Abstract: The present invention relates to a method for preventing microbial growth on a filtration membrane during desalination process. The method comprises that the membrane is exposed to a low concentration of performic acid by continuously or intermittently introducing performic acid to the membrane surface. When performic acid is added according to the present invention to the water flow, there is no significant reduction in the water flux through the membrane.
