陶氏4英寸超滤膜的运行方式
陶氏4英寸超滤膜的运行方式可分为循环模式和死端模式两种，根据原水的水质情况选择不同的运行方式。

今天，小编就给大家介绍下陶氏4英寸超滤膜的运行方式吧。

1、死端过滤
原水以较低的错流流速进入膜管，浓缩水以一定比例从膜管另一侧排出，产水在膜管过滤液侧产出。

死端过滤的操作成本低，但回收率和系统的出水能力可能会受到限制，水回收率通常是90%~99%，由原水中微粒的浓度来决定，当原水悬浮物和胶体含量较低时选用死端过滤方式，例如水源为井水、自来水等，工业水系统很多按死端过滤模式设计。

2、循环过滤
当原水中悬浮物含量较高时，就需要通过减少回收率来保持纤维内部的高流速，这样就会造成大量的废水。

为了避免浪费，排出的浓水就会被重新加压后回到膜管内，这就称为循环模式。

这会降低膜管的回收率但整个系统的回收率仍然很高。

在循环模式中，进水连续的在膜表面循环，循环水的高流速阻止了微粒在膜表面的堆积，并增强了通量。

当原水悬浮物和胶体含量较高时选用循环过滤方式，如水源地为地表水。

上述就是陶氏4英寸超滤膜的运行方式，希望对大家有所帮助。

IntroductionUltrafiltration (UF) involves pressure-driven separation of materials from a feed solution. The technology achieves separation through sieving and is used to remove particulate and microbial contaminants, but does not remove ions or molecules of low molecular weight. The process typically operates with a feed pressure of 4 to 100 psig (0.28 to 6.9 bar). UF plants are automated and have low operational labor requirements. Depending on the feed water quality, these systems can require frequent cleaning. UF membranes generally may have a service life of five years or longer, depending on system operations. UF technology is commercially available in tubular, hollow-fiber, plate and frame, flat sheet, and spiral wound configurations.UF membranes reject solutes ranging in size from 0.005 microns and larger. Figure 1 provides a guide to the relationship between common material sizes, separation processes, and pore size measurements. The UF membrane process separates molecules in solution on the basis of size. The pore size and molecular weight cut-off (MWCO) are often used to characterize a membrane. The pore size is the nominal diameter of the openings or micropores in the membrane expressed in micron (micron meters µm). The MWCO is the molecular mass or weight of a solute that rejects greater than 90 percent. The unit of measurement for MWCO is the Dalton (D).Different membrane materials with the same nominal MWCO may have differing solute rejection. Pore size distribution and uniformity rather than the chemical nature of the membrane material may cause this effect. Because factors other than pore size or MWCO affect the performance of membranes, challenge studies are used to demonstrate membrane performance and benchmark different membranes.Figure 1: Material Size and Membrane Process GuideThe DOW Ultrafiltration hollow fiber membrane shown in Figure 2 is 1.3 mm outside diameter and 0.7 mm inside diameter and is made from PVDF polymer. The fibers are strong because of a combination of the polymer type,The 0.03 μm nominal pore size combines high filtration performance and high flux. The smaller pore size provides stabile long term filtration performance compared to microfiltration hollow fiber membranes. Dow has taken its Ultrafiltration technology to a new product format, referred to as IntegraPac TM modules and skids. This range includes interconnecting