Description:
A full-scaled Multi-Chambered Treatment Train (MCTT) stormwater treatment system was tested in Taiwan during the spring and summer of 2007. The MCTT was installed in a parking lot in Ping-Lin, Northern Taiwan. The site is 85% impervious and has a drainage area to the MCTT unit of 0.1 ha. The unit was designed to treat the first 10 mm of runoff from the site. A fourth chamber was added to the overall design to serve as an extra chamber for settling and convenience of sampling. A total of six storm events were sampled. Parameters analyzed included total suspended solids (SS), chemical oxygen demand (COD), ammonia-nitrogen (NH3-N), total phosphorus (TP), lead (Pb), copper (Cu), zinc (Zn), oil/grease (O/G) and fecal coliform. Pollutant removal was calculated with both the sum of loads (SOL) and the event mean concentration (EMC) methods. Results showed the following average removal efficiencies: SS ≈ 90%; COD ≈ 45%; NH3-N ≈ 60%; TP ≈ 50%; Pb ≈ 60%; Cu ≈ 65%; Zn ≈ 85%; fecal coliform ≈ 80%, and O/G ≈ 45%. These results are similar to those obtained for several field tests conducted in Alabama, Wisconsin and California in the US.
