J. Ng, and S. L. Ong The principles of dissolved air flotation (DAF) which could potentially be applied to solve activated sludge foaming problems are discussed in the relevant context. Modification of existing Activated Sludge Plants (ASP) by incorporating a DAF facility in parallel with the aeration basin conceptually holds much promise as an alternative solution to foaming problems. A modeling approach with a summary simulation study of a real-world foaming problem has been presented for the purpose of exploring the conceptual feasibility of the DAF approach. It is proposed that this approach to foaming control that merits further laboratory and plant studies with a view to potential wide-scale applications.
