Assessment and development of design criteria for a hybrid stormwater treatment system

摘要

Continuous monitoring of stormwater best management practices (BMPs) is essential to fully understand their efficiency and capacity. In this study, a hybrid mobile stormwater BMP system was assessed, and the design implications to remove and reduce pollutant loads and large volumes were observed by conducting a series of storm event monitoring. The water balance attributed by a variety of rainfall depth affected the pollutant removal capacity of the system. Treatment units of the hybrid system showed effectiveness in reducing particulates. However, only appreciable pollutant reductions for TN and heavy metal constituents were observed. Results from the water balance in the system aided the development of design criteria for further improvement in the design of the system.
