Each day the water scarcity at the global level is worrying and the industries are faced with the enormous challenge to prevent contamination of existing resources. Separation processes with polymer membranes have been successfully used in separating small quantities of oil in water. The synthesis conditions of UHMWPE tubular membranes, as well as its internal coating of LDPE film with the addition of organophilic clay were evaluated for promoting the generation of micropores, which would allow a more efficient filtration. Through the techniques of flow analysis, it was found that membranes with clay were more effective for filtration. The quantification of the concentration of oil showed the benefits of the application of this technique, resulting in extremely low levels of oil in water. |
