Abstract

Un procedimento in un dispositivo per il trattamento d'acqua sono atti ad eseguire un trattamento di rigenerazione dell'acqua fangosa una volta che sia stata impiegata in una operazione di scavo ad acqua per ridurre il suo peso specifico per il reimpiego nella operazione o lavoro di scavo ad acqua ed un trattamento di disidratazione di varie acquee di scarico come acqua fangosa dal lavoro di scavo ad acqua e acqua di scarico industriale per l'eliminazione o la discarica finale.Il trattamento di disidratazione include una fase di flocculazione per far flocculare fini particelle fangose, una fase di separazione di parte solida-parte liquida per separare il fiocco o materiale flocculato in una parte solida e in una parte liquida, una fase di scarico per scaricare la parte liquida attraverso una fase di filtrazione o depurazione dell'acqua, ed una fase di trattamento della parte solida per trattare la parte solida separata nella fase di separazione della parte solida-liquida, ed il trattamento di rigenerazione includendo una fase di separazione della parte solida-parte liquida per separare l'acqua fangosa in una parte solida ed una parte liquida in una fase di reimpiego per reimpiegare la parte liquida separata che è stata privata delle particelle fangose mediante la fase di separazione della parte solida-parte liquida, ed una fase di trattamento della parte solida per trattare la parte solida separata nella fase di separazione della parte solida-parte liquida.la fase di separazione della parte solida-parte liquida è realizzata mediante un separatore centrifugo il cui contenitore interno è costituito da una parete non perforata e da un fondo sagomato a ruota.
