Abstract
This paper presents a mathematical and pilot-scale empirical development and quantification of a unique zero-order Flux model. Iron concentration was found to depend on surface release flux (Km), pipe material, pipe geometry and hydraulic retention time. Flux is a function of pipe material, water chemistry and Reynolds Number. In the galvanized iron, Km (mg Fe/m2-d) has values of 1.99 and 0.0045(Re -2000) + 1.99 under laminar and turbulent flow conditions, respectively. Similarly, Km was found to be 4.16 and 0.009(Re -2000) + 4.16 for unlined cast iron pipe under laminar and turbulent flow conditions respectively.
