Blowers in Wastewater As Biochemical Oxygen Demand requirement changes in wastewater treatment, Gardner Denver multistage centrifugal blowers adjust easily. The Gardner Denver blowers save energy by eliminating the need for blowoff systems. Gardner Denver centrifugal blowers in wastewater service are designed for direct connection to an electric motor with a non-lubricated flexible drive coupling. APPLICATIONS Gardner Denver CF SBU March, 2004
BALANCING B. O. D. (Biochemical Oxygen Demand) • Too little Dissolved Oxygen causes the microorganisms to perish resulting in a septic process. • Too much Dissolved Oxygen is wasteful & can cause frothing. • Blower flow control is critical. APPLICATIONS Gardner Denver CF SBU March, 2004

ADVANTAGES OF MULTISTAGE CENTRIFUGAL BLOWERS • Flexibility - MS Blowers allow variable flow capability without a VFD, critical for maintaining sufficient amounts of dissolved oxygen at the minimum and maximum air requirement levels. • Efficiency - MS Blowers maintain efficiency throughout their useful life. Additional energy savings are gained by inlet throttling and using custom design control schemes. • Low Maintenance - With L-10 bearing life design and no wearing parts, MS Blowers operate virtually maintenance free. (Periodic lubrication) • Low Noise - Most MS Blowers operate below 85 dba at 1 meter. APPLICATIONS Gardner Denver CF SBU March, 2004
