Overview

Wastewater treatment plants play a pivotal role in maintaining the ecosystem. But the question arises: can they be made more efficient, more reliable, and eco-friendly? The case study on a WWT plant, enhanced by CALMS optimization, uncovers this potential.

Objective

Replacement of a standard frequency-driven 500 HP roots blower with a more compact and efficient 300 HP turbo blower in a WWT plant.

Results

  1. Space Efficiency: The new system required 30% less space, making it ideal for infrastructural considerations.
  2. Noise Reduction: There was a significant noise level drop to 82dB @ 1 m from the prior 105 dB, making the environment more conducive for workers and less disruptive for nearby surroundings.
  3. Energy Consumption: Energy consumption decreased by over 27%, reflecting major cost savings and a step toward sustainability.
  4. Temperature Control: The discharge temperature stood 36 °F lower than with the roots blower. This led to an increase in aerated water temperature by less than 5.4 °F, ensuring controlled water conditions.
  5. Integrated System Benefits:
    • Integrated frequency driver simplifies the operation.
    • The oil-less system assures 100% oil-free air, mitigating environmental impacts.
    • Precise control prevents excessive aeration, safeguarding against potential system damages.

Technology Enhancements

CALMS introduced advanced hardware, software, and cloud computing solutions. These innovations ensure real-time online monitoring and auditing of compressed air systems.

  1. 3-in-1 System Integration: Merging the Compressed Air Remote Monitoring System, Data logger, and PLC Control System facilitates a holistic approach to data analysis.
  2. Key Benefits:
    • Time & Cost Efficiency: Operational times are reduced, and expenses are slashed.
    • Optimized Energy Efficiency: It’s not just about saving energy but utilizing it in the most effective way.
    • Enhanced Reliability: System and machinery reliability is significantly boosted, ensuring longer, hassle-free operational lifetimes.

Conclusion

Embracing CALMS optimization in the WWT plant presented transformative changes. The combination of space-saving, noise reduction, and energy optimization, paired with advanced technological integrations, showcased that eco-friendly efficiency isn’t just a vision; it’s achievable.
