Wastewater treatment


At the wastewater treatment plant, reliability is paramount. Grundfos ensures low lifecycle costs and the hydraulic stability necessary for effective mechanical, biological and chemical treatment and the cost efficiency benefits that follow the optimising of treatment processes at the wastewater treatment plant.

Our contribution starts with the initial identification of needs and design expertise, including CFD flow simulations in the design and specification phase. Our pumping, mixing, dosing and aeration systems are optimised for each other, and we offer pre-engineered and optimised modules for treatment processes.

Grundfos pumping systems are available in a range of material variants that are designed for aggressive media and corrosive environments. Control and monitoring systems increase the potential for improving efficiency and reliability.

Fully automated, easy to use disinfection systems using chlorine compounds and complete dosing pump systems are available for the chemical treatment of large or small volumes of wastewater based on different technologies. 

The Grundfos Product Center helps you select the pump that best matches the wastewater treatment application.
