专利申请范围本专利是关于通过流体的流动使螺旋状板材的边缘部和膜面的接触来实现防止膜面污染的方法的研究。这种至少边缘是由软质材料组成的螺旋状板安装在管型或棒型渗透膜的纵向上,边缘部分在膜面的附近,并与其呈接触状态。发明的详细说明本发明是关于在使用半透膜或其它的渗透膜进行流体扩散、分离或浓缩等处理的过程中,无论内压式或外压式管状渗透膜或膜支持体防止污物向棒型渗透膜面析出或者附着的方法。
Patent Application This patent is a study on a method for preventing contamination of the membrane surface by contacting the edge portion of the spiral plate with the membrane surface by the flow of the fluid. At least the edge is a helical plate made of a soft material mounted in the longitudinal direction of the tubular or rod permeable membrane with the edge portion in the vicinity of and in contact with the membrane surface. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the use of a semipermeable membrane or other permeable membrane for the treatment of fluid diffusion, separation, or concentration, regardless of whether the internal pressure or external pressure tubular permeable membrane or membrane support Rod permeable membrane surface deposition or attachment method.
