Abstract

PURPOSE: The cleaning element of high cleaning effect and endurance for hollow reverse osmotic membranes which is composed of the polyvinyl formal resin foam (PVF sponge) of the circular cylindrical shape having a diameter larger than the inside diameter of the hollow reverse osmotic membrane and a length larger than the diameter.
CONSTITUTION: When the cleaning element 2 composed of the PVF sponge of the circular cylindrical shape having a diameter larger than the inside diameter of a hollow reverse osmotic membrane 3 and a length larger than the diameter is inserted into the said membrane, the sponge is compressed and passes in the same while it is rubbing the membrane surface, thus it has less degree of wear with respect to a fixed treating volume of water and is stable directionally as compared to spherical cleaning elements, hence it has higher cleaning efficiency.
