The Legacy of IntensAer: A Deeper Dive

This expanded look at the IntensAer radial surface aerator, once offered by Walker Process Equipment, delves into specific aspects of its design, application, and impact on the wastewater treatment industry.

Chapter 1: Techniques

IntensAer employed a unique radial flow aeration technique. Unlike other surface aerators which might use a linear or circular pattern, the IntensAer's radial design, with its rotating arms extending from a central hub, allowed for a more even distribution of oxygen across the wastewater surface. This was achieved through the carefully engineered blade angles and rotational speed. The adjustable blade angles were a key feature, allowing operators to fine-tune the aeration intensity based on several factors, including the volume of wastewater, its organic loading, and the desired dissolved oxygen (DO) levels. The radial flow itself promoted mixing, assisting in the even distribution of the oxygenated water throughout the treatment basin. The design also minimized the creation of dead zones where oxygen transfer might be inefficient. This efficient mixing contributed to the overall effectiveness of the biological processes within the wastewater treatment system.

Chapter 2: Models

While specific model numbers for the IntensAer are not widely documented publicly, it's likely that Walker Process offered variations in size and capacity to suit different applications. The core design principles remained consistent across models, but the number of arms, the diameter of the unit, and the power requirements would have varied to accommodate the scale of the wastewater treatment plant. Larger models would have been designed for higher flow rates and larger treatment basins, while smaller units were suitable for smaller applications or as supplementary aeration in existing systems. This scalability was a significant advantage, as it allowed the IntensAer to be integrated into a variety of wastewater treatment projects. The lack of readily available model specifications reflects the age of the technology and the transition away from this particular aerator design.

Chapter 3: Software

IntensAer itself didn't incorporate software in the way modern aeration systems might. There wasn't onboard process control or data logging capabilities. However, the performance of the IntensAer would have been factored into the overall process control strategy of the wastewater treatment plant. This would have involved manual monitoring of DO levels, adjustments to the aerator's blade angles, and monitoring of power consumption. Data on the system's performance – DO, power usage, and flow rate – would have been collected manually and used to optimize the system's operation. Modern supervisory control and data acquisition (SCADA) systems, which were likely not commonly used at the time of IntensAer's prominence, would have been used to monitor and control the wider treatment plant where it was integrated.

Chapter 4: Best Practices

Effective operation of the IntensAer relied on several best practices:

• Regular Maintenance: This included inspecting the blades for wear and tear, ensuring proper lubrication of moving parts, and checking for any signs of damage or corrosion.
• Optimized Blade Angle Adjustment: Regular monitoring of DO levels and adjusting the blade angles to optimize oxygen transfer based on prevailing conditions was crucial.
• Effective Basin Design: The design of the wastewater treatment basin itself played a significant role in the overall effectiveness of the IntensAer. Sufficient depth and appropriate baffling were necessary to ensure proper mixing and prevent short-circuiting.
• Preventative Maintenance Scheduling: A proactive maintenance schedule, including regular inspections and component replacements as needed, helped to ensure the longevity and efficiency of the IntensAer.

Chapter 5: Case Studies

Unfortunately, publicly available case studies specifically detailing the performance of IntensAer are scarce. The lack of detailed case studies likely stems from the age of the technology and the proprietary nature of such data. However, general information about radial surface aerators, which share similar operational principles, can be found. These studies often showcase the efficiency of radial aerators in terms of energy consumption and oxygen transfer. A thorough search through archives of industry publications and potentially contacting former Walker Process customers might yield some specific data on the IntensAer's performance in specific wastewater treatment applications. To find such data, one would likely need to consult archival industry journals or contact engineers who were involved with the design, installation, or operation of wastewater treatment systems that utilized the IntensAer.
