Patent ID: 6991114

Claim:
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 to define a storage chamber, an inlet at a first location on the interior sidewalls for receiving the fluid, and an outlet at a second location on the interior sidewalls 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 port through from the first side baffle wall to the second side baffle wall, the baffle connected to the interior sidewalls of the tank, the bottom of the baffle spaced above the bottom of the tank to establish a storage chamber outlet for fluid within the storage chamber to pass along the second side baffle wall to the outlet; c) a bypass including an inlet flow control means on the second side baffle wall between the inlet and the port of the baffle and an outlet flow control means on the second side baffle wall between the storage chamber outlet and the outlet; and d) a weir positioned between the inlet flow control means and the outlet flow control means, 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.
