Simple treatment train equations that apply the pollutant removal efficiency of the downstream treatment practice to the fraction of load remaining after passing through the upstream treatment treatment practice, or those that assign downstream practices half the removal efficiency of the upstream practice are not recommended. Instead, the configuration and type of treatment train should be considered on a case by case basis, with consideration for changes in influent runoff concentration/composition and runoff volume as water drains through the different practices. Some examples are provided in the sections below.
