Pioneering Techniques in Aeration Design

The HERWIT Engineering team have collectively planned and designed multi-stage, positive displacement and single-stage turbo blowers and control systems for over 100 mgd of aeration systems.

How HERWIT aeration designs can improve your project:

· Improved aeration blower efficiency with variable frequency drives

· Improving aeration efficiency and Plant Operations

· Improving aeration blower efficiency with variable speed drives

· Control of aeration systems


Our Partners and engineers at HERWIT are experts in the field of aeration design, having authored numerous papers and spoken at national and local wastewater conferences. Other engineering firms and blower equipment manufacturers routinely consult with the HERWIT team on new integration techniques for aeration blowers, control valves, and control systems.

The firm pioneered the ‘Fixed Most Open Valve’ technique for controlling air flow in larger aeration systems. This system allows the lowest energy use possible while eliminating the hunting and visibility issues of other most open valve control systems. HERWIT Engineering was also the first firm to evaluate the application of variable speed magnetic couplings for aeration blower systems.
