Abstract: A filtering module, for example a nanofiltration or reverse osmosis module, is made of membranes arranged in a stack with flat sheets of feed channel spacer and permeate carrier. The stack has packs formed of two membrane sheets sealed on four sides and enclosing a permeate carrier. The packs alternate with sheets of feed channel spacer through the thickness of the stack. One or more permeate-collecting pipes pass through the thickness of the stack. The sheets of feed channel spacer have seals along two sides and around the permeate-collecting pipes. A module is formed by placing one or more stacks in a pressure vessel with a seal between the stack and the pressure vessel at a downstream end of the stack.
