APPARATUS FOR SEPARATING FLOATING AND NON-FLOATING PARTICULATE FROM A FLUID STREAM
First Claim
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 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.

Abstract
A fluid separation system includes a tank with a storage chamber for retaining floating and non-floating particulates. The tank includes a baffle for retaining floating particulates within the storage chamber and for directing flow out of the storage chamber. The tank also includes a bypass with an inlet flow control zone and an outlet flow control zone. The flow control zones are separated by a weir sized and positioned to regulate the fluid flow through a baffle port into the storage chamber. The weir also provides control of the flow rate at which incoming fluid is diverted directly through the bypass to the tank outlet rather than into the storage chamber. The baffle and/or the weir may be curved, and the baffle may include a complex curve, to aid in the smoothing of the fluid flow within the storage chamber to improve particulate separation.

21. A separation system for separating floating and non-floating particulate from a fluid, the system comprising:
-
a) a tank having a tank bottom and a storage chamber bottom spaced above the tank bottom and interior sidewalls, the interior side walls and the storage chamber bottom defining a storage chamber, an inlet at a first location on the interior sidewalls for receiving the fluid from an upstream conduit, and an outlet at a second location on the interior sidewalls for transferring the fluid to a downstream conduit;
b) a baffle having a bottom attached to the storage chamber 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;
c) a standpipe substantially centered within the storage chamber and establishing a passageway between the storage chamber and the outlet chamber, the outlet chamber for receiving fluid from the storage chamber and in communication with a region between the second side baffle wall and a portion of the interior sidewalls of the tank;
d) 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 outlet chamber and the outlet; and
e) 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 from the inlet to the outlet under relatively high fluid flows. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
