Performance Testing of Blowers for Wastewater and Industrial Applications

Blowers are critical to meeting process and energy objectives for wastewater and industrial facilities. Typically a significant capital expenditure, blowers are a major part of energy and operating expenses. Rigorous testing is essential for developing application data and for verifying equipment performance. This course delivers a comprehensive understanding of blower testing, from thermodynamic fundamentals to real-world implementation of test procedures. Participants will explore performance verification for both PD and centrifugal blowers, including instrumentation, data analysis, and specification strategies. With insights from over 40 years of industry experience, the course prepares attendees to confidently manage blower selection, testing, and reporting for high-stakes applications.

Learning Outcomes:

  • Identify the philosophy and fundamental concepts of blower testing
  • Understand and apply test procedures for PD and centrifugal blowers using industry-standard protocols.
  • Analyze thermodynamic properties and calculate performance metrics under varying conditions.
  • Specify appropriate testing requirements and reporting formats to meet project and regulatory needs.

Who Should Attend:

  • Consulting engineers
  • Operators of systems that use aeration blowers
  • Supervisors and managers who oversee systems that involve aeration
  • Regulatory staff at Federal agencies and military bases

Session 5: Reporting Test Results

  • Reporting requirements for raw data
  • Reporting requirements for specified data
  • Example calculations
  • Example report formats

 Objective: Develop an understanding of the calculations necessary for performance evaluation.

 Significance: Most tests require calculations to convert performance at test conditions to projected performance at specified operating conditions.

Session 6: Specification Considerations

  • Identifying test requirements
  • Power guarantees and penalties
  • Specifying critical performance parameters
  • Identifying components required within the test performance boundary
  • Defining reporting requirements and format

 Objective: Enable the attendee to specify the testing requirements suitable to project needs.
