Title: HYDRODYNAMIC SEPARATOR
Abstract:
A separator unit includes a tank defining an internal volume and having an inlet and an outlet. A deck within the tank separates the tank into an upper chamber and a lower chamber. A weir at an upper side of the deck defines an inlet side atop the deck for receiving an influent liquid and an outlet side atop the deck, with a first opening through the deck on the inlet side for delivering liquid down into the lower chamber, and a second opening through the deck on the outlet side for delivering liquid from the lower chamber back up into the upper chamber. The separator includes one or more of an integrated drop pipe assembly with a dispersal manifold, a riser path with a vortex disrupting vane and/or a second opening configuration that is at the perimeter of the deck.
