1.What is a vertical hyperboloid agitator mixer?
A vertical hyperboloid agitator mixer is a submersible or dry-mounted mixing device with a hyperboloid (curved, hyperbolic surface) impeller mounted on a vertical shaft near the tank bottom. The impeller rotates at low speeds (typically 20-250 RPM) to create a bottom-up circulating flow, combining axial (vertical) and radial (horizontal) movements for thorough homogenization. This design, pioneered in the 1990s by INVENT, excels in suspending solids, preventing sedimentation, and mixing solids, liquids, and gases without high energy use.
2.How does a hyperboloid mixer work?
The hyperboloid impeller draws fluid downward and accelerates it radially outward along its curved surface, creating turbulent flow at the tank bottom. This flow reflects off the tank walls, forming a spiral circulation that rises upward and recirculates. The large impeller diameter (500-2800 mm) and low rotational speed minimize shear forces on sensitive particles (e.g., flocs in wastewater), while generating high turbulence to resuspend solids. Computational fluid dynamics (CFD) simulations confirm no dead zones, even in deep or irregularly shaped tanks.
3.What are the main applications?
These mixers are ideal for wastewater treatment processes like equalization tanks, anaerobic digesters, anoxic/oxic zones (AO/A2O), flocculation, nitrification/denitrification, and sludge homogenization. They're also used in industrial settings for chemical blending, food processing, and pulp/paper industries where low-shear mixing of viscous or solid-laden fluids is needed. They handle tank volumes from 1-22 m² per unit and depths up to very deep basins (e.g., HYPERDIVE® for >10m).
4.What are the key advantages over traditional mixers?
Energy Efficiency: Consumes as low as 2 W/m³ in activated sludge tanks, far below jet mixers or high-speed propellers, due to optimized flow patterns. Low Shear: Hyperboloid shape and slow speeds (e.g., <100 RPM) protect fragile flocs or emulsions, unlike high-shear agitators. No Dead Zones: Radial outflow covers the entire bottom, eliminating sedimentation in corners. Versatility: Works in round, square, or rectangular tanks; multiple units can be used for larger volumes. Durability: Corrosion-resistant materials (stainless steel or FRP) and low maintenance needs.
