    • Described herein is a construction comprising (a) a support sheet having a base, comprising (i) a plurality of rails extending from the base wherein each rail of the plurality of rails extends continuously down a length of the support sheet and each rail comprises a first side surface and an opposing second side surface and a top surface; and (ii) a plurality of first protrusions extending from the base, wherein the plurality of first protrusions are located between the plurality of rails; and (b) a selectively permeable membrane having a first major membrane surface contacting at least the top surface of at least two rails enclosing a flow channel having a height extending between the base of the support sheet and the first major membrane surface, wherein the plurality of protrusions change the height of the flow channel along its length along the longitudinal axis of the flow channel.
    • 这里描述的是一种结构,其包括(a)具有基部的支撑片,该支撑片包括(i)从基部延伸的多个导轨,其中多个导轨中的每个导轨连续地向下延伸 支撑片和每个导轨包括第一侧表面和相对的第二侧表面以及顶表面; 和(ii)从所述基部延伸的多个第一突起,其中所述多个第一突起位于所述多个导轨之间; (b)具有第一主膜表面和第二主膜表面的选择性渗透膜,所述第一主膜表面至少接触包围流动通道的至少两个导轨的顶表面,所述流动通道具有在所述支撑片的基部和所述第一主膜表面之间延伸的高度,其中,所述多个 突出物沿流动通道的纵向轴线改变流动通道沿其长度的高度。
