摘要： The centrifugal liquid pump is of the rotary discs types and has an integrated gas injector of very single yet efficient structure. This pump has a casing defining an inner, substantially cylindrical chamber with an axial liquid inlet and a tangential liquid outlet. A rotary impeller is rotatably mounted within the chamber. This impeller has first and second spaced apart discs which are rigidly interconnected at such a distance away from each other as to extend close to the opposite walls of the chamber. The first disc that extends close to the wall into which the liquid inlet opens has a central opening of the same diameter as the liquid inlet to allow the liquid injected through the inlet to enter within the chamber in between the discs. The second disc has a plurality of spaced apart openings located at a constant radius, which is inferior to the radius of the discs. A coaxial power shaft is connected to the impeller so as to rotate it in a given direction. This shaft extends out of the chamber in a direction opposite to the liquid inlet. A gas feed pipe is in open communication with the chamber. This gas feed pipe is connected to a hole made in the casing. This hole is located in the second opposite wall of the chamber at a radial distance substantially equal to the above mentioned constant radius. In use, the pressurized gas fed through the hole made in second opposite wall of the casing passes through the openings made in the second disc and enters into the chamber. The gas is then disolved in the liquid while the same moves between the discs toward the outlet of the pump.

摘要： Disclosed is a clarifier for use in treating a liquid containing non-soluble particles in suspension in order to separate these particles from the liquid. It comprises a tank, a liquid supply duct opening into the bottom portion of the tank and an injector for injecting a gas under pressure into at least part of liquid supplied to the supply duct in order to saturate this liquid with said gas and thus to generate gas bubbles as the saturated liquid is subject to depressurization within the tank. The gas bubbles that are so-generated adhere to the particles in suspension in the liquid and lift them up to form a floating layer of sludge in the top portion of the tank. A scraper is provided in the top portion of the tank for skimming off the layer of sludge while it is formed. A plurality of plates extend at an angle within the tank above the supply duct. These plates define a set of upwardly inclined channels each having an upper end that is opened and through which the liquid fed into the tank may enter the channel. A liquid outlet mounted within the lower end of each channel to collect and remove from the tank the liquid that has been treated within the same. Thanks to its shape and structure, this clarifier occupies a surface area on the ground that is 50% or less smaller than any known clarifier of the same capacity. Its structure also permits to maintain much more microbubbles of requested size for a same amount of injected air in order to increase the probability of contact between the particles and the air bubbles.

摘要： A floatation cell for treating wastewater in order to remove solid in suspension in the form of a floating sludge. This cell has a container which is rectangular in shape. A feed compartment in which the wastewater is fed, is located at one end of the compartment. A chute through which the floating sludge is collected and evacuated, is located at the other end of the container. The feed compartment has an outlet defined by a baffle that extends at a such height with respect to the top surface of the wastewater, as to generate a draining flow which directs the floating sludge towards the chute. The container also comprises scrappers mounted on its internal walls so as to be movable in an alternative, back and forth movement in order to avoid that the sludge accumulates on the walls and holds up the flow towards the chute. This system of evacuating the sludge is much simpler than the existing systems and the maintenance of the floatation cell is much easier to carry out.

摘要： Disclosed is a centrifugal liquid pump, preferably of the rotary disc type, which incorporates a gas injection assembly of very simple yet efficient structure, whereby up to 15% per volume of a gas such as air, may be mixed with the pumped liquid. The gas injection is achieved with a gas feed pipe that enters the pump through its axial inlet and with a plurality of gas injector pipes that projects from the gas feed pipe radially within the impeller.
