Treatment Wetland for Overflow Stormwater Treatment: The Impact of Pollutant Particles Size

The problem of stormwater treatment in urban areas has become increas- ingly crucial. It has been widely recognized that both mechanical and biological treatment of stormwater is necessary to protect surface water against pollution. Moreover, technology must be applied to ensure effective treatment in changing hydraulic conditions and to serve, to the extent possible, as a retention volume. Treatment wetland (TW) could be one of the best solutions for stormwater treat- ment. In this paper, we describe the problem of removing suspended solids in a two-stage TW(pond and horizontal subsurface flow bed).We also discuss the result of particle size distribution in compartments of the analyzed TW during different weather conditions.
