This paper presents the results of research work conducted as part of a doctoral thesis and undertaken with the aim of resolving the problem of accelerated fouling of reverse osmosis membranes (made from spiral-wound polyamide), as a result of the deposition of colloidal particles (particulate fouling), the precipitation of inorganic salts (scaling) and the accumulation of living and/or dead biological matter (biofouling). The reverse osmosis modules affected form part of the Las Palmas III
