摘要： A frameless array unconfined in a modular shell, proves to be a surprisingly effective membrane device for withdrawing permeate from a substrate, the flux through the membranes reaching an essentially constant relatively high value because of the critical deployment of fibers of the array as a skein, arching in a buoyantly swayable generally parabolic configuration within the substrate, above at least one of the array's headers in which the terminal end portions of the fibers are potted. The length of each fiber must be greater than the direct center-to-center distance between the array's pair of headers. For use in a large reservoir, an assembly of the array and a gas distributor means has fibers preferably >0.5 meter long, which together provide a surface area >10 m . The terminal end portions of fibers in each header are substantially free from fiber-to-fiber contact. When used in a tank from which the permeate is withdrawn at a location low enough to overcome the transmembrane pressure differential of the fibers, the permeate is withdrawn under a vacuum induced by gravity. To increase flux, a pump may be used which provides a suction less than 75 cm of Hg. When used in combination with a gas-distribution manifold disposed beneath the skein so as to flow bubbles through it, the surfaces of the fibers are surprisingly resistant to being fouled by build-up of deposits of inanimate particles or microorganisms in the substrate. Membranes with high transmembrane pressure differential may be used, if desired, and permeate removed with a vacuum pump.
摘要翻译：未封闭在模块化壳体中的无框架阵列被证明是一种令人惊讶的有效的膜装置，用于从基板中提取渗透物，由于阵列的纤维作为绞纱的临界部署，通过膜的通量达到基本上恒定的相对高的值，在衬底内的浮动的摇摆般的抛物线构造中，在阵列的头部中的至少一个，其中纤维的末端部分被封装在其中。每个光纤的长度必须大于阵列对接头之间的直接中心到中心的距离。为了在大容器中使用，阵列的组件和气体分配器装置具有优选> 0.5米长的纤维，其共同提供表面积> 10m 2。每个集管中的纤维的末端部分基本上没有纤维与纤维的接触。当用于将渗透物排出到足够低的位置以克服纤维的跨膜压差的位置的罐中时，在由重力引起的真空下抽出渗透物。为了增加通量，可以使用提供小于75cm Hg的吸力的泵。当与设置在绞纱机下方的气体分配歧管组合使用以使气泡通过其时，纤维的表面令人惊奇地抵抗由于底物中无生命的颗粒或微生物的沉积物的积聚而被污染。如果需要，可以使用具有高跨膜压差的膜，并用真空泵除去渗透物。

摘要： During normal operation of a hollow fiber membrane in contact with dirty water, a fouling film is produced on the surface of the membrane. Despite the fouling film, the membrane affords a desirable initial stable transmembrane flux which decreases as a function of time by at least 20 %. A method is disclosed for cleaning the outer surface of a microfiltration (MF) or ultrafiltration (UF) semipermeable hollow fiber membrane after its initial stable transmembrane flux has been decreased to an unacceptably low level. The method is specifically applicable to any fiber used to withdraw purified water from dirty water, particularly water containing organic matter including beneficial bacteria and/or undesirable inorganic salts, where the viability of the bacteria population is to be maintained. The membrane is cleaned by flowing a cleaning fluid, preferably a biocidal oxidative electrolyte having an oxidizing anion and an associated cation through the clean, permeate-side of the membrane, at low pressure no more than the bubble pressure breakthrough, usually
摘要翻译：在与脏水接触的中空纤维膜的正常操作期间，在膜的表面上产生污垢膜。尽管膜具有污垢，膜提供了期望的初始稳定跨膜通量，其作为时间的函数减少至少20％。公开了一种用于清洁微滤（MF）或超滤（UF）半透膜中空纤维膜的外表面的方法，其中其初始稳定的跨膜通量降低到不可接受的低水平。该方法特别适用于从脏水中抽出净化水的任何纤维，特别是含有有机物质的水，包括有益细菌和/或不需要的无机盐，其中细菌群体的存活力将被维持。通过使清洁液，优选具有氧化性阴离子和相关阳离子的生物杀灭氧化电解质通过膜的清洁，渗透侧流动，在不超过气泡压力穿透的低压下，通常<300kPa（ 30 psig）用于MF或UF纤维。这样低的压力足以使电解质扩散通过膜和孔隙，通常包括生物膜，但不足够的电解液流过膜以在数量上杀死超过20％的污水中的活细菌。只有清洁周期短暂，才能满足此限制。这个时期只足以氧化毛孔内的有机物质，并杀死生物膜中的所有细菌。优选地，小于5％的细菌群体被抽取。当扩散发生时，在纤维的壁和生物膜中再次开放孔，当纤维恢复正常操作时，恢复的焊剂等于初始稳定焊剂的至少70％。
