Whitepaper Features Aeration Blowers for Wastewater


Complete Overview Provides Guidance For Using The Correct Blower Technology

Coatesville, Pennsylvania, Oct. 1, 2009 - A new, in-depth whitepaper featuring several
blower technologies was developed and released by Aerzen USA entitled Aeration
Blowers in the Wastewater Industry in North America". The paper presents four types of
blowers: two dynamic and two positive displacement machines. By presenting how each
technology has its place, a comparison is made specifically based on the treatment of
wastewater. Taken into account are the daily and seasonal swings in oxygen demand,
fouling and aging of diffusers, air flow control and turndown capabilities, total blower
efficiency and energy consumption over time, mode of operation, blower accessories, and
plant set-up.

"The intent of this paper is to provide information that will help the engineer
appropriately define both the design and the evaluation criteria of various blower
technologies. The real total costs of ownership over time should guide the selection
process." states Aerzen USA President, Pierre Noack.

The paper takes a pragmatic approach by presenting ways to minimizing energy usage:
right-sizing, aeration control, defining the operating range and matching the blower
technology to the application, and comparing operating data over time. At the same time
the paper recommends engineers to exercise due professional diligence and to select the
most suitable aeration blower technology based on a relevant comparison.

As the main consumer of electricity in a wastewater treatment plant, the aeration system
greatly influences the overall cost of operation, that in the long-term by far exceed the
initial investment cost.

Several blower technologies can be chosen from and it therefore behooves the engineer to
accurately evaluate the characteristics of the aeration blowers and carefully interpret
some of the claims made by various manufacturers.
The most energy efficient solution must be based on actual conditions that, in reality, will
vary over an extended period of time.

Noack elaborates, "The economical operation of a wastewater treatment plant depends
largely on the design and the interplay of the aeration and process controls. Moreover,
the human factor and the management objectives are at the heart of the plant's reality and
should also be taken into consideration. Selection and thoughtful integration of all the
subsystems is of paramount importance."

Aerzen USA will be giving presentations on October 12th through 14th on the whitepaper
at the upcoming tradeshow:
