Abstract:
1. A filtration system, comprising one or more filter modules and one or more fluid couplings for coupling the filter modules to (i) a fluid distributor or (ii) further filter modules, wherein the filter modules are configured as wound filter modules comprising one or more filter elements having edge regions in which, in each case, two or three of the edge regions are sealed in a fluidtight manner, with two of the edge regions sealed in a fluidtight manner running substantially in an axial direction between two end sides of the filter module, each filter element comprising two filter membranes and a drainage layer located in-between, with single or double permeate outlets formed from openings in a remaining filter element edge(s) at the filter module end side(s), with said openings providing fluid communication between the drainage layer and the fluid coupling(s); the filter modules comprise one or two end walls, with at least one end wall having permeate outlet openings and one or more ducts for concentrate fluid; the fluid couplings have at least one duct for permeate fluid, the duct for permeate fluid is connected to the permeate outlet openings and the fluid coupling has at least one duct for concentrate fluid isolated in a fluidtight manner from the duct for permeate fluid.
