  2. Typical Applications 1. Wastewater Treatment 2. Landfill Gas Extraction 3. Sulphur Recovery 4. Process Gas Boosting 5. Carbon Black 6. Fluidized Bed 7. Flue Gas De-Sulferization 8. Others

  3. Typical Applications Wastewater Treatment

  4. Wastewater Basins

  5. 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. Blowers in Wastewater

  6. 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.

  7. Typical Applications TYPES OF AERATION PROCESSES • Coarse Bubble • Fine Bubble • Jet • SBR • Mechanical Aerators

  8. Typical Applications Course Bubble Jet Aeration Sequence Batch Reactor (SBR) Fine Bubble

  9. Oxygen Transfer Performance Mixing Performance Efficiency Maintenance Reliability Installation Costs Aeration Processes:Comparison Factors

  10. EFFICIENCY COMPETITIVE PRICING LOW MAINTENANCE WHY UTILIZE A MULTISTAGE (MS) CENTRIFUGAL ? DURABLE SYSTEM FRIENDLY VARIABLE FLOW & PRESSURE

  11. 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.
