All raw waters contain microorganisms such as bacteria, fungi, virus, algae, which have the ability to reproduce and form a biofilm under favorable conditions, like on the surface of a reverse osmosis (RO) or nanofiltration (NF) membrane, where nutrients dissolved in the
water accumulate. Like all the depositions on membrane surfaces, biofouling may affect the performance of the
membrane systems. Depending on the importance of the phenomenon, it can even cause severe mechanical damages of the membrane elements or create corrosion of the metallic parts of the unit. Sometimes, biofilm is able to pass into the permeate decreasing its quality and causing a potential sanitary problem.
