The First Defense® High Capacity by Hydro International is an advancement on the First Defense® enhanced vortex separator, available in Australia exclusively through Rocla.
The First Defense® High Capacity separator has internal components designed to remove and retain gross debris, total suspended solids (TSS) and hydrocarbons
Contaminated stormwater runoff enters the inlet chute from a surface grate and/or inlet pipe. The inlet chute introduces flow into the chamber tangentially to create a low energy vortex flow regime (magenta arrow) that directs sediment into the sump while oils, floating rubbish and debris rise to the surface.
