Dispersion Model for Waste Stabilization Ponds
Publication: Journal of Environmental Engineering
Volume 111, Issue 1
Abstract
The partially‐mixed or dispersed‐flow equation is proposed for use in pond design for organic and bacterial reductions. This equation considers the effects of hydraulic detention time (θ), reaction rate coefficients, and the dispersion factor including short‐circuiting, and other hydraulic transport processes which influence the pond's performance. Some hydraulic models of dispersion were reviewed. A dispersion prediction formula for ponds is proposed which relates the value of the dispersion number to θ, kinematic viscosity, and the pond's geometric shape, i.e., length, width, and depth.