end caps that reduce skid capital costs and engineering design efforts.2. Description of DOW ™ Ultrafiltration IntegraPac ™ Module2.1 IntegraPac TM Module FeaturesThe DOW Ultrafiltration IntegraPac TM modules are made from high strength, hollow fiber membranes and are engineered to reduce design and fabrication requirements with features and benefits including:∙ 0.03 µm pore size for removal of bacteria, viruses, and particulates, a 6 log removal of bacteria, a 2.5 log removal on viruses and a <2.5 SDI guarantee with proper operation∙ PVDF fibers which offer strength, chemical and fouling resistance which allows for extended membrane life and consistent long term performance∙ Outside-In flow configuration which allows higher TSS feed waters, while maintaining reliable system performance and producing high quality filtrateInnovative end-cap design enables direct coupling of modules reducing the need for piping and manifolds. The outside-in flow configuration allows the use of highly effective air scour cleaning which enhances particle removal and improves recovery. A dead-end flow format achieves higher recovery and energy savings. The module housing design eliminates the need for separate pressure vessels while the vertical orientation allows easy removal of air from cleaning and integrity testing processes.Figure 2: Wall Cross Section of the Hollow FiberThe IntegraPac TM module is shown in Figure 3. There are six connections on each module. The top end cap includes 4”DN 100 concentrate ports and an 1½” DN 40 union for the. The bottom end cap includes 4” DN 100 feed ports and a 3/8” air inlet connection on the side allowing for easy access. Included with the module are the couplers, air fitting, and transparent filtrate elbow. The IntegraPac TM skid offering is shown in Figure 4.Selective ActiveArea0.3 mm Wall ThicknessFeed Outside to InFiltrateSubstructureFigure 3: IntegraPac TM ModuleFiltrateConcentrateFeedAirConnectionF i g u r e 4: I n t e g r a P a c ™ S k i d C o m p o n e n t sFeed flow enters and is distributed into the modules through the side feed ports located on the bottom end cap. Feed flow enters the module on the outside of the fiber. The air connection is located on the side of the bottom end cap and is used for air scouring and integrity testing. The concentrate (discharge of waste flows from the outside of fiber) and filtrate ports (inside of fiber) are located on the top cap.Table 1: IntegraPac TM Module and Skid ConnectionsModule DN 100 (4 inch) Coupler DN 40 (1.5 inch) Threaded Union 3/8 inch Threaded (G3/8”) Skid DN 100 (4 inch) FlangeDN 150 (6 inch) Flange DN 65 (2.5inch) FlangeTable 1 shows the type and size of the connections for the IntegraPac ™ modules. 2.2 I NTEGRA P AC ™ M ODULE AND S KID S PECIFICATIONSTable 2 shows dimensions and specifications for the IntegraPac TM modules as depicted in Figure 5.

