Versatility in Major Wastewater Treatment Processes

In the world of wastewater treatment, different processes have unique requirements. One common factor is the need for efficient and reliable aeration, and Inovair's high-speed, high-efficiency blowers excel in meeting these demands. Below, we explore how Inovair blowers perform in various major wastewater processes, supported by real-world case studies.

Sequencing Batch Reactors (SBR)

Sequencing Batch Reactors (SBR) combine the treatment step and the clarification step in the same tank. The blower is in a constant state of on/off, providing aeration during the active sludge phase and halting during clarification. Inovair’s use of oil film bearings ensures there is lubrication during the on/off cycle, providing durable, yet ultra efficient, air flow.

 

Case Study: New Madrid, MO

 

In New Madrid, Missouri, the local wastewater treatment facility implemented SBRs using Inovair blowers. The high-speed blowers demonstrated exceptional reliability and efficiency, handling the frequent start/stop demands without issue. This case study highlights the robustness and suitability of Inovair blowers for SBR processes, leading to significant energy savings and operational stability.

Membrane Bioreactors (MBR)

Membrane Bioreactors (MBR) involve high Mixed Liquor Suspended Solids (MLSS) concentrations, requiring aeration for biological treatment and membrane scouring. Inovair blowers provide the necessary air supply, ensuring efficient treatment and maintenance of membrane performance. The Inovair enhanced control system seamlessly integrates with the MBR OEM to guarantee optimal performance.

 

Case Study: Dunedin, FL

 
In Dunedin, Florida, an MBR system was enhanced by integrating Inovair blowers. The blowers efficiently supported both biological processes and membrane cleaning, accommodating the high MLSS levels and contributing to a smaller, more effective treatment footprint. This case exemplifies the adaptability of Inovair blowers in complex MBR environments.

Lagoons

Lagoons, often used in rural or spacious areas, rely on blowers for extended aeration. These blowers are typically located outdoors, necessitating resilience to environmental conditions. Inovair blowers are designed to withstand such outdoor applications, providing reliable performance. Since most lagoons are shallow and require low pressure, Inovair is able to utilize our in-house aerodynamicists and manufacturing experts to design impellers that operate reliably in pressures as low as 1 psig.

 

Case Study: Minonk, IL

 
The Minonk, Illinois wastewater treatment plant utilizes lagoons equipped with Inovair blowers. Despite being exposed to varying weather conditions, the blowers consistently delivered efficient aeration. This durability underscores the suitability of Inovair blowers for outdoor lagoon systems, ensuring long-term operational success.

Aeration with Dissolved Oxygen (D.O.) Control

In systems controlling aeration based on dissolved oxygen (D.O.) levels, blowers must operate across a range of airflows to meet fluctuating demands. Inovair blowers maintain high efficiency over a wide turndown range, adapting seamlessly to changing airflow requirements. The Inovair controls team, who have expertise with Most Open Valve and ABAC systems, are capable of assisting any utility looking to further enhance their operating system.

 

Case Study: New Holstein, WI

 
New Holstein, Wisconsin implemented D.O. control in their aeration basins with Inovair blowers. The blowers' ability to adjust to varying airflow demands resulted in precise D.O. levels and optimized energy consumption. This case demonstrates the efficiency and flexibility of Inovair blowers in D.O. controlled aeration systems.

Aerobic Digesters

Aerated digesters require blowers to handle higher levels of solids and varying liquid depths as water levels change during waste processing. Inovair blowers are capable of adapting to these pressure variations, ensuring consistent mixing and aeration.

 

Case Study: Valley Center, CA

 
The Valley Center, California facility utilizes aerated digesters with Inovair blowers. The blowers effectively managed the fluctuating liquid levels, providing consistent aeration and aiding in the efficient breakdown of solids. This adaptability highlights the capability of Inovair blowers to handle the dynamic conditions in aerated digesters.

Equalization Tanks

Equalization tanks use air for mixing and odor control, with varying liquid levels as the tanks fill and empty. Inovair blowers are adept at managing these changing levels, ensuring effective aeration and odor mitigation.

 

Case Study:

 
Equalization tanks equipped with Inovair blowers achieve efficient mixing and odor control. The blowers' ability to handle fluctuating liquid levels ensured optimal performance and environmental compliance. This case study illustrates the effectiveness of Inovair blowers in maintaining consistent operations in equalization tanks.
