Abstract
Fibre web pipe as a carrier of membranes suitable for membrane filtration comprises a helically wound fibre web band, contg. weldable synthetic fibres, which are joined by ultrasonic welding. The inside of the pipe is sufficiently uniform, and has the necessary strength, to permit the deposition of a cellulose acetate membrane used for reverse osmosis without an interm. paper fibre layer. This reduces the flow resistance, and when membrane replacement is necessary. The complete unit is extracted from the press. support pipe for disposal.
