Aeration and Blower Design for Biological Wastewater Treatment
8 hours
Detailed Title:
Master oxygen transfer principles, blower selection, and air system design for optimized biological treatment performance.
Course Description:
Aeration is the heartbeat of biological treatment and the most energy consuming unit in wastewater treatment plants. Then, blower selection and air system design can make or break project applicability and process efficiency. This course gives engineers, operators, and designers the complete picture of how oxygen is transferred, consumed, and managed within aeration systems.
From BOD demand to Standard Oxygen Transfer Efficiency (SOTE) and Actual Oxygen Requirement (AOR), you’ll learn how to balance biology, air delivery, and power consumption. The course explores diffuser types, aeration grid layouts, blower power calculations, and correction factors like α, β, θ, and F to size your system accurately and avoid common pitfalls.
By combining theory, real-world rules of thumb, and practical design tips, this course equips you to work confidently on activated sludge systems, lagoons, MBRs, or aerated tanks—whether for new builds or upgrades.
