Abstract
Abstract The present invention relates to a water purifying device for treating the waste and cess water from an individual or collective house. Such a water purifying device comprises a tight tank, a feeding pipe and an exhaust pipe extending inside the tank in order to provide siphons, an air compressor supplying a control valve is provided which supplies air alternately to a pipe submerged in the liquid in the tank or to the air space above the tank. According to one mode of operation, the tank is maintained under a variable pressure always higher than the atmospheric pressure during the treatment operation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
195 words
A water purifying device comprising a single tank defining a single chamber, a water feeding pipe extending into said chamber and having an outlet disposed in said chamber at a selected level, a water exhaust pipe extending into said chamber and having an outlet located in said chamber at a level above said selected level, the level at which said water exhaust pipe extends out of said chamber being lower than the level at which said water feeding pipe extends into said chamber, said tank having an upper portion and means for supplying gas under pressure at said upper portion, a stationary gas dispersing means extending into said tank to the lower part of said chamber, gas flow means located at the upper part of said chamber, and control valve means connected to said gas supplying means, said control valve means being movable, at least, between a first position, wherein gas under pressure is supplied to said stationary gas dispersing means and said gas flow means is connected to the atmosphere, and a second position, wherein said gas supplying means is connected to said gas flow means and said stationary gas dispersing means is closed.
Claim 2
Dependent Claim
195 words
A water purifying device comprising a single tank defining a single chamber, a water feeding pipe extending into said chamber and having an outlet disposed in said chamber at a selected level, a water exhaust pipe extending into said chamber and having an outlet located in said chamber at a level above said selected level, the level at which said water exhaust pipe extends out of said chamber being lower than the level at which said water feeding pipe extends into said chamber, said tank having an upper portion and means for supplying gas under pressure at said upper portion, a stationary gas dispersing means extending into said tank to the lower part of said chamber, gas flow means located at the upper part of said chamber, and control valve means connected to said gas supplying means, said control valve means being movable, at least, between a first position, wherein gas under pressure is supplied to said stationary gas dispersing means and said gas flow means is connected to the atmosphere, and a second position, wherein said gas supplying means is connected to said gas flow means and said stationary gas dispersing means is closed.
Claim 3
Dependent Claim
115 words
A water purifying device comprising a single tank defining a single chamber, a waste water feeding pipe and a water exhaust pipe extending into said tank, said water exhaust pipe having lower and upper ends which are at respectively higher and lower levels than the ends of said water feeding pipe, said device further comprising an air compressor and control valve means located in the upper part of said tank, said control valve means being movable from one position for supplying compressed air from said air compressor to a stationary gas dispersing means extending inside said tank, and to a second position wherein said compressed air is supplied to the upper part of said tank.
Claim 4
Dependent Claim
115 words
A water purifying device comprising a single tank defining a single chamber, a waste water feeding pipe and a water exhaust pipe extending into said tank, said water exhaust pipe having lower and upper ends which are at respectively higher and lower levels than the ends of said water feeding pipe, said device further comprising an air compressor and control valve means located in the upper part of said tank, said control valve means being movable from one position for supplying compressed air from said air compressor to a stationary gas dispersing means extending inside said tank, and to a second position wherein said compressed air is supplied to the upper part of said tank.
Claim 5
Dependent Claim
76 words
A water purifying device, according to claim 1, wherein said control valve means comprises a venting port connected with the upper part of the tank when said control valve is in a position where said auxiliary gas under pressure is connected to said gas dispersing means, said venting port being calibrated in relation with the flow of said auxiliary gas under pressure to maintain a slight excess of pressure in the tank during the venting operation.
Claim 6
Dependent Claim
47 words
A water purifying device, according to claim 1, wherein said gas dispersing means comprising a generally conical-shaped cupola, having the vertex at the top, set at the lower end of a substantially vertical tube, which is located inside the tank and connected to said control valve means.
Claim 7
Dependent Claim
23 words
A water purifying device, according to claim 2, wherein the walls of said exhaust pipe have an opening slightly above its lower end.
Claim 8
Dependent Claim
26 words
A water purifying device, according to claim 3, wherein said venting port of said control valve is connected to the upper part of said feeding pipe.
Claim 9
Dependent Claim
21 words
A water purifying device, according to claim 1, wherein said exhaust pipe comprises at its lower end a pervious synthetic diaphragm.
Claim 10
Dependent Claim
41 words
A water purifying device, according to claim 1, wherein said means for supplying gas under pressure is connected to said control valve means by means of a gas feeding pipe and said gas feeding pipe is provided with a non-return valve.
Claim 11
Dependent Claim
38 words
A water purifying device, according to claim 2, also comprising a heating means, so located to warm the gas introduced in the tank, and to maintain the tank at an appropriate temperature for ensuring a sufficient biological reaction.
