Resumo: In this work polymeric membranes were produced seeking the drinkableness of waters contaminated by the Escherichia coli bacteria removal. This bacterium was chosen because it is commonly found in polluted water and its control indicated by the Ministry of Health. The process for preparing the membranes was the Phase Inversion and the membranes were prepared from a polymeric solution using either the polysulfone (PSF) or poly(vililidene fluoride) (PVDF) polymers and as solvent N,N-dimethylformamide, in accordance with a factorial planning 23. Samples of deionized water were contaminated with bacterial mass (E.coli) around 107-108 CFU (colony unit formation) for ml, being this quite high bacterial load and of very difficult removal. The results show an E.coli removal above 95%, with a permeated flux around 300 kg/h.m2

A escolha desta bactéria deveu-se por esta ser comumente encontrada em águas contaminadas e seu controle indicado pelo Ministério de Saúde. O processo para o preparo das membranas foi a Inversão de Fase e as membranas foram preparadas a partir de uma solução polimérica usando ora o polímero polisulfona (PSF) ora o fluoreto de polivililideno (PVDF) e como solvente, o N,N-dimetilformamida, seguindo um planejamento fatorial 23. Amostras de água deionizada foram contaminadas com uma massa bacteriana (E.coli) em torno de 107-108 UFC (unidade formadora de colônias) por ml, sendo esta uma carga bacteriana bastante elevada e de difícil remoção. Os resultados mostram uma remoção da E.coli acima de 95%, com fluxos permeados em torno de 300 kg/h.m2Universidade Estadual De Maringá2008-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/149310.4025/actascitechnol.v26i2.1493Acta Scientiarum.
