The Partners and engineers at Herwit have authored
numerous papers and made presentations at both national and local
wastewater conferences on proper aeration design.Mr. Harris has been consulted by other engineering firms and blower
equipment manufacturers on new integration techniques for aeration
blowers, control valves, and control systems.
Harris also developed a new techniques for controlling air flow called the
“Fixed Most Open Valve” control system for larger aeration systems.This system allows the lowest energy use possible while eliminating
the hunting and instability issues of other most open valve control
Mr. Harris has had his Aeration Control
system published in the National Water Environment Technology
Together, Mr. Harris and Mr. Gardner have
planned and or designedmulti
stage, positive displacement, and single stage turbo blowers and control
systems for over 100 mgd of aeration systems.
Herwit was the first Engineering firm to evaluate the application of
variable speed magnetic couplings for aeration blower systems.
