The concentrate of the first element becomes the feed to the second element and so on. The permeate tubes are connected with interconnectors (also called coupler), and the combined total permeate exits the pressure vessel at one side of the vessel.

Two membrane sheets are glued together on three sides, only with an opening towards the permeate pipe. The feed water flows across the membrane surface from one side to the other. Due to the high pressure in the vessel, a part of the water penetrates the membrane and this permeate water can only leave the PV through the permeate pipe, while the rest of the water - now more concentrated - leaves on the other side of the membrane , just flowing across the sheet.
