Apparatus and System for Deionization

摘要

There is provided a membrane module comprising a membrane package comprising at least two membrane sleeves, wherein the membrane package is configured to allow essentially free flow of a first stream inside the sleeves and essentially free flow of a second stream between each two adjacent sleeves, and a frame, configured to support the membrane package, such that part of each of four surfaces of the membrane package is affixed to predetermined areas in the frame, forming a module having separate spaces configured to facilitate separate flows of the first stream and the second stream through the membrane package. The invention further provides a multi-modular stack, comprising at least two membrane modules and at least one membrane, wherein the first stream is fully enclosed inside each module and the second stream flows through all the modules.

1. A membrane module comprising:
a membrane package comprising at least two membrane sleeves, wherein each sleeve comprises a first and a second membrane sealed together along two parallel edges of said first and said second membranes, and wherein said two membrane sleeves are connected along two edges perpendicular to the sealed edges of said first and said second membranes, forming two membrane package sides having unsealed sleeve edges, wherein the membrane package is configured to allow essentially free flow of a first stream inside the sleeves and essentially free flow of a second stream between each two adjacent sleeves, wherein the first stream flow is perpendicular to the second stream flow; and a frame, configured to support the membrane package, such that part of each of the four surfaces perpendicular to the two membrane package sides having unsealed sleeves edges is affixed to predetermined areas in the frame, leaving the unsealed sleeves open to the flow of the first stream and forming a module having separate spaces configured to facilitate separate flows of the first stream and the second stream through the membrane package.