Figure 7 provides the installation details for DOW™ IntegraPac TM modules.Figure 7: Installation™ Drawing for IntegraPac™ IP 51 and IP 77 Modules3. Shipping and StorageTo control bacterial growth and prevent damage caused by fibers drying out, the DOW TM Ultrafiltration IntegraPac TM modules are wetted and stored in a non-hazardous standard storage solution containing pH buffered food-grade 1% wt. sodium metabisulfite (SMBS). At the end of the manufacturing process, storage solution is automatically injected into the modules and all inlet and outlet ports are sealed using plastic discs, couplings, and threaded plugs. If the modules will be exposed to low temperatures, glycerin can be added to the storage solution to prevent freezing. The modules are sealed in a plastic bag prior to boxing. Depending on the total number of modules and method of shipping, the modules are either shipped on pallets as shown in Figure 8 below or in crates. Skid components (underframe, air scour piping, filtrate piping) are shipped in a separate boxes or crates.As part of the quality assurance program, all DOW™ IntegraPac™ modules are tested for integrity and performance (“wet tested”) at the factory, prior to packaging and s hipment.Storage solution is automatically delivered into the module housings prior to sealing of the module ports. The target volume of storage solution used for each module is 4L (1 gal) for IP-51; and 6L (1.6 gal) for IP-77. After adding storage solution and sealing the openings, the modules are enclosed in plastic bags prior to boxing for dust protection. The storage solution volume and complete sealing of the module ports and openings help ensure a stable solution environment during transportation and storage of new modules.The bagged modules are stored in cardboard boxes, with one module per box. Saddle-shaped cushion inserts are located at both ends of the box and along the module to support and protect the modules from damage during shipping and handling. Depending on the total number of modules and required shipping method, the boxed modules are either palleted or crated for transportation. Other skid parts are placed in crates and shipped with the modules.Mechanical damage to module housing, membrane, and connections may result if the module, boxed module, pallet or crate is dropped, and otherwise mishandled. The modules should be handled with care, with particular attention during transportation.Figure 8: Pallet of IntegraPac™ Modules for ShippingStorage of New IntegraPac™ Modules:Modules are recommended to be shipped and stored in their original packaging separate from the system racks, and loaded into the system just prior to start-up. There may be cases where the customer prefers to pre-install the modules on the system racks; for example, to allow factory acceptance testing of packaged or mobile systems prior to shipping, or work scheduling at site to eliminate the separate step for module loading.These guidelines should be followed for storage of new DOW TM IntegraPac™ modules:∙Keep modules in original factory packaging.∙To minimize the potential for leakage of storage solution, modules should be stored in horizontal position.∙To prevent collapse of the boxed modules, limit vertical stacking to four layers of modules.∙Store inside a cool and dry building or warehouse, away from sources of heat, ignition, and direct sunlight. An ambient temperature of 20°C (68 ºF) to 35°C (95 ºF) is recommended for ideal storageconditions.∙Temperature limits for modules during shipping and storage is 1ºC (33.8 ºF) to 40ºC (104 ºF). Modules must be protected from freezing or excessive heat during shipping and storage. In order to avoidabrupt variations in temperature; equalization should be allowed to occur at a maximum temperaturedifferential of +/- 1°C (1.8 ºF) per minute. If freezing conditions are anticipated during the customer’sshipping and storage of modules, please notify DW&PS at the time of order placement. Glycerine may be added to the storage solution at the factory prior to shipping to allow for shipment and storage atfreezing conditions.∙Sealed modules may be stored up to 1 year from date of manufacture, at the recommended storage conditions described above and in the original packaging.Storage of modules installed on a skid:Modules (hollow fibers) installed during assembly of a skid should not be allowed to dry out. Dry membrane fibers will irreversibly lose flux. Blank or “dummy” modules are available to accurat ely build and assemble a skid. Consult the manufacturer regarding modules installed on a skid and not planned for operations within 7 days. UF systems are designed to run continuously and membrane systems perform better when operated continuously. However, in reality UF systems will start-up and shutdown on some frequency. Before the UF system shuts down, the system must be cleaned using air-scour and filtrate water backwash to prevent bio-growth in the UF system.The water used for backwash before shutdown should not contain chemicals. Any feed water and backwash chemical dosing used should be stopped before the last cleaning and shutdown. After cleaning, all valves on the UF system should be closed to seal the system.To avoid leakage in the module housing end caps and clamps, the backpressure in the modules should be controlled when the UF system shuts down, especially in case of non-scheduled shutdowns, e.g. power failure or emergency shutdowns.When the system is down for greater than 96 hours, note the following:∙The module should not dry out. Dry membrane fibers will irreversibly lose flux at any time.