Sistemas de tratamento de água utilizando processo de separação por membranas de ultrafiltração: estudo de caso

Abstract

In this case study, the separation process by ultrafiltration membranes was analyzed, which is a great alternative for the treatment of water from reservoirs which are degraded over time, which are mainly located in regions that have a high urban growth. With the possibility of obtaining water with better quality in treatment plants, since conventional water treatment systems have limitations to treat new by-products of pollution, such as endocrine disruptors. As a focus, the operational and material removal results of three pilot plants, developed in the Guarapiranga Reservoir, a degraded spring in the Metropolitan Region of São Paulo, were analyzed because these pilot plants are pioneer studies on the UF in Brazil. Project Prosab-04, PROSAB05 and the one developed by Oliveira were operated using only an ultrafiltration membrane in the pressure vessel and the results obtained by the authors were proof of how efficient the ultrafiltration membrane separation system and the potential for implementation in treatment plants that use the conventional treatment system. In addition to the excellent level of pollutant removal, this system still has a competitive cost compared to conventional and conventional systems that use activated carbon, but when making such comparisons, not only the cost, but also the efficiency must be considered, since, removes new pollutants present in the water source, in addition to needing a small space to implement the ultrafiltration system when compared to the conventional system.
