- Abstract:
- Rotating Biological Contactor (RBC) is one of the ancient and outstanding technologies in biological wastewater treatment. In its design and practical operation, the two important parameters commonly used are the minimum speed of the contactor and the motor power. However, the formulas for minimum speed and motor power calculation are quite different specified in the current Water Supply and Drainage Design Manual (Vol.5, 3rd Ed.), Water Supply and Drainage Professional Qualification Examination Textbook for the National Survey and Design Registered Public Equipment Engineers (2020), Wastewater Engineering (Vol. Ⅱ, 5th Ed.) and other important books, which makes it difficult for readers to judge which calculation formula is a reasonable expression, thus causing confusion in teaching, scientific research and design. To solve this problem, the correct formula for calculating the minimum speed and the motor power of RBC was determined by consulting the historical documents and deducing the formula again.