∙The system should be adequately protected against bio-growth, flushed for duration of 30 to 60 minutes once a day, or operated every 24 hours. If flushing with feed water, the quality should be <10 NTU or<10 mg/L TSS.∙The system should be protected against temperature extremes. The UF system can be shut down for96 hours without adding storage solution or taking additional precautions for microbiological fouling.Storage of modules off skid:For cases of long-term shutdown where the modules will remain out- of-service for an extensive period of time (weeks to months), the modules can be removed from the skid and stored to eliminate maintenance operations. If the module has been in service, a Chemically Enhanced Backwash (CEB) or Clean In Place (CIP), followed by an air scour and backwash (without chemicals) should be conducted before decommissioning the equipment. Add 4 and 6 liters of storage solution into the feed port of an IP-51 and IP-77 IntegraPac™ module respectively. The module should be kept in the horizontal position at the time of filling, with the remaining ports and openings sealed. Once the target volume of storage solution is added into the module, seal the feed ports and store the modules in the horizontal position. Modules should be placed in a plastic bag for protection and keeping the modules clean.If the modules will be exposed to freezing conditions glycerin should be added to the storage solution. It is recommended that food grade glycerin be added to the storage solution at the target strength detailed in Table 5. Enough solution should be added to wet the hollow fibers. Completely filling the modules with solution is not required. Modules prepared as described can be stored for 90 days. Consult the manufacturer for storage durations greater than 90 days.Warranty return of modules:Review the project warranty information for authorization instructions before shipping modules for return. To prepare a module for shipment drain the module, plug or seal the openings/ports, and secure the module on a pallet or in a crate.Table 4: Glycerin addition for Freezing Point Depression4. DOW Ultrafiltration IntegraPac™ Process Description4.1 Process OperationsThe basic operating conditions for the DOW Ultrafiltration IntegraPac™ modules and Skids are shown in Table 6 below. Operating parameters for the cleaning steps are provided in the section that describes cleaning.Figure 9: Filtration Step for DOW UF IntegraPac Modules and SkidsNormal operation refers to the routine operating sequence of a system using the DOW TM Ultrafiltration IntegraPac™ module and includes the operating and backwash steps. Consult Dow for commissioning procedures. At initial start up the modules are flushed using a “forward flush” to remove any residual chemicals or trapped air from the module. The flush occurs on the outside of the fibers and does not filter the feed water to produce filtrate. After the forward flush is discontinued the modules can be placed in the operating mode. An operating cycle ranges from 20 to 90 minutes in duration. While operating, 100% of the feed water is converted to filtrate. This is also referred to as dead end filtration. As contaminants are removed and deposited on the hollow fiber membrane surface during the operating step the transmembrane pressure will rise. At the end of the preset operating cycle time, a backwash sequence commences.Figure 10: Air Scour Step for DOW UF IntegraPac™ Modules and SkidsThe backwash mode occurs automatically usually on a preset time basis. The steps include an air scour, draining by gravity, backwash through the top outlet, backwash through the bottom outlet, and a forward flush. The air scour step is used to loosen particulates deposited on the outside of the membrane surface. Air is introduced on the outside of the fibers using only the hold up water volume of the module. Displaced feedflow/concentrate is allowed to discharge through the top of the module for disposal. After 20 to 30 seconds of continuous or intermittent air scour the module is drained by gravity.Figure 11: Air Scour Gravity Drain Step for DOW UF IntegraPac™ Modules and SkidsAfter the gravity draining step, the first backwash step is performed. Filtrate flow is reversed from the inside of the fiber to the outside and backwash flow is removed from the module housing through the top outlet. Figure 12: Top Backwash Step for DOW UF IntegraPac™ Modules and SkidsThe second backwash step is performed to remove backwash water through the bottom outlet. Filtrate continues to flow from the inside of the fiber to the outside and backwash flow is removed from the module housing through the bottom outlet of the module, ensuring the entire length of fibers have been cleaned. The backwash steps can be repeated numerous times depending on the degree of fouling. After backwash is complete, a forward flush is performed to remove any remaining large particulates and air trapped on the outside of the fibers. After a backwash, the modules are returned to the normal operating mode.Figure 13: Bottom Backwash Step for DOW UF IntegraPac™ Modules and SkidsCEB operation refers to a chemically enhanced backwash. The frequency of a CEB is dependent on the feed water quality. On high quality feed waters a CEB may not be required. The CEB process is programmed to occur automatically but the frequency