Wastewater treatment processing simulation technology using Activated Sludge Model

In developing design support software and operation support software for advanced wastewater treatment plants, JFE Engineering uses the "Activated Sludge Model" advocated by International Water Association (IWA). As examples of development, this report describes model construction and verification for design support of oxidation ditch (OD) facilities and model construction for operation support of an advanced treatment process with a microbiol carrier, together with an example of practical application.
