Efficiency of a continuous deflective separation (CDS) unit in removing contaminants from urban stormwater
The weighted average concentration (WAC) of total suspended solids (TSS) in stormwater effluent from a continuous deflective separation (CDS) unit in Port Jackson (Australia) catchment was reduced by an average 28% during six high-flow events, but some TSS was released during turbulent, high-flow events. The average removal efficiency of metals Cr, Cu, Pb Mn, Ni, Zn and Fe varied considerably (−49% for Pb and +10% for Mn), whereas Ni and Zn were inefficiently removed by the device. Average concentrations of TKN, NOx and TP were similar at both in- and out-flow points and faecal coliforms counts were slightly reduced.
