Zusammenfassung:A method of at least partly restoring functional capacity of at least one membrane (2b) for filtering or separating a flow of liquid particle mixture, wherein the at least one membrane (2b) is situated in a membrane housing (2a) having at least a feed inlet (3) and a permeate outlet (4), wherein the method comprises the steps of emptying the membrane housing (2a) at least partly of liquid particle mixture via an emptying outlet (10), and subjecting the at least one membrane (2b) to a jet of ozone gas crosswise the at least one membrane (2b), which jet is injected into the membrane housing (2a) via an ozone inlet and leaves the membrane housing (2a) via an ozone outlet.
