Abstract

Metodo di riutilizzo acque di lavaggio nel campo fotografico, in cui le acque di lavaggio provenienti dalle sviluppatrici vengono sottoposte ad un processo di filtrazione, ad una fase di innocuizzazione ai fini fotografici dei sali presenti nelle acque di lavaggio, ad una fase di innocuizzazione, la fase di innocuizzazione comportante il ricircolo di almeno una frazione percentuale dell'acqua di lavaggio e la trasformazione delle sostanze presenti nelle acque di lavaggio in composti compatibili con il materiale fotosensibile.Apparecchiatura idonea a concretizzare il metodo di cui sopra, comprendente un circuito di ricircolo (23, 28, 25) e mezzi dosatori (30) asserviti al lettore superficie materiale sensibile (32), detti mezzi dosatori (30) essendo associati ai rispettivi serbatoi (26, 27) della prima e seconda soluzioni rigeneratrici (A e B).
