Abstract
Abstract An improved settler assembly comprising a plurality of inclined passages of chevron cross-sectional configuration. The chevron configuration provides a higher critical flow rate than for passages of equal area and length but of conventional crosssectional configuration such as square, circular, hexagonal and the like. A method of separating suspended material from a liquid is disclosed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
11 words
The apparatus of claim 1 wherein said throughrunning passages are parallel.
Claim 2
Dependent Claim
21 words
The apparatus of claim 1 wherein said throughrunning passages are radially outwardly disposed with respect to the axis of said assembly.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1 wherein said effluent end of said assembly is on a horizontal plane above said influent end and said liquid stream is directed upwardly through said passages.
Claim 4
Dependent Claim
37 words
The apparatus of claim 4 wherein said bottom ''''V'''' shaped wall of said passages defines a groove wherein suspended material in said liquid having a density greater than said liquid settles therefrom and accumulates in said groove.
Claim 5
Dependent Claim
49 words
The apparatus of claim 4 wherein said assembly is disposed at an angle greater than the angle of repose for said material settled from said liquid whereby said settled material moves in a direction counter to the liquid flow and is discharged from said influent end of said assembly.
Claim 6
Dependent Claim
28 words
The apparatus of claim 1 wherein said effluent end is on a horizontal plane below said influent end and said liquid stream is directed downwardly through said passages.
Claim 7
Dependent Claim
37 words
The apparatus of claim 7 wherein said upper V shaped wall of said passages defines a groove wherein suspended material in said liquid having a density less than said liquid rises therefrom and accumulates in said groove.
Claim 8
Dependent Claim
49 words
The apparatus of claim 7 wherein said assembly is disposed at an angle greater than the angle of repose for said material settled from said liquid whereby said settled material moves in a direction counter to the liquid flow and is discharged from said influent end of said assembly.
Claim 9
Dependent Claim
22 words
The apparatus of claim 1 wherein said settler assembly is in the form of a rhomboid whereby said throughrunning passages are equi-length.
Claim 10
Dependent Claim
19 words
The apparatus of claim 1 wherein said settler assembly is frusto-conical in form and said throughrunning passages are equi-length.
Claim 11
Dependent Claim
17 words
The apparatus of claim 1 wherein said internal angle defining said groove ranges between 10* and 179*.
Claim 12
Independent Claim
105 words
A method for separating settleable suspended material from a liquid comprising the steps of providing a settler assembly having an influent end and an effluent end and comprising a plurality of inclined passages of chevron cross-sectional configuration, introducing liquid containing settleable suspended material to the influent end of said settler assembly, flowing said liquid through said passage at a flow rate of not more than the critical flow rate of said passage whereby material suspended in said liquid settles out of said liquid in said passage while said liquid is flowing therethrough and leading said liquid away from said effluent end of said settler assembly.
Claim 13
Dependent Claim
55 words
The method of claim 13 wherein said passages are inclined at an angle greater than the angle of repose of said material in said passage and said material settled in each of said passages flows through said passages counter to the flow of said liquid and leaves said settler assembly at the influent end thereof.
Claim 14
Dependent Claim
18 words
The method of claim 13 wherein said passages are inclined at an angle of 60* to the horizontal.
Claim 15
Dependent Claim
32 words
The method of claim 13 wherein the settleable suspended material has a specific gravity greater than said liquid and said influent end of said inclined settler assembly is below said effluent end.
Claim 16
Dependent Claim
31 words
The method of claim 13 wherein the settleable suspended material has a specific gravity less than said liquid and said influent end of said inclined assembly is above said effluent end.
Claim 17
Dependent Claim
49 words
The method of claim 13 wherein said infLuent end of said inclined settler assembly is above said effluent end and said liquid and said material which has settled out of said liquid flow co-currently through said passages and said material leaves said settler assembly at the effluent end thereof.
