Wastewater Treatment Odor Control
Wastewater treatment plants must be good urban neighbors
by ensuring that odors from their processes are minimized.
Hydrogen sulfide, or H2S, forms in the early processing
stages, and is typically the primary cause of odor emissions.
Large urban wastewater plants have a growing number of
odor treatment options from which to choose – many of which
require the use of robust and reliable air moving equipment.
Power generation is a complex process. It takes an act of
congress (figuratively and literally) to build, operate and
maintain a power generation facility. Ventilation equipment
should not add to this complexity. Rather, the equipment
should be tough enough to avoid operational failure and to
minimize installation and repair work. The rugged, high-
performance fans Aerovent provided to a state-of-the-art
hybrid energy center, were ideal for the task. Aerovent was
chosen for this project because of their reputation for building
large custom fans for extreme industrial applications.
A steel plant located in the Midwest produces carbon,
stainless, and electrical steels; hot and cold-rolled steel; as
well as aluminum-coated stainless steel. The plant’s hot strip
mill building is a large facility where slabs of steel are rolled
into steel coils. The building is currently ventilated with
upblast roof exhaust fans. Access for routine maintenance is
difficult, and consequently, the roof exhaust fan bearings are
beginning to fail.
Hydroelectric Power Station
The Beauharnois Hydroelectric Power Station on the Saint
Lawrence River in Quebec, Canada is one of the largest
hydroelectric power plants in the world. Located 25 miles
southwest of Montreal, the main building containing the
power station is constructed atop the Beauharnois Dam.
Hydro-Quebec, owner and operator of the dam, brought in
Dessau, one of Canada’s largest engineering-construction
firms, to revamp and modernize the power plant which stretches
nearly a half mile across the Saint Lawrence River and contains
38 hydroelectric turbines capable of generating up to 1,903 MW
of electrical power.
