Aquaspir: Revolutionizing Dewatering with Shaftless Screw Technology

1.1 Introduction

Dewatering, the process of removing water from solid-liquid mixtures, is a crucial step in various industries, including wastewater treatment, food processing, mining, and pulp & paper. Traditional methods, often involving centrifugal or filter presses, can be energy-intensive, prone to maintenance issues, and may not achieve desired solids content.

Aquaspir, developed by Andritz-Ruthner, Inc., offers a revolutionary approach to dewatering using a unique shaftless screw design. This innovative technology addresses the limitations of conventional methods, providing superior performance, efficiency, and reliability.

1.2 The Aquaspir Principle

Aquaspir utilizes a centrally supported, rotating helical screw that conveys and dewaters material through a series of pressure zones. The screw's rotation creates centrifugal forces, pushing the liquid towards the outer periphery while simultaneously pressing the solids against the screw's surface.

1.3 Key Differences from Conventional Screw Presses:

• Shaftless design: Eliminates the need for traditional shafts, bearings, and seals, leading to increased efficiency, reliability, and simplified maintenance.
• Centrally supported screw: Enhances stability and reduces vibration, ensuring smooth operation.
• Pressure zones: The screw's design incorporates specific pressure zones, optimizing the dewatering process for different materials and desired solids content.

1.4 Advantages of Aquaspir's Shaftless Screw Technology:

• Reduced friction and energy consumption: The absence of shafts and bearings minimizes friction, leading to higher throughput and reduced energy consumption compared to traditional screw presses.
• Enhanced reliability: The shaftless design eliminates the potential for shaft breakage, bearing failure, and seal leaks, extending equipment lifespan and minimizing downtime.
• Simplified maintenance: The absence of complex mechanical components simplifies maintenance procedures and reduces associated costs.
• Improved hygiene: The shaftless design eliminates potential contamination points, making it ideal for food processing, pharmaceutical, and other sensitive applications.
• Adaptability: Aquaspir can be customized to handle a wide range of materials, from thin slurries to thick sludge, by adjusting screw geometry and pressure zones.

1.5 Conclusion

Aquaspir's innovative shaftless screw technology provides a superior dewatering solution compared to conventional methods. Its enhanced efficiency, reliability, and simplified maintenance make it a compelling choice for a wide range of industrial and environmental applications.
