Flocculation and aeration


Grundfos delivers the reliability required with complete dosing pump systems that ensure correct flocculation for the purification of drinking water, based on reliable, efficient and intelligent technologies.

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 also supplies PLC-controlled, fully automatic systems (Polydos) to handle preparation and the reliable dosing of organic coagulants or poly-electrolytes. Accessories for measurement and control and photometric water analysis ensure complete control of dosing and disinfection processes.

Grundfos SE/SL pumps are specifically designed for durable use and reliable flow management, and can be installed dry or submerged. Grundfos AMD/AMG mixers ensure even mixing in the tank.
