Carrousel

The Carrousel: A Sustainable Solution for Wastewater Treatment

The term "Carrousel" in the context of environmental and water treatment refers to a specific type of biological oxidation/wastewater treatment system developed by DHV Water BV and licensed to Baker Process. This innovative technology offers a sustainable and efficient solution for treating a wide range of wastewater, particularly those containing high levels of organic matter.

What is the Carrousel System?

The Carrousel system is a biological wastewater treatment process that utilizes a series of rotating biological contactors (RBCs). These RBCs consist of large, rotating drums covered in plastic media that provide a large surface area for the growth of aerobic bacteria.

How it Works:

1. Wastewater Inlet: Wastewater enters the system and is pre-treated to remove large solids and grit.
2. Biological Oxidation: The pre-treated wastewater then flows through the RBCs. As the drums rotate, the media is constantly exposed to the wastewater, providing a continuous supply of oxygen for the aerobic bacteria. These bacteria break down the organic matter in the wastewater, converting it into harmless byproducts.
3. Clarification and Discharge: The treated wastewater flows through a clarifier, where any remaining solids are settled out. The final effluent is then discharged to a receiving water body or further treated for reuse.

Key Advantages of the Carrousel System:

• High Efficiency: The Carrousel system is highly efficient in removing organic matter and pollutants, even from wastewater with high organic loads.
• Low Energy Consumption: The rotating drums utilize low-energy motors, leading to significant energy savings compared to other treatment processes.
• Compact Design: The Carrousel system has a compact footprint, making it suitable for both large-scale industrial and smaller municipal applications.
• Modular Design: The system can be modularly expanded to accommodate increasing wastewater flows.
• Low Maintenance: The Carrousel system requires minimal maintenance, reducing operational costs.
• Stable Performance: The system is designed to operate consistently, even during fluctuations in wastewater flow and composition.

Applications of the Carrousel System:

The Carrousel system is widely used in a variety of wastewater treatment applications, including:

• Municipal wastewater treatment
• Industrial wastewater treatment (e.g., food processing, paper mills, breweries)
• Agricultural wastewater treatment
• Treatment of stormwater runoff

Conclusion:

The Carrousel system represents a sustainable and efficient solution for treating wastewater. Its high efficiency, low energy consumption, compact design, and stable performance make it a valuable tool for protecting the environment and conserving water resources. As the demand for sustainable wastewater treatment solutions continues to grow, the Carrousel system is likely to play an increasingly important role in ensuring a clean and healthy water environment.
