Definitions
- the invention relates to a process for the continuous purification of water, which comprises a series of purifying devices placed in series and under pressure in a closed circuit, of a reduced volume, making it possible to obtain, in a very short time, only 2 to 3 hours, leaving water having characteristics, physical, chemical and biological, conforming, or even superior in quality, to those currently required by French legislation for discharges of urban wastewater into rivers.
- This tank is at a pressure of 1 to 4 bars. It is preferably cylindrical, accessible because it has a removable cover (4) Fig 1, of rounded shape.
- the inlet of the water to be treated is located on the upper part of the tank, it is fitted with a non-return valve (10) Fig 1, in order to avoid backflow of the water and to be able to maintain a stable pressure and adequate.
- This tank has an air inlet (6) Fig 1, which is under pressure. It is in the form of a stainless steel tube, with a length equal to the diameter of the tank, perforated with multiple holes.
- this tank is rounded (5) Fig 1 and includes the waste water outlet (9) Fig 1.
- the tank rests on a frame (8) Fig 1.
- the outlet flow rate of this tank is regulated by the valve retainer (10) Fig 1, which maintains the pressure
- This tank will vary depending on the flow of water to be treated. For example, for a treatment of 50m3 / hour, it will have a capacity of the order of 3m3.
- the air injected at level (6) Fig 1, using a compressor (11) Fig 5, should have a pressure of the order of 10 bars so that the air + water mixture contained in the tank is at a resulting pressure of 1 to 4 bars, a pressure which can be varied substantially depending on the degree of purification desired during the treatment.
- This additional addition of hydrogen peroxide will be made in order to obtain an even more thorough purification of the water and allow, if necessary, a denitrification until obtaining nitrate contents in accordance with the regulations in force at present.
- the passage of the waters to be treated in this first tank represents a first stage in this treatment process, which takes place continuously and in a closed circuit.
- this water will feed, still under pressure, a second tank called "accelerated settling” (20) Fig 5.
- the supply will be by a side inlet of the water (21) Fig 2 and Fig 3, so that the aerated liquid arrives in this tank in a rotating jet.
- This tank will have a capacity similar to the first tank, ie for the aforementioned example, with a volume of the order of 3m3. It will preferably have the cylindro-conical shape. It is composed of a perforated rotary drum (22) Fig 2 and Fig 3, rotating at low speed, continuously. Inside this drum is welded an archimedean screw (23) Fig 2 which allows the water to circulate downwards. This rotating drum has the effect of helping the particles in suspension to descend more quickly towards the bottom of the funnel-shaped tank (24) Fig 2 where the sludge outlet (25) is located Fig 2. These sludges are maintained at this level by an adjustable pressure check valve and will be sucked in intermittently using a pump.
- this second tank At the upper part of this second tank, is attached to the large rotary drum, a second drum (26) Fig 2, perforated with multiple holes (27) Fig 2, allowing a selection of the heavy particles in suspension and driving them back to the 'outside.
- An arrival (35) Fig 2 is provided for additives.
- This settling of water can be accelerated and perfected by combining the arrival of water with an inlet (28) Fig 2 of milk of lime or of metallic salts, injected under pressure.
- a variable speed motor (29) Fig 2 will allow the speed of rotation of the two drums to be adjusted.
- This basin (31) Fig 5 called “final decantation”, is provided with a surface scraper ("é) Fig 5 to remove the last floating suspended particles, it has multiple weirs (conventional device).
- REPLACEMENT SHEET takes place in an expansion chamber, its purpose is to participate in the release of gaseous substances and in the destruction of part of the microbial flora which will not resist this sudden difference in pressure.
- the whole of this new water purifier system can operate in full automaticity. It is interesting for treatment stations with a capacity of 20 to 500 m3Lhour, or even more.
