Abstract: A device designed for being adapted to surround a duct formed with one or several orifices operable for feeding a fluid to an apparatus, such as a reactor, used for the treatment of liquids, notably water, and including a resiliently deformable membrane, also formed with one or several orifices communicating with that or those of the fluid feeding duct, characterized in that it is made of two half shells threaded and clamped onto the fluid inlet duct, one of which having a housing for the resiliently deformable membrane and an orifice for the distribution of the fluid to the apparatus.

Abstract: This invention provides a method and an apparatus for effecting counter-current mass exchange between two non-miscible phases A and B, for example a liquid phase A and a liquid or solid phase B, circulating in opposite directions from one end to an opposite end of a vertical tower comprising a plurality of superposed chambers in which the first phase A is caused to circulate continuously and the second phase B is caused to circulate discontinuously. One chamber is empty and is adapted to receive the phase B contained in the next chamber thereabove, the two chambers being isolated from any supply of phases A and B. A small fraction of the liquid phase A is diverted for directing continuously this phase to the other chambers of the tower, the thus diverted fraction being introduced into the next chamber above the empty chamber for carrying away the phase B contained in the lower empty chamber, this diverted fraction being reintroduced into the circuit.

Abstract: Improved fluidizing apparatus adapted to separate continuously ion exchange resins having different densities in order to perform their selective classification according to suitable granulometric distributions. The apparatus comprises a first separation chamber and in the lower portion of this first separation chamber a second chamber coaxially thereto having a gradually increasing cross-section from the bottom to the top.

Abstract: A flotation apparatus comprises essentially a parallelepipedic tank disposed horizontally and provided along its major axis with open-top, potlike injectors for the liquid to be treated with another liquid saturated with gas under pressure. The liquid to be treated is delivered through the bottom and preferably centrally of each injector, and the treatment liquid is supplied through a lateral, eccentric but non-tangential pipe. Siphonal means are provided along the major side walls of the tank and are adapted, in conjunction with the injectors, to create outward and downward fluid flow passing under the siphonal means, other means being provided for removing the top sludge from one end of the tank.
