Claim:
1. A combination unit of multiple membrane shells, formed by bundling a plurality of membrane shells in parallel, wherein a raw water port and a concentrated water port of each of the membrane shells are respectively interconnected with those of an adjacent membrane shell, the combination unit of multiple membrane shells being formed with at least one shared raw water port and at least one shared concentrated water port which are respectively capable of being connected with a raw water pipeline and a concentrated water pipeline, correspondingly connected two raw water ports or two concentrated water ports of two adjacent membrane shells are interconnected by one adapter without using a clamp, each adapter forming a connection between two raw water ports or two concentrated water ports and wherein there is provided a seal extending around each adapter and wherein the seal is compressed by two adjacent membrane shells so as to seal the connection formed by the adapter, the combination unit of multiple membrane shells further comprising a binding firmware which is arranged at a periphery of the plurality of membrane shells bundled in parallel for combining the plurality of membrane shells into an integrated unit; wherein the binding firmware comprises a rigid or flexible binding tape that extends around the membrane shells and a pressure adjuster operatively connected between one of the membrane shells and the binding tape for preloading the binding tape and automatically adjusting the tension of the binding tape by using the pressure inside the membrane shells; and wherein each pressure adjuster comprises a preloaded bolt, a preloaded cushion block and a piston, and wherein the preloaded bolt is operative to position the preloaded cushion block and adjust a gap between a respective binding tape and the membrane shell in order to preload the binding tape.
