impellers. Hydrofoil impeller is a low cost alternative to propellers. Vertical impeller flocculator has high energy efficiency (it means less power is required) and has low shear stress (lower variation in G). Also it can compact flocs well and has less settling problem at the bottom. Direction of water flow by impeller rotation must be down to prevent settling, and motor is on the top of the ta
