Primary treatment activities help create optimal conditions for settling with flow conditions and water velocities designed to favour sedimentation. Grundfos supplies durable pump systems for steady outflow of settled material for the screening station, sand, grit and grease removal, and the equalisation tank.
Grundfos offers consultancy and uses Computational Fluid Dynamics modelling to optimise flow patterns at the equalisation tank. Find out more about CFD analysis and equalisation tank design.
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.
Grundfos SE/SL, S and KWM wastewater pumps are designed for durable use with heavy, fluctuating sewage flows. For screening stations, Hydro booster multistage boosting systems ensure easy management of pressure zones. Diffuser systems from Grundfos offer fine or coarse bubble diffusers for large air flows for sand, grit and grease removal separation processes.
