The Aero-Accelator: A Compact Solution for Wastewater Treatment

The Aero-Accelator, a circular, packaged activated sludge treatment plant developed by Infilco Degremont, Inc., represents a significant advancement in wastewater management. This innovative technology offers a compact and efficient solution for treating municipal and industrial wastewater, particularly in situations where space is limited or traditional treatment methods are impractical.

The Aero-Accelator's Unique Design:

The heart of the Aero-Accelator lies in its unique circular design. This configuration allows for a continuous flow of wastewater through the system, ensuring consistent treatment. The circular tank is divided into distinct zones:

  • Aeration Zone: This zone houses a series of submerged diffusers that introduce air into the wastewater, promoting the growth of beneficial bacteria. These bacteria break down organic matter and pollutants, effectively purifying the wastewater.
  • Clarification Zone: This zone allows the treated wastewater to settle, separating the solid biomass from the clear effluent.
  • Solids Return Zone: A sludge return system continuously recirculates a portion of the settled solids back to the aeration zone, maintaining a healthy bacterial population for ongoing treatment.

Advantages of the Aero-Accelator:

  • Compact Design: The circular design allows for a much smaller footprint compared to traditional rectangular treatment plants, making it ideal for confined spaces.
  • High Efficiency: The continuous flow and robust aeration system ensure efficient removal of pollutants, leading to a high-quality effluent.
  • Low Maintenance: The system's automated operation and durable construction minimize the need for regular maintenance.
  • Modular Construction: Aero-Accelator plants can be easily scaled up or down to meet changing treatment requirements.
  • Environmental Benefits: By effectively removing pollutants from wastewater, the Aero-Accelator contributes to cleaner water sources and a healthier environment.

Applications of the Aero-Accelator:

The Aero-Accelator is suitable for a wide range of applications, including:

  • Municipal Wastewater Treatment: Treating wastewater from residential areas, commercial buildings, and public facilities.
  • Industrial Wastewater Treatment: Addressing specific pollutants from industrial processes, including food processing, manufacturing, and pharmaceuticals.
  • Small-Scale Treatment: Providing wastewater treatment solutions for remote locations, rural communities, and off-grid applications.

Conclusion:

The Aero-Accelator is a game-changer in the field of wastewater treatment. Its compact design, high efficiency, and low maintenance requirements make it a viable and practical solution for a diverse range of applications. As environmental regulations become more stringent and sustainable practices become paramount, the Aero-Accelator stands as a testament to innovation in wastewater management, paving the way for a cleaner and healthier future.
