Applications of the Ultrafiltration Membranes in the Industrial Effluents Treatment Processes. A Short Review

The issue of effluents loaded with toxic pollutants resulting from industrial activities, as well as solutions to reduce and eliminate them, is and will be a domain of interest for the vast majority of researchers. On this background, this paper outlines and develops the general elements as well as the current stages of research in the field of Ultrafiltration (UF) Membrane technology applied to various industrial sectors. The parameters and their influence on the efficiency of the UF process, the fundamental characteristics of the materials as well as various solutions for the improvement and maintenance of the membrane materials were also reviewed. Therefore, in order for a membrane material to be as efficient as possible in UF processes, the following aspects must be taken into account: the optimal operating conditions of the UF process, the morphological and hydrophilicity characteristics of the membrane material, as well as the origin and composition of the effluent.
