A filtration media is formed from at least one structured polymeric layer, wherein a structured surface is defined within the layer. Layers may be configured as a stack that has the structured surfaces defining a plurality of ordered inlets open through a face of the stack and corresponding ordered fluid pathways, thereby forming an ordered, porous volume. The ordered fluid pathways may be defined by a plurality of flow channels formed within the structured surfaces of the structured layers, or may be defined by a plurality of protuberances formed in an ordered pattern within the structured surfaces of the structured layers.

The method of retrofitting a pre-existing reverse osmosis system according to claim 3 further comprising between the third-disconnecting and the third-inserting steps: removing a flow obstruction present in the flow of waste water from the second outlet port of the reverse osmosis membrane vessel. 5. The method of retrofitting a pre-existing reverse osmosis system according to claim 4 further comprising after the removing step: transmitting the removed flow obstruction remotely from a site of the retrofitting as physical proof of conducting the retrofitting. 6. The method of retrofitting a pre-existing reverse osmosis system according to claim 3 wherein the first-inserting, the second-inserting and the third-inserting steps are done at the same time because the integrally-packaged first sub-assembly, the integrally-packaged second sub-assembly, and the integrally-package third sub-assembly are all (i) flow-connected and (ii) physically mounted together as one assembly.
