Abstract
An apparatus for the clarification of liquids, such as notably water, fruit juices, musts such as grape musts, including an enclosure in which is brought the liquid to be clarified after a pretreatment operation, such as screening, as well as a flotation equipment, fed by a transfer pump with liquid pressurized and relieved of the pressure prior to its introducting in the flotation equipment, from which the clarified liquid is introduced in a filtration system. The apparatus includes the features that the flotation equipment is placed above the assembly used for the pretreatment of the liquid so as to obtain a sufficient load for bringing about a hydraulic balance of the various constituents of the apparatus, in order that it can operate with a small load available upstream and allow a possible recycling, by simple gravity, of the floating particles collected at the surface of the flotation equipment to any point of the pretreatment.
