    • PROBLEM TO BE SOLVED: To solve a problem that in spiral-structured water treatment separation modules, an organic material is adsorbed at a membrane surface, occluding a polymer mesh structure and reducing the amount of water permeation, and the adsorbed organic material develops into a gel clump and becomes clogged in narrow portions of a gap between the membrane and a spacer, thus greatly degrading the amount of water permeated through the module.SOLUTION: This water separation module includes: a central pipe; a plurality of water separation membranes 11 attached to the central pipe and installed spirally around the central pipe so as to overlap with each other; and a spacer 12 located between the plurality of water separation membranes 11 on the side at which untreated water flows in. In the water separation module, irregularities having a size preventing interfere with the mesh shape of the spacer 12 and securing water flow paths are applied to the surface of the water separation membranes 9, 11, and thereby clogging of narrow portions of a gap between the membranes 11 and the spacer 12 can be suppressed.
    • 解决的问题为了解决在螺旋结构水处理分离模块中的问题,有机材料被吸附在膜表面,堵塞聚合物网状结构并减少水渗透量,并且吸附的有机材料 发展成凝胶块,并且在膜和间隔物之间​​的间隙的狭窄部分中被堵塞,从而大大降低了渗透通过模块的水的量。 解决方案:该水分离模块包括:中心管; 多个水分离膜11,其安装在中心管上并螺旋地安装在中心管周围以便彼此重叠; 以及位于未处理水流入的一侧的多个水分离膜11之间的间隔件12.在水分离模块中,施加防止间隔件12的网格形状干扰的尺寸和固定水流路的凹凸 到水分离膜9,11的表面,从而可以抑制膜11与间隔物12之间的间隙的狭窄部分的堵塞。 版权所有(C)2012,JPO&INPIT
