Continuous Long Term Simulations for Evaluating Storage Treatment Design Options of Stormwater Filters

Abstract

Stormwater media filters are used to treat a variety of pollutants at different source areas. These can range from being as simple rain gardens or biofilters containing soils or special media, to proprietary devices. Historically, sand filters and sand-peat filters were some of the earliest filters used for stormwater control. Austin (1988), Galli (1990), Shaver (1994, Claytor and Schuler (1996), and Urbonas (1999) all include descriptions and performance information for these fundamental stormwater filtration systems. These filters have been used to treat a variety of conventional stormwater pollutants, mostly focusing on suspended solids and nutrients. Continued research has examined additional media and expanded our understanding of stormwater media filters. Clark and Pitt (1999) include an extensive review of different media, designs, and expected performance. A large number of proprietary stormwater filters are also now available and usually include cartridges of specialized media that can target specific classes of stormwater contaminants. Descriptions of many of these devices have been described at technical conferences, especially the annual StormCon conference (http://www.stormcon.com/) where venders have extensive exhibits showcasing these filters. The International BMP Database has much data describing actual field performance for a wide range of stormwater filters (http://www.bmpdatabase.org/).

Permeable Pavers Designed for Rapid Renewal by Considering Sweeper Mechanics: Initial Field Tests

“…Several models have been developed for the design of low impact developments (LIDs) that include PICP (Myllyoja et al 2001;Sutherland et al 2002;Rivard et al 2004;ICPI 2009;Rossman 2010;Zhang et al 2010;Pitt et al 2011;CHI 2018). Readers are reminded to check whether the models being considered include coding for processes related to the restoration of infiltration capacities.…”
