Abstract
Abstract A rotary multitube biocontactor has a plurality of tubes of a predetermined length and diameter. The tubes are bundled in a pillar like form and are connected with each other and with an axle at the sectional center thereof by means of welding or the like. The plurality of tubes are at angles to the axle, the axle being mounted in bearings provided on a trough at the top of two sidewalls thereof so as to enable the axle to be located close to the surface of water contained in the trough. The axle is rotated by a motor connected thereto thereby rotating the multitube biocontactor so that the tubes move in and out of the water contained in the trough.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
A rotary multi-tube bicontactor apparatus for treating fluids comprising: an open trough for containing the fluid to be treated; a rotary rod attached across said trough above the surface of the fluid therein; rotating means attached to said rotary rod for rotating said rotary rod; and a plurality of tube means longitudinally askew to and surrounding said rotary rod, longitudinally askew to each other, partially submerged in the fluid in said trough, and operatively connected to said rotary rod for moving in and out of the fluid in said trough as said rod rotates, each tube means comprised of: a plurality of tubes, and binding means surrounding said tubes for holding said tubes together, whereby a tube bundle is formed.
Claim 2
Dependent Claim
120 words
A rotary multi-tube bicontactor apparatus for treating fluids comprising: an open trough for containing the fluid to be treated; a rotary rod attached across said trough above the surface of the fluid therein; rotating means attached to said rotary rod for rotating said rotary rod; and a plurality of tube means longitudinally askew to and surrounding said rotary rod, longitudinally askew to each other, partially submerged in the fluid in said trough, and operatively connected to said rotary rod for moving in and out of the fluid in said trough as said rod rotates, each tube means comprised of: a plurality of tubes, and binding means surrounding said tubes for holding said tubes together, whereby a tube bundle is formed.
Claim 3
Dependent Claim
22 words
An apparatus as claimed in claim 1, wherein each tube is comprised of a network of wires formed in a tubular shape.
Claim 4
Dependent Claim
43 words
An apparatus as claimed in claim 1, wherein each tube is from 2cm to 7cm in diameter and is comprised of a network of wires 2mm to 3mm in thickness arranged in a longitudinal tubular shape with meshes ranging from 3mm to 15mm.
Claim 5
Dependent Claim
24 words
An apparatus as claimed in claim 1, wherein said binding means is comprised of at least one ring surrounding and holding said tubes together.
Claim 6
Dependent Claim
25 words
An apparatus as claimed in claim 1, wherein said binding means is comprised of a hollow, open-eyed cylindrical container surrounding and containing said tubes therein.
Claim 7
Dependent Claim
17 words
An apparatus as claimed in claim 1, wherein said tubes are bound together with vacant spaces thereinbetween.
Claim 8
Dependent Claim
68 words
An apparatus as claimed in claim 1, further comprising: fan means directed toward said tube means above the surface of the fluid in said trough for forcing air across and through said tube means, whereby the fluid films picked up by the rotation of the tube means through the trough partially vaporize and radiate heat therefrom as a result of the air passing thereover from said fan means.
Claim 9
Dependent Claim
102 words
A rotary multi-tube biocontactor apparatus for treating fluids comprising: a rotary rod above the surface of the fluid to be treated; rotating means attached to said rotary rod for rotating said rotary rod; and a plurality of tube means longitudinally askew to and surrounding said rotary rod, longitudinally askew to each other, partially submerged in said fluid, and operatively connected to said rotary rod for moving in and out of said fluid as said rod rotates, each tube means comprised of: a plurality of tubes, and binding means surrounding said tubes for holding said tubes together, whereby a tube bundle is formed.
Claim 10
Dependent Claim
102 words
A rotary multi-tube biocontactor apparatus for treating fluids comprising: a rotary rod above the surface of the fluid to be treated; rotating means attached to said rotary rod for rotating said rotary rod; and a plurality of tube means longitudinally askew to and surrounding said rotary rod, longitudinally askew to each other, partially submerged in said fluid, and operatively connected to said rotary rod for moving in and out of said fluid as said rod rotates, each tube means comprised of: a plurality of tubes, and binding means surrounding said tubes for holding said tubes together, whereby a tube bundle is formed.
