Abstract

La presente invenzione ha per oggetto una apparecchiatura per recuperare sostanze fluide galleggianti sulla superficie dell'acqua, composta da una pluralità di dischi disposti su un asse orizzontale, parzialmente immersi nell'acqua e rotanti con velocità diverse ed in particolare alternativamente in senso orario ed antiorario.I dischi semisommersi, sfruttando il principio dell'adesione maggiore delle sostanze oleose rispetto all'acqua, le raccolgono mentre le stesse vengono poi distaccate da sistemi raschianti e convogliate ad un vano di contenimento.
