Abstract:
1. A separation system for separating floating and non-floating particulate from a fluid, the system comprising: a) a tank having a bottom and interior sidewalls establishing a storage chamber, an inlet for receiving the fluid, and an outlet for transferring the fluid out of the tank; b) a baffle having a bottom, a first side baffle wall, a second side baffle wall and a baffle port to allow fluid entering the tank to pass from behind the baffle into the storage chamber, the baffle positioned within the tank, the bottom of the baffle spaced above the bottom of the tank; c) a bypass including an inlet flow control means on the second side baffle wall between the inlet and the baffle port; and d) a weir positioned between the inlet flow control means and the outlet, the weir configured to divert fluid from the inlet to the baffle port under relatively low fluid flows and to divert one portion of the fluid from the inlet to the baffle port and to allow the remaining portion of the fluid to flow from the inlet to the outlet under relatively high fluid flows.
