Abstract
Abstract A filtering system for use with fish-containing ponds and bodies of water is disclosed. More particularly, the filtering system includes chambers for harboring micro-organisms which clean organic waste from the water flowing therethrough from the pond. The chambers include by-pass conduits so that a given chamber may be taken out of service for cleaning without interrupting the flow of water through the rest of the system. Further, movable walls are provided so that several chambers contained in a single structure may be varied in number and in size according to a pond's requirements. Also included is an air manifold for use in supplying air to the micro-organisms.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
A filtering system for filtering the water in a man-made pond of the type containing fish, said system comprising: means for defining a plurality of chambers with at least one of said chambers having micro-organisms for scavenging organic waste matter from the water entering said chambers from the pond, said means being a single structure having end walls, side walls, a floor and including intermediate walls between and defining adjacent chambers, said intermediate walls including hollow enclosures devoid of water; inlet means attached to and extending between said single structure and the pond for directing water from the pond to said single structure; outlet means for directing water from said single structure to the pond; first conduit means fluidly connecting each of said plurality of chambers, said first conduit means being disposed in each of said hollow enclosures; and second conduit means for being selectively integrated into said first conduit means whereby the flow of water through the system may bypass at least one chamber.
Claim 2
Dependent Claim
165 words
A filtering system for filtering the water in a man-made pond of the type containing fish, said system comprising: means for defining a plurality of chambers with at least one of said chambers having micro-organisms for scavenging organic waste matter from the water entering said chambers from the pond, said means being a single structure having end walls, side walls, a floor and including intermediate walls between and defining adjacent chambers, said intermediate walls including hollow enclosures devoid of water; inlet means attached to and extending between said single structure and the pond for directing water from the pond to said single structure; outlet means for directing water from said single structure to the pond; first conduit means fluidly connecting each of said plurality of chambers, said first conduit means being disposed in each of said hollow enclosures; and second conduit means for being selectively integrated into said first conduit means whereby the flow of water through the system may bypass at least one chamber.
Claim 3
Dependent Claim
21 words
The filtering system of claim 1 further including gate means to regulate the flow of water into each of said chambers.
Claim 4
Dependent Claim
84 words
The filtering system according to claim 1 further including an air manifold for use in said chambers, said manifold comprising; a hollow center section having a nipple for receiving an air supply tube; a plurality of hollow arms, attached to said center section and extending outwardly therefrom, said arms being provided with air release means for permitting air to leave said arms and bubble up through the media; and support means for supporting said arms and center section off a floor of the chamber.
Claim 5
Dependent Claim
18 words
The air manifold of claim 3 wherein said air release means include air stones attached to said arms.
Claim 6
Dependent Claim
19 words
The air manifold of claim 3 wherein said air release means include perforations along the length of said arms.
Claim 7
Dependent Claim
22 words
The air manifold of claim 3 wherein said arms include free ends which are positioned at an angle relative to said arms.
Claim 8
Dependent Claim
160 words
A filtering system for filtering the water in a man-made pond of the type containing fish, said system comprising: means for defining a plurality of chambers including means for harboring micro-organisms for scavenging organic waste matter from the water entering said plurality of chambers from the pond, said plurality of chambers being positioned in and part of a single structure having end walls, side walls and a floor, said chamber defining means also including intermediate walls between and common to adjacent chambers, said intermediate walls including hollow enclosures devoid of water; inlet means for directing water from the pond to said single structure; outlet means for directing water from said single structure to the pond; first conduit means fluidly connecting each of said plurality of chambers, said first conduit means being disposed in each of said hollow enclosures; and means for bypassing at least one chamber whereby the flow of water through said system may bypass at least one chamber.
Claim 9
Dependent Claim
160 words
A filtering system for filtering the water in a man-made pond of the type containing fish, said system comprising: means for defining a plurality of chambers including means for harboring micro-organisms for scavenging organic waste matter from the water entering said plurality of chambers from the pond, said plurality of chambers being positioned in and part of a single structure having end walls, side walls and a floor, said chamber defining means also including intermediate walls between and common to adjacent chambers, said intermediate walls including hollow enclosures devoid of water; inlet means for directing water from the pond to said single structure; outlet means for directing water from said single structure to the pond; first conduit means fluidly connecting each of said plurality of chambers, said first conduit means being disposed in each of said hollow enclosures; and means for bypassing at least one chamber whereby the flow of water through said system may bypass at least one chamber.
Claim 10
Dependent Claim
42 words
The filtering system according to claim 7 wherein said intermediate walls include a vertical planar central portion and dual axial angular extensions at each end with said hollow enclosures being defined by said dual axial angular extensions cooperating with said side walls.
Claim 11
Dependent Claim
183 words
The filtering system for filtering water from a body of water of the type containing fish, said system comprising: a vessel containing a plurality of spaced apart walls defining first and second chambers, said walls including side walls, end walls, a floor and an intermediate wall between and common to said chambers, said intermediate wall having at least one hollow enclosure devoid of water; filtering means in a first chamber for filtering particulate matter from water entering said vessel from the body of water; biological support means in a second chamber for supporting micro-organisms for scavenging organic waste matter from water entering said second chamber from said first chamber; inlet means for directing water from the body of water to said first chamber; outlet means for directing water to the body of water from said second chamber; first conduit means fluidly connecting said first and second chambers and disposed in said at least one hollow enclosure; and second conduit means integrated into said first conduit means for diverting the water to permit the selective bypassing of either the first or the second chamber.
