ABSTRACT:
The floating apparatus comprises a cyclone carrying a normally submerged forming with the body of the cyclone a water compartment containing the cyclone inlet orifice. The sill of the dam is situated below but close to the free surface of the body of water from which the pollutant is to be removed and such sill is formed to create a continuous flow of water and pollutant into the compartment to form therein a level of the mixture lower than that of the free surface of the body of water. The dam has a height enabling the level of the water in the compartment to be maintained constantly higher than the inlet orifice of the cyclone. Suction means are connected to the lower outlet for filling the cyclone up to its ceiling with the liquid mixture from the compartment for producing in such mixture a cyclonic rotation capable of separating the water and pollutant by centrifugation and concentrating the pollutant in an axial central zone of the cyclone, and for removing the water freed from the pollutant through the lower outlet of the cyclone. Another suction means removes the separated concentrated pollutant through the ceiling of the cyclone. Means are provided to adjust the inlet flow of the cyclone so as to maintain the level of the mixture in the compartment at a constant height.
