Abstract

La presente invenzione riguarda un reattore per la rimozione di impurità da un liquido, in particolare per la disinchiostrazione, comprendente un serbatoio (1) entro il quale entra (2-3) il liquido da depurare insieme a gas o aria; uno scarico dell'accettato depurato attraverso una uscita (7) di detto serbatoio (1); delle entrate (8-11, 9-12, 10-13) a diverse altezze del serbatoio (1) collegate con lo scarico (7) del liquido depurato insieme all'entrata di gas o aria; un albero rotante (18) all'interno del serbatoio (1) portante delle pale (20, 21, 22, 23) in corrispondenza di diverse altezze del serbatoio entro le quali entra il liquido insieme a gas o aria; le pale (20, 21, 22, 23) aventi altezze man mano maggiori andando verso la parte inferiore del serbatoio (1). L'invenzione si riferisce anche al metodo realizzato con il reattore di cui sopra.
