Abstract
Abstract An apparatus for separating floating and non-floating particulates from drain water wherein said apparatus includes a first chamber for collecting non-floating particulates, a second chamber for collecting floating particulates, and a third chamber through which treated drain water can be discharged from the apparatus. An inlet pipe for introducing drain water into the first chamber is provided tangential to the first chamber to provide a vortex flow of drain water into said first chamber. An outlet pipe providing flow of drain water from the first chamber to the second chamber has an inlet at the vortex of drain water flow in the first chamber and an outlet that is spaced a predetermined distance from the floor of the chamber.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
145 words
An apparatus for separating floating and non-floating particulates from drain water, comprising: a first chamber for collecting non-floating particulates, including a first inlet for directing drain water tangentially into the first chamber to provide a vortex flow of drain water within said first chamber, a second chamber for collecting floating particulates, an outlet pipe providing flow of drain water from the first chamber to the second chamber comprising a second inlet at the vortex of drain water flow in the first chamber and an outlet in the second chamber spaced a predetermined distance from a floor, and a third chamber through which treated drain water can be discharged from the apparatus, the third chamber in fluid communication with the second chamber through an opening between the second chamber and the third chamber, the opening offset from the axis of the outlet in the second chamber.
Claim 2
Independent Claim
145 words
An apparatus for separating floating and non-floating particulates from drain water, comprising: a first chamber for collecting non-floating particulates, including a first inlet for directing drain water tangentially into the first chamber to provide a vortex flow of drain water within said first chamber, a second chamber for collecting floating particulates, an outlet pipe providing flow of drain water from the first chamber to the second chamber comprising a second inlet at the vortex of drain water flow in the first chamber and an outlet in the second chamber spaced a predetermined distance from a floor, and a third chamber through which treated drain water can be discharged from the apparatus, the third chamber in fluid communication with the second chamber through an opening between the second chamber and the third chamber, the opening offset from the axis of the outlet in the second chamber.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 , wherein the outlet extends a predetermined distance into the second chamber.
Claim 4
Dependent Claim
25 words
The apparatus of claim 1 , wherein the outlet in the second chamber is above the opening between the second chamber and the third chamber.
Claim 5
Dependent Claim
33 words
The apparatus of claim 1 , the first chamber further comprising a horizontal plate disposed below the level of the first inlet to prevent non-floatable particles from becoming re-entrained in the drain water.
Claim 6
Dependent Claim
32 words
The apparatus of claim 4 , wherein the horizontal plate further comprises an opening concentric with a vertical axis of the first chamber to allow the non-floatable particles to pass there through.
Claim 7
Dependent Claim
34 words
The apparatus of claim 1 , wherein the outlet pipe terminates at a barrier that separates the second and the third chambers, the drain water exiting the outlet pipe through an upwardly facing opening.
Claim 8
Dependent Claim
36 words
The apparatus of claim 1 , wherein the outlet pipe further comprises an opening spaced a predetermined distance below the first inlet to allow drain water to enter the outlet pipe during lower flow rate periods.
Claim 9
Dependent Claim
42 words
The apparatus of claim 1 , further comprising a conduit extending from a third inlet in the first chamber to a second outlet in the third chamber to allow drain water to flow during peak storm flows, thereby bypassing the second chamber.
Claim 10
Dependent Claim
18 words
The apparatus of claim 8 , wherein the third inlet extends a predetermined distance into the first chamber.
Claim 11
Dependent Claim
22 words
The apparatus of claim 8 , wherein the third inlet is formed at an angle to the longitudinal axis of the conduit.
Claim 12
Dependent Claim
29 words
The apparatus of claim 1 , further comprising a plurality of vortex breakers located along a floor of the first chamber to aid in the trapping of non-floatable particles.
Claim 13
Dependent Claim
24 words
The apparatus of claim 1 , wherein an anti-vortex device is provided at the second inlet to provide quiescent flow into the second chamber.
Claim 14
Dependent Claim
48 words
The apparatus of claim 12 , wherein said anti-vortex device is for controlling the velocity of swirl or cyclonic effect of the drain water entering the outlet pipe whereby to negate the tendency for trapped non-floating particulate from being drawn into said outlet pipe during peak storm flows.
