Reliable and energy-efficient wastewater transport
Dependable, energy-efficient solutions for your wastewater pumping stations and networks are essential for wastewater collection and transport. Grundfos offers market-leading highest-efficiency sewer pumps that include innovative and patented technologies such as the S-tube impeller and SmartTrim impeller adjustment.
We also supply prefabricated pumping stations complete with pumps, controls, valves and pipes, and sewage lift systems with sewage macerator pumps. When refurbishing existing pumping stations, we ensure a complete solution with easy installation and low downtime during the installation process. Grundfos offers consultancy and uses Computational Fluid Dynamics modelling to optimise flow patterns at the pumping station and retention tank. Our pressurised sewer network modelling tool with system simulation software also helps optimise the design.
Innovative hydraulics deliver reliable operation at lower total cost, meeting the challenges of urban wastewater
To meet the increasing complexity of urban wastewater, Grundfos has developed the Open S-tube® semi-open impeller, which provides high efficiency over a wide operating range.
When Danish utility company Mariagerfjord Vand A/S experienced hydrogen sulphide issues in a challenging pumping main, Grundfos Hydrogen Sulphide Solution quickly solved the problems. All odour issues have vanished and chemical expenses cut by 70% in the affected area.
Solving H2S issues based on actual operating conditions
Hydrogen sulphide formation in sewers is a complex process that depends on many factors, including temperature, the composition of the wastewater, retention time in the pipes, and when and for how long the manhole pump is running. An ideal solution to hydrogen sulphide problems must take all of these factors into account. It must be based on actual operational conditions in order to deal with this unpredictability. This is precisely the approach that has led to the Grundfos Hydrogen Sulphide Solution.
A drive can help lower energy consumption at wastewater pumping stations. But a drive on its own is not enough. You also need an intelligent wastewater pump controller such as Grundfos Dedicated Controls – a complete wastewater control and monitoring solution developed specifically for network pumping stations. Watch our chief engineer explain how it works.
