Abstract: A purification system is disclosed comprising a first reverse osmosis stage having a high pressure side and alow pressure side and a second reverse osmosis stage having a high pressure side and a low pressure side. The high pressure side of the first reverse osmosis stage outputs a yield stream that is split into a recycle stream and a concentrate stream. The low pressure side) of the first reverse osmosis stage receives the concentrate stream and outputs a purified stream. The high pressure side) of the second reverse osmosis stage receives the purified stream from the first reverse osmosis stage and outputs a reject stream) which is recycled to the high pressure side of the first reverse osmosis stage. The low pressure side of the second reverse osmosis stage outputs a final permeate product. U) 01o (N Co Ul) co (N ' rLO Vf CD (0 c rO U' Uf) (D U UlU) OD cc m 4) LO C

Abstract: Systems and processes for purifying and concentrating a liquid feed stream are disclosed. In the systems, the concentrated liquid output from the high pressure side of a reverse osmosis stage is used as the draw solution in the low pressure side of the reverse osmosis stage in a configuration called osmotically assisted reverse osmosis. This reduces the osmotic pressure differential across the membrane, permitting high solute concentrations to be obtained, hastening the purification of the liquid. Reduced system pressures are also obtained by arranging multiple osmotically assisted reverse osmosis stages in a cross-current arrangement. Overall system energy consumption is reduced compared to conventional thermal processes for high concentration streams.

Abstract: This invention relates to reverse osmosis systems and processes for purifying liquid streams in which reverse osmosis stages are staged in a partially cascading, cross-current arrangement. These arrangements permit reduction in osmotic pressure differential, purification of solutions with very high solute concentrations, and operation at reduced pressures with similar separation efficiencies compared to conventional arrangements. tO cu co CoN LLi U)

Abstract translation: 公开了用于净化和浓缩液体进料流的系统和方法。 在该系统中，反渗透级的高压侧输出的浓缩液体在反渗透级的低压侧用作渗透辅助反渗透的配置中的汲取溶液。 这降低了跨过膜的渗透压差，允许获得高溶质浓度，加速了液体的净化。 通过将多个渗透辅助反渗透级布置在交叉电流布置中也获得了降低的系统压力。 与传统的高浓度气流热工艺相比，整体系统能耗降低。
