Membrane and media filters are more commonly used as "stand alone" water quality treatment practices, but may also be used downstream of LID facilities or treatment trains to enhance removal of sediment and other targeted pollutants (e.g., nutrients, metals) where warranted by receiving water sensitivity.
Membrane and media filters are more commonly used as "stand alone" water quality treatment practices when space for surface practices is not available, but may also be used downstream of LID facilities or treatment trains to enhance removal of sediment and other targeted pollutants (e.g., nutrients, metals) where warranted by receiving water sensitivity.
