Abstract
Abstract Arrangement for cleaning of waste water by application of rotating biocontactors utilizing tubular biocontactors open at both ends wound on a rotating cylindrical frame adapted to be alternatively submerged below and raised above the level of the waste water, combining thereby the effect of cleaning by biocontact and of efficient aeration of the waste water.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
97 words
An apparatus for cleaning waste water comprising: a tank for holding waste water; a rotatable shaft supported within said tank; a face plate mounted near each end of said shaft; a plurality of longitudinal bars spaced from each other and having their terminal portions secured adjacent to the periphery of said face plates; and at least one continuous tubular biocontactor wound at least partially around said longitudinal bars, said tubular biocontactor having an open inlet end and an open outlet end with both ends of the tubular biocontactor facing in the direction of rotation of said shaft.
Claim 2
Independent Claim
97 words
An apparatus for cleaning waste water comprising: a tank for holding waste water; a rotatable shaft supported within said tank; a face plate mounted near each end of said shaft; a plurality of longitudinal bars spaced from each other and having their terminal portions secured adjacent to the periphery of said face plates; and at least one continuous tubular biocontactor wound at least partially around said longitudinal bars, said tubular biocontactor having an open inlet end and an open outlet end with both ends of the tubular biocontactor facing in the direction of rotation of said shaft.
Claim 3
Dependent Claim
18 words
An appparatus for cleaning waste water as defined in claim 1, further including means for rotating said shaft.
Claim 4
Dependent Claim
22 words
An apparatus for cleaning waster water as defined in claim 2, wherein said means for rotating said shaft includes an electric motor.
Claim 5
Dependent Claim
39 words
An apparatus for cleaning waste water as defined in claim 2, wherein a plurality of continuous tubular biocontactors are spaced about said spaced longitudinal bars so as to provide a uniform stress on the means for rotating the shaft.
Claim 6
Dependent Claim
49 words
An apparatus for cleaning waste water as defined in claim 1, wherein a portion of said continuous tubular biocontactor is folded upon itself around said inlet end of said tubular biocontactor, such that said outlet end of said tubular biocontactor faces in the direction of rotation of said shaft.
Claim 7
Dependent Claim
30 words
An apparatus for cleaning waste water as defined in claim 1, wherein at least a part of said tubular biocontractor extends in an axial direction with respect to the shaft.
Claim 8
Dependent Claim
36 words
An apparatus for cleaning waster water as defined in claim 6, wherein said part of said tubular biocontactor extending in an axial direction with respect to the shaft is the central portion of said tubular biocontactor.
Claim 9
Dependent Claim
35 words
An apparatus for cleaning waste water as defined in claim 6, wherein said part of said tubular biocontactor extending in an axial direction with respect to the shaft extends to substantially the opposite face plate.
Claim 10
Dependent Claim
44 words
An apparatus for cleaning waste water as defined in claim 6, wherein the inlet end of said tubular biocontactor is located adjacent one of said face plates and the outlet end of said tubular biocontactor is located adjacent the other of said face plates.
Claim 11
Dependent Claim
28 words
An apparatus for cleaning waste water as defined in claim 1, wherein said apparatus has a plurality of said continuous tubular biocontactors wound about said spaced longitudinal bars.
Claim 12
Dependent Claim
33 words
An apparatus for cleaning waste water as defined in claim 10, wherein the inlet ends of said tubular biocontactors are spaced from each other with respect to the circumference of said face plate.
Claim 13
Independent Claim
92 words
An apparatus for cleaning waste water in an enclosure or a confined space comprising: a rotatable shaft; a face plate mounted near each end of said shaft; a plurality of longitudinal bars spaced from each other and having their terminal portions adjacent to the periphery of said face plates; and at least one continuous tubular biocontactor wound at least partially around said longitudinal bars, said tubular biocontactors having an open inlet end and an open outlet end with both ends of the tubular biocontactor facing the direction of rotation of the shaft.
Claim 14
Independent Claim
92 words
An apparatus for cleaning waste water in an enclosure or a confined space comprising: a rotatable shaft; a face plate mounted near each end of said shaft; a plurality of longitudinal bars spaced from each other and having their terminal portions adjacent to the periphery of said face plates; and at least one continuous tubular biocontactor wound at least partially around said longitudinal bars, said tubular biocontactors having an open inlet end and an open outlet end with both ends of the tubular biocontactor facing the direction of rotation of the shaft.
Claim 15
Dependent Claim
48 words
An apparatus for cleaning waste water as defined in claim 12, wherein a portion of said continuous tubular biocontactor is folded upon itself around said inlet end of said tubular biocontactor, such that said outlet end of said tubular biocontactor faces the direction of rotation of said shaft.
Claim 16
Dependent Claim
30 words
An apparatus for cleaning waste water as defined in claim 12, wherein at least a part of said tubular biocontactor extends in an axial direction with respect to the shaft.
Claim 17
Dependent Claim
35 words
An apparatus for cleaning waste water as defined in claim 14, wherein said part of said tubular biocontactor extending in an axial direction with respect to the shaft extends to substantially the opposite face plate.
Claim 18
Dependent Claim
45 words
An apparatus for cleaning waste water as defined in claim 14, wherein the inlet end of said tubular biocontactor is located adjacent one of said face plates and the outlet end of said tubular biocontactor is located adjacent to the other of said face plates.
