An MRRDC Short Course – Biofilms: Principles and Advanced Model-Based Design

Have you ever wondered why a biofilm reactor behaves so much differently than activated sludge?  Struggled with the simulation speed and accuracy of your process model when a biofilm is inserted into the process flow diagram? This webcast will provide the fundamental knowledge to understand why a biofilm is different than suspended growth, and translate that into the requirements and expectations for a biofilm model.

Biofilm based technologies have been a part of the wastewater treatment field for over 100 years. Trickling filter systems were some of the first technologies utilized for the management of used water. While suspended growth technologies have become the dominant form of secondary treatment, biofilm based systems have seen a resurgence in impact over recent years with the development of the membrane aerated biofilm reactor (MBBR), integrated fixed film activated sludge (IFAS), and granular sludge systems. The complexity of biofilm systems, and the importance of mass transfer limitations in the design and operation of biofilm reactors, is a critical piece of knowledge for engineers and operators interfacing with biofilms. This webcast will provide an introduction to the fundamental difference of a biofilm system and a suspended growth system, and then describe the required differences in modeling approach.
