Hyperbolic Mixer

The DBS Hyperbolic Mixer is an advanced mixing solution for flocculation, suspension, homogenisation, and subsurface aeration in water and wastewater treatment processes. Its innovative rotor design ensures efficient mixing by operating at the bottom of the basin, where it draws water downward and discharges it horizontally. This induced flow circulates the water from bottom to top, maintaining all solids and/or chemicals in suspension for optimal process performance.

Key Features

1. Superior Energy Efficiency
Energy efficiency is a critical factor in modern water treatment operations. The DBS Hyperbolic Mixer is engineered to minimise energy consumption while maximising water movement. Its backwards-curved pump blades are specifically designed to move large volumes of water with minimal power input. Additionally, the high-efficiency speed reducer minimises power losses, resulting in optimum conversion of power input into water mixing energy.

2. Exceptional Durability and Reliability
The DBS Hyperbolic Mixer is built for longevity and high performance. The speed reducer is selected with a service factor that exceeds 100,000 hours of calculated life, ensuring long-term reliability. Heavy-duty output bearings provide robust support against all loads imposed by the rotor, eliminating the need for a lower guide bearing. The oversized drive shaft and sturdy mounting base minimise lateral rotor deflection and vibrations, ensuring stable and consistent operation.

3. High-Quality Materials for Corrosion Resistance
All wetted parts are manufactured from AISI 304 or AISI 316 stainless steel to provide excellent corrosion resistance in demanding environments. For applications involving highly saline or aggressive wastewaters, special coatings and materials are available to further enhance durability and performance. These include Super Duplex stainless steel, FRP, Carbon Fiber, Aluminium and Nickel/Monel.

4. Customisation Options
The DBS Hyperbolic Mixer is available in standard configurations ranging from 1 HP (0.75 kW) to 30 HP (22 kW). For projects with unique requirements, custom designs can be provided to ensure the mixer meets specific process needs.

Applications

The DBS Hyperbolic Mixer is widely used in water and wastewater treatment applications, where it delivers reliable and efficient mixing for various processes, including:

• Flocculation: Promotes the formation of flocs for improved sedimentation and filtration
• Suspension: Maintains solids in suspension to prevent settling and clogging
• Homogenisation: Ensures uniform distribution of chemicals, solids, or temperature
• Subsurface Aeration: Provides mixing that improves oxygen transfer in biological treatment processes.

Using a customer’s tank design details, Computational Fluid Dynamics (CFD) analysis can be used to simulate and demonstrate the mixing performance of the DBS Hyperbolic Mixer.

The DBS Hyperbolic Mixer is the ideal choice for facilities looking to enhance efficiency, reduce energy consumption, and ensure reliable operation in demanding environments. With its proven performance and advanced design, it meets the needs of modern water and wastewater treatment while supporting sustainable operations.
