The City of De Pere Wastewater Treatment Facility, which provides tertiary treatment services for the City of De Pere, is dedicated to providing its’ customers with the best service and lowest cost treatment while maintaining harmony with the environment.  For the last seven years, Facility Manager Michael Kersten has been replacing outdated/failing equipment and renovating treatment systems all without increasing treatment costs.  Recently, Kersten turned to Crane for a new HST blower system from ABS Pumps, Inc. of Meridan, CT.  The new blower system will optimize control of the process while realizing a savings in power costs of $40,000.00 to $50,000.00 per year….and is the first installation of its kind in the U.S.

ABS Pumps’ HST Integral turbo-compressor is a high-speed centrifugal air compressor that uses an integral motor and compressor with a variable speed drive to match air compressor output with demand.  The motor and compressor are a single rotor design that operates at speeds up to 25,000 rpm, which is possible since there are no bearing or friction components in the compressor.

At this time, the only HST turbo-compressor installations are in Europe, making this the first installation in the United States. 

The City of De Pere Wastewater Treatment Facility has received the USEPA Regional Award for excellence in operations and maintenance, and the WDNR Brogan Award for excellence in environmental achievement.  Other recent awards include the National Energy Watch Award, the Clean Bay Backer Award, and the Brown County Conservation Alliance Award.
