A pollutant removal prediction tool for stormwater derived diffuse pollution

open access: yesWater Science and Technology, 2008
This report describes the development of a methodology to theoretically assess the effectiveness of structural BMPs with regard to their treatment of selected stormwater pollutants (metals, polyaromatic hydrocarbons and herbicides). The result is a prioritisation, in terms of pollutant removal efficiency, of 15 different BMPs which can inform ...

Diffusion of reacting pollutants

open access: yesApplied Mathematical Modelling, 1980
Abstract The Boltzmann equation including reactive scattering terms is the correct description of the combined transport-reaction process. A suitable parameterization transforms it into a set of differential equations governing the macroscopic mass balance.
