ABSTRACT:
An apparatus and process for tubular membrane separation, such as reverse osmosis or ultrafiltration, with an arrangement for removing undesirable deposits from the semipermeable membrane surfaces. For the removal of the deposits, elastic elements are passed, together with the feed solution being treated, through the tubular modules lined with semipermeable membranes, separated from the solution, and are recycled with a fresh supply of the solution from a tank, so that the semipermeable membranes are continuously cleaned while separating a part of the solution by permeation therethrough.
