Tertiary treatment


Grundfos supplies pumps for filtering and disinfection solutions that ensure the treated wastewater is safe for discharge.

Centrifugal pump systems are available in a range of flow capacities and for dry or submerged installation ensure the correct feeding of sand filters. Hydro booster multistage boosting systems ensure easy management of pressure zones.

SMART Digital (DDA, DDC and DDE) diaphragm dosing pumps offer modularity, simplicity and flow intelligence and contribute to keeping life cycle costs low. In addition, Grundfos supplies motor-driven (DMX) diaphragm dosing pumps, oscillating positive displacement pumps (DMH), precision dosing (DDI) pumps, and large-volume (DME) dosing pumps for primary treatment activities.

Grundfos supplies fully automated, easy to use disinfection systems using chlorine compounds. The range includes full-vacuum chlorine gas (Cl2) dosing systems (Vaccuperm), sodium hypochlorite (NaOCl) electro-chlorination systems (Selcoperm), and chlorine dioxide (ClO2) preparation and dosing systems (Oxiperm). Accessories for measurement and control and photometric water analysis ensure complete control of dosing and disinfection processes.
