Applications
- Wastewater treatment — Treating wastewater is about maintaining optimal and effective processes at mechanical, biological and chemical treatment stages. A full-line supplier, Grundfos ensures that hydraulic stability is maintained and capacity not exceeded for all processes.
category
- AgitatorsAgitators, such as small-scale submersible mixers and large-scale flowmakers, are designed for prefabricated pumping stations and large tanks respectively. They ensure that particles remain evenly distributed in wastewater and sludge, preventing sedimentation and supporting treatment processes.
- Submersible wastewater pumpsGrundfos submersible wastewater pumps are designed as sealed units combining a pump and integrated motor that can operate below the surface of wastewater. Submersible wastewater pumps are perfect in permanent installations for efficient removal of wastewater from a property whether from washing machines, sinks and showers or drainage from the garden.
