven itself in continuous use. The robust hopper pump increases operational safety and prevents plant shutdowns even without tiresome inspection trips to the conveyor.
