This powerpoint presentation begins by presenting a diagram of a conventional drinking water treatment plant for surface water. Filtration complexity is outlined, along with independent variables in granular media filtration. The main topic, Application of Characteristic Reaction Time Concept to Filtration, presents topics that include: a first and second definition for "Characteristic Reaction Time"; Design of Continuous Flow Reactors with Characteristic Reaction Times; First Order Irreversible Reactions in Continuous Flow Reactors; filtration "reaction"; filtration modeling; Simplest Analytical Model: Yao, et al.; Tufenkji and Elimelech Model; Definition: Characteristic Removal Length; decisions; Data from Dual Media Alum Plants; and, Problems with Current Design Guideline.
