Abstract
L'apparecchiatura (10) per il trattamento delle acque comprende una struttura galleggiante (12) che supporta, immersa nell'acqua a profondità regolabile ed orientamento nel piano verticale pure regolabile, un'unità operativa (30) comprendente un'elica (50) azionata da motore sommergibile, ed una camera di decompressione (38) avente almeno un'entrata (42) per l'aria in comunicazione con una tubazione di aspirazione (24, 26) che sbocca (44) al di sopra del pelo libero dell'acqua, la camera di decompressione avendo anche un'uscita (46) per l'aria. L'elica (50) è completamente esterna alla camera di decompressione (38); il mozzo (48) dell'elica (50) è cavo e comunica, oltre che con l'esterno, anche con l'uscita (46) della camera di decompressione (38).Un convenzionale dispositivo di tenuta a rotazione assicura la tenuta tra mozzo (48) e parte fissa dell'unità operativa (30).
