The wastewater entering at a wastewater treatment plant’s inlet pumping station contains all substances that have entered the sewer system. This is not only what we flush down the toilet, but also industrial effluents, wastewater from hotels, hospitals and restaurants, and substances drawn directly into the sewer system through manholes.
Grundfos has the pumps to cope with these heavy demands. The Grundfos ranges of SE/SL, S, and KWM pumps are specifically designed for durable use and heavy sewage flows and can be installed dry or submerged. If the design of the pump sump does not prevent sedimentation, the Grundfos range of robust AMD mixers ensure full mixing and thereby ensure trouble-free operation and prevent odours.
The inlet pumping station involves great fluctuations in demand for performance. With multiple inlet pumps installed, adding external variable speed drives (Grundfos CUE) will equalize the hydraulic load to the wastewater treatment plant. Computational Fluid Dynamics (CFD) simulations at the design phase helps ensure the optimum delivery of wastewater through the inlet pumping station for mechanical treatment by visualising hydraulic conditions at the pumping station.
Control and monitoring systems increase the potential for improving both efficiency and reliability. In addition to variable speed drives, Grundfos supplies motor protection (MP204) to monitor motor conditions, ensuring optimal operation.
Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts.
