Abstract

A SPIRAL MEMBRANE ELEMENT, IN WHICH AN ENVELOPED SEPARATION MEMBRANE (20) IS WOUND AROUND THE EXTERNAL CIRCUMFERENCE OF A PERMEATE WATER COLLECTION PIPE (60) TOGETHER WITH A FEED WATER SPACER (1). THE FEED WATER SPACER IS FORMED FROM FIRST WIRES (11) AND SECOND WIRES (12), EACH MEANDERING WITH A GENTLE CURVE FROM A FEED WATER INLET SIDE TOWARD A FEED WATER OUTLET SIDE, THE FIRST WIRES RUN ALONG ONE OF THE OPPOSING SURFACES OF THE SEPARATING MEMBRANE, ONE FIRST WIRE AND THE OTHER ADJACENT FIRST WIRE FORMING ONE OF THE FEED WATER PASSAGES (23, 24), THE SECOND WIRES RUN ALONG THE OTHER MEMBRANE SURFACE (22) OF THE SEPARATING MEMBRANE, ONE SECOND WIRE AND THE OTHER ADJACENT SECOND WIRE FORMING THE OTHER FEED WATER PASSAGE, AND THE FIRST WIRES AND SECOND WIRES PARTLY OVERLAP AND ARE BONDED AT THE OVERLAPPING POINTS.
