This thesis explores the application of Membrane BioReactor (MBR) technology as an advanced solution for upgrading wastewater treatment plants, with a specific focus on the design of a facility to treat the effluents from a biotechnology company based in Lodi, Italy. In a context increasingly marked by the need to minimize environmental impact and optimize space usage, MBR technology proves particularly effective due to its compact footprint, high purification efficiency, and reduced sludge production. The study covers the full design process of the plant, from wastewater characterization to the development of the biological treatment system, highlighting the technical decisions made and the advantages achieved in terms of effluent quality, operational flexibility, and cost containment. The plant is designed to meet the stringent discharge limits set by Italian legislation (D.Lgs. 152/2006) and aligns with the goals of the United Nations 2030 Agenda. Economic and environmental analyses confirm the long-term sustainability of the technological choice, offering concrete opportunities for the reuse of treated water in industrial and agricultural applications.
La presente tesi analizza l’applicazione della tecnologia MBR (Membrane Bio Reactor) come soluzione avanzata per il potenziamento degli impianti di depurazione, con particolare riferimento alla realizzazione di un impianto destinato al trattamento dei reflui prodotti da un’azienda biotecnologica lodigiana. In un contesto caratterizzato dalla crescente necessità di contenere l’impatto ambientale e ottimizzare gli spazi, la tecnologia MBR si dimostra particolarmente adatta grazie alla sua compattezza, efficienza depurativa e capacità di ridurre la produzione di fanghi. Il lavoro affronta il dimensionamento completo dell’impianto, dalla caratterizzazione dei reflui alla progettazione del processo biologico, evidenziando le scelte tecniche adottate e i vantaggi ottenibili in termini di qualità dell’effluente, flessibilità gestionale e contenimento dei costi operativi. L’impianto è progettato per garantire prestazioni elevate in conformità al D.Lgs. 152/2006 e in linea con gli obiettivi dell’Agenda ONU 2030. L’analisi economica e ambientale conferma la sostenibilità della scelta tecnologica, aprendo prospettive concrete per il riutilizzo delle acque trattate in ambiti industriali e agricoli.

The study covers the full design process of the plant, from wastewater characterization to the development of the biological treatment system, highlighting the technical decisions made and the advantages achieved in terms of effluent quality, operational flexibility, and cost containment. The plant is designed to meet the stringent discharge limits set by Italian legislation (D.Lgs. 152/2006) and aligns with the goals of the United Nations 2030 Agenda. Economic and environmental analyses confirm the long-term sustainability of the technological choice, offering concrete opportunities for the reuse of treated water in industrial and agricultural applications.| File | Dimensione | Formato | |
