Abstract

A non-woven tubular component is claimed, for reverse osmosis applications with an internal membrane filter, with a tear-ope strip fitted to the porous tube. The design allows at least at a part of the non-woven tube to be ripped open, for ease of removal from the supporting tube when the membrane is worn out, without time being lost in the exchange operation.
