Abstract

With the establishment of how to design a PSM- and site-specific P removal structure, this chapter is intended for those readers who have the Phrog (Phosphorus Removal Online Guidance) software, or would like to learn about the software. The Phrog software allows the user to quickly design and examine many different options for a structure design at a specific site and PSM to be utilized. The user simply inputs the required PSM information, site assessment information, and the targets: retention time, desired peak flow rate, lifetime, and P removal. The resulting output consists of the required mass and orientation of the PSM, the required number of drainage pipes, and a table that lists the annual P removal until the PSM is no longer effective at removing P. In addition, the ability of the software to predict the performance, i.e. lifetime and P removal, for an already existing structure will also be explained and illustrated. The use of the software for achieving these purposes in a variety of different situations and types of P removal structures will be illustrated with software screenshots of both inputs and outputs. Examples will include design of a confined bed runoff filter, ditch filter, subsurface tile drain filter, bio-retention cell, surface inlet, and waste-water treatment plant.
