Analiza delovanja membranskega sistema za pripravo vode

Trojar, Janez (author), Golobič, Iztok (mentor)

Za pripravo kakovostne tehnološke vode smo v diplomski nalogi izvedli načrtovanje ultrafiltracijskega sistema z vsemi ključnimi komponentami, katerega smo v želji po višji učinkovitosti nadgradili s konvencionalnim postopkom filtracije, sistemom za recikliranje pralne vode in z nadzornim sistemom za zajem podatkov ter podali stroškovno oceno načrtovanega sistema. Analizirali smo odzive ultrafiltracijskih sistemov na različne parametre vstopne vode, obdelali načine čiščenja ultrafiltracijskih membran ter podali vpliv na učinkovitost in obratovalno dobo. Na podlagi primerjave s starejšimi sistemi smo podali prednosti novejših ultrafiltracijskih sistemov in glede na ugotovitve podali smernice za vzdrževanje ultrafiltracijskih sistemov.

Abstract

This diploma thesis features the design of an ultrafiltration system, intended for the preparation of high-quality technological water, which is equipped with all the necessary key components, and has been upgraded with a conventional filtration process, a system for recycling backwashing water and a control system for data acquisition, in order to achieve higher efficiency and provide a cost estimation for the designed system. Furthermore, it includes an analysis of the responses of ultrafiltration systems to various feed water parameters, a revision of ultrafiltration membranes cleaning methods and their impact on the efficiency and operating life of these systems, a presentation of the advantages of newer ultrafiltration systems in comparison with previous ones, and guidelines for the maintenance of ultrafiltration systems, based on the findings, featured in this thesis.
