Abstract: In order to improve the lifespan of the semi-permeable membrane or the yield of the reverse osmosis system in the treatment of drinking water by means of reverse osmosis, the invention provides a device for treating drinking water with at least one reverse osmosis vessel which is divided into at least two chambers by at least one semi-permeable membrane, wherein a first chamber has an inlet for the water to be treated and an outlet for the concentrate, and the second chamber has an outlet for the treated water, wherein the device comprises at least one pressure vessel which is connected to the outlet for the treated water via a line, wherein the device is designed in such a way that, in an idle state, treated water flows out of the pressure vessel, through the semi-permeable membrane and into the first chamber.

Abstract: The present invention provides a membrane separation process comprising a pressurized feed of solution that is combined with a repressurized, internal circulation of a concentrated solution. This combined flow of feed solution and concentrated solution may be introduced to either end of pressurized vessels containing membranes and this direction of flow is periodically reversed. This combination of repressurized internal circulation and reversal of the direction of flow allows for manipulations of concentration gradients both along the length of membranes in the pressure vessel and concentration gradients within the boundary layers at the surface of the membranes

Abstract: Systems and methods for acoustically-enhanced membrane separation are described. The system may generally include a separation membrane and an acoustically-responsive structure positioned proximate the upstream side of the separation membrane. The system may further include a transducer for generating an acoustic field, wherein the acoustic field causes microstructures extending from the acoustically-responsive structure to oscillate and thereby create streaming effects in the region between the distal ends of the microstructures and the upstream side of the separation membrane. These streaming effects can prevent or remove separation membrane fouling, prevent the formation of cake layers on the separation membrane, and/or remove cake layer formed on a separation membrane.
