Abstract:

Concepts of the teardown washing of the abandoned reverse osmosis(RO)membrane elements are put forward.The teardown washing and its surface treatment are introduced.The integrality of the teardown elements and their salt penetration and water penetration performanced of the treated elements are analyzed.The capabilities of the treated elements are testified to be higher or lower than the desaltation rate of nano-filtration membrane.The technical and economic values of treated elements and the applicable fields of the elements are pointed out.

Key words: reverse osmosis membrane , teardown washing of membranes , surface treatment, application of abandoned membrane
