Definitions
- the present invention belongs to the field of water treatment systems or devices, and more specifically to an apparatus for cleaning water that has suspended particles.
- the main object of the present invention is a tank for the separation of suspended particles from seawater or sewage, using saturated water and seawater, both being mixed inside a nozzle.
- Coagulation-flocculation is part of the process of water purification of surface water and the treatment of domestic, industrial and mining waters. These coagulation-flocculation processes facilitate the removal of suspended substances and colloidal particles. Coagulation is the destabilization of the colloidal particles caused by the addition of a chemical reagent called coagulant which, neutralizing its electrostatic charges, causes the particles to bind together. Likewise, flocculation is the agglomeration of destabilized particles in microflocules and then in larger flocs that tend to deposit in the bottom of the containers constructed for this purpose, called sedimentators.
- the factors that can promote coagulation and flocculation are the gradient of speed, time and pH. Time and the velocity gradient are important in increasing the probability that the particles will bind, and an adequate level of pH, for a given water, allows to register a good coagulation - flocculation in the shortest time.
- the particle separating tank comprises a container intended to accommodate seawater or wastewater, a sand filter located in the lower part of the container, and a nozzle located above the sand filter, which drives a flow towards the outer surface of the tank .
- This flow is formed by the mixture of water saturated with air and sea water that has been subjected to a coagulation-flocculation process, said mixture being made inside the nozzle. Both types of water are introduced into the nozzle by means of pipes.
- microbubbles of varying size depending on the pressure and the flow rate. These microbubbles drag the flocs and make them rise towards the upper part of the tank, where they accumulate forming a layer of mud that is collected and removed periodically.
- the air from the microbubbles escapes upon contact with the atmosphere, while the water already clean and free of particles is extracted through the sand filter located in the base of the container.
- the particle separating tank object of the invention comprises a lid located between the nozzle and the outer surface of the container, whose purpose is to increase the residence time of the microbubbles inside the tank, thus increasing the contact area between microbubbles and flocs. , and therefore, their separation.
- Bliss lid can be of variable size and dimension, preferably being circular, flat and narrow.
- the nozzle is housed in the center of the base of the container and has a truncated conical configuration, being wider at its base and narrowing at its upper end.
- said nozzle has a concentric inner lid and presents at its perimeter base a vertical section that is inserted in the lower surface of the container, and through which the introduction pipes of the water saturated with air and seawater circulate.
- seawater entering the tank may previously undergo a coagulation-flocculation process, in which the appropriate chemical reagents (for example iron or aluminum trichloride, subsequent water pH correction) are added to obtain Optimal coagulation
- Figure 1. Shows a sectioned general view of the particle separator tank object of the invention.
- Figure 2. Shows a sectional view of the nozzle in which the pipes that introduce the saturated water of air and the sea water are appreciated.
- Figure 3. Shows a plan view of the nozzle in which the arrangement of the aforementioned pipes is appreciated.
- the particle separator tank (10) comprises a container (1), a sand filter (2) located at the base of the container (1), and a nozzle (3) located above the sand filter (2) that drives a flow (4) towards the outer surface of the tank (10), said flow (4) being formed by the mixture of water saturated with air and sea water that It has been able to undergo a coagulation-flocculation process, said mixture being made inside the nozzle (3) and both types of water being introduced into the nozzle (3) by means of pipes (5).
- the water saturated with air creates microbubbles (6), of varying size depending on the pressure and the flow rate (4).
- microbubbles (6) drag the flocs and make them rise towards the upper part of the tank (10), where they accumulate forming a layer of mud (7) that is collected and removed periodically.
- the air from the microbubbles (6) escapes upon contact with the atmosphere, while the water already clean and free of particles is extracted through the sand filter (2) located in the base of the container (1).
- the particle separator tank (10) additionally comprises a lid (8), represented in Figure 1, of circular, flat and narrow configuration, which is preferably located in the central axis of the container (1), between the nozzle (3 ) and the outer surface, whose purpose is to increase the residence time of the microbubbles (6) inside the tank (10), thus increasing the contact area between microbubbles (6) and flocs, and therefore, their detection, separation and subsequent removal in the sludge layer (7).
- a lid (8) represented in Figure 1, of circular, flat and narrow configuration, which is preferably located in the central axis of the container (1), between the nozzle (3 ) and the outer surface, whose purpose is to increase the residence time of the microbubbles (6) inside the tank (10), thus increasing the contact area between microbubbles (6) and flocs, and therefore, their detection, separation and subsequent removal in the sludge layer (7).
- the nozzle (3) shown in Figures 2 and 3, is housed in the center of the base of the container (1) and has a truncated conical configuration, being wider at its base and narrowing at its upper end.
- Said nozzle (3) has a concentric inner cover (9) and a diameter slightly smaller than that of the base of the nozzle (3).
- a vertical section (3a) represented in Figure 2, which is inserted in the lower surface of the container (1), and through which the pipes (5) for introducing the water saturated with air and seawater.
