Abstract
Abstract A combined toilet and sewage treatment apparatus comprising a bowl provided with a drainage aperture; a primary treatment chamber providing a first electrolyte reservoir, a secondary treatment chamber providing a second electrolyte reservoir; means for circulating electrolyte between said second reservoir and said bowl to flush said bowl, the electrolyte during circulation passing from said bowl through said drainage aperture to said first reservoir and from said first reservoir to said second reservoir when its level in said first reservoir reaches a predetermined level; and a pair of electrodes positioned in each of said first and second reservoirs so that when current is supplied to said electrodes, electrolysis of sewage in the electrolyte in both said reservoirs occurs.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
A combined toilet and sewage treatment apparatus comprising a bowl provided with a drainage aperture; a primary treatment chamber providing a first electrolyte reservoir, a secondary treatment chamber providing a second electrolyte reservoir; means for circulating electrolyte between said second reservoir and said bowl to flush said bowl, the electrolyte during circulation passing from said bowl through said drainage aperture to said first reservoir and from said first reservoir to said second reservoir when its level in said first reservoir reaches a predetermined level; and a pair of electrodes positioned in each of said first and second reservoirs so that when current is supplied to said electrodes, electrolysis of sewqge in the electrolyte in both said reservoirs occurs.
Claim 2
Dependent Claim
118 words
A combined toilet and sewage treatment apparatus comprising a bowl provided with a drainage aperture; a primary treatment chamber providing a first electrolyte reservoir, a secondary treatment chamber providing a second electrolyte reservoir; means for circulating electrolyte between said second reservoir and said bowl to flush said bowl, the electrolyte during circulation passing from said bowl through said drainage aperture to said first reservoir and from said first reservoir to said second reservoir when its level in said first reservoir reaches a predetermined level; and a pair of electrodes positioned in each of said first and second reservoirs so that when current is supplied to said electrodes, electrolysis of sewqge in the electrolyte in both said reservoirs occurs.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 further including means for evaporating fluid from the electrolytes and discharging the evaporated fluid to the exterior of the apparatus.
Claim 4
Dependent Claim
71 words
The apparatus of claim 1, wherein an ion permeable barrier is provided in said seond treatment chamber, said barrier being positioned between the two electrodes in said chamber and providing two discrete chambers between which ions can pass but which prevents the passage of visible electrolyte born paritcles, said ion permeable barrier extending to a height which is at least above the normal level of electrolyte in said second treatment chamber.
Claim 5
Dependent Claim
49 words
The apparatus of claim 1, wherein at least one of the electrodes in the secondary treatment chamber is plate-shaped and is located in a position parallel to a plane defined by the surface of the electrolyte in the secondary treatment chamber when such electrolyte is in its normal position.
Claim 6
Dependent Claim
33 words
The apparatus of claim 1, wherein a macerator is provided with said macerator being positioned in the apparatus so as to macerate all solids flowing from said bowl to said primary treatment chamber.
Claim 7
Dependent Claim
26 words
The apparatus of claim 1, wherein an ultraviolet light source is provided, it being positioned so as to direct ultraviolet rays into said secondary treatment chamber.
Claim 8
Dependent Claim
15 words
The apparatus according to claim 1, wherein all of said electrodes are of plate shape.