can be field adjusted after gaining site specific operating experience. The CEB is performed using UF filtrate and either an acid, or alkali chemical. The alkali solution can be a combination of oxidant and caustic to more efficiently clean contaminants from the membrane surface. Selection of chemicals is made according the DOW Ultrafiltration applications guidelines and understanding of the foulants in the feed water.Figure 14: Forward Flush Step for DOW UF IntegraPac™ Modules and SkidsThe CEB is performed using the steps of a normal backwash except during a CEB, chemical is dosed into the backwash water and a soak step is added after the second backwash step. In addition the CEB can be performed at reduced flow, usually 50% of the backwash flux.Figure 15: Chemically Enhanced Backwash "Top" Step for DOW UF IntegraPac™ Modules and SkidsThe soak is performed for 5 to 20 minutes and allows time for the chemical to react with contaminants that have attached to the membrane surface or penetrated the fiber wall. Intermittent air scour can be applied during the soak step. After the soak a routine backwash including air scour, gravity drain, top and bottom backwash, and forward flush is performed to remove any remaining particulates and purge residual chemicals. After a CEB and at the start of the operating step, the initial filtrate produced may be sent to waste to remove residual chemicals. This step is dependent on the system piping and valve design and the downstream requirements for the filtrate. Figure 16: Chemically Enhanced Backwash "Bottom" step for DOW UF IntegraPac™ Modules and SkidsCIPA clean in place (CIP) is an offline operation that includes backwashes and chemical recirculation and soaking to clean the hollow fibers. The CIP is an on demand operation. It can be an automated process but is most often conducted manually. The frequency of a CIP is dependent on the feed water quality and routine fouling control strategy but can range from 1 to 6 months. Prior to a CIP the routine backwash steps including air scour, draining, backwash through the top outlet, and backwash through the bottom outlet are performed. Thebackwash steps can be repeated multiple times to remove contaminants or foulants not requiring chemical removal. After completing the backwash steps, the module is drained by gravity to remove excess water and prevent dilution of the CIP chemical solution. The CIP chemical solutions are recirculated through the modules on the outside of the hollow fibers for 30 minutes through a chemical mixing and solution tank. A portion of the recycle stream can be passed through the hollow fibers and recycled to the chemical cleaning tank. A cartridge filter is used to remove particulates from the CIP solution during recycle. Note that the CIP solution can be heated to 40ºC to improve effectiveness for removing contaminants from the hollow fibers. The CIP solution pH can be measured during the cleaning process and refreshed with chemicals to maintain the target pH and effectiveness of the solution. A soak is performed after the initial recycle step for 60 minutes or longer depending on the degree of fouling that has occurred. After the soak step, CIP chemicals are again recycled through the modules on the outside of the hollow fibers for 30 minutes. Air scour for short durations can be performed during the soak and recycle steps to prevent channeling of the solution through the module. When the recycle is completed an air scour is performed and then the module is drained to remove the concentrated chemical solution. The top and bottom backwash and the forward flush steps are also performed to remove any remaining particulates on the outside of the fibers. After a CIP and at the start of the operating step, filtrate may be sent to waste to remove residual chemicals held in the fiber or module. The CIP steps described above are for a single alkali or acid chemical solution. If both an acid and alkali cleaning are required, the CIP steps would be repeated for each chemical solution.Figure 17: Clean in Place Cleaning Step for DOW UF IntegraPac™ Modules and Skids4.2 PretreatmentDOW Ultrafiltration IntegraPac™ Modules and Skids designs are based on qualified feed water conditions as shown in Table 7. The UF IntegraPac™ Modules and Skids can tolerate period excursions in feed water quality as shown as the maximum allowable in Table 7. If the feed water quality is outside of the design basis range Dow should be consulted to determine if a pilot study is needed to confirm performance or if a pretreatment step is necessary. Also, if the membrane filtration system is designed and installed to the conditions below but the feed water quality is not maintained, please consult Dow Water & Process Solutions.2 Residual in filtrateDepending on application, a safety screen of 100 - 300 microns is recommended on the feed before the UF IntegraPac™ Modules and Skids. In seawater applications, a strainer size of 100 – 150 microns is recommended to prevent the growth of barnacles and mussel larvae in upstream, process pipework and tanks. A variety of technologies can be used such as self-cleaning screens and filters and bag, cartridge, or disc filters. Depending on the type of water or range of feed water parameters other pretreatment processes such as oxidation, coagulation, clarification and media filtration may also be needed.4.3 CleaningSummary of InformationThe process operating parameters for the cleaning steps are provided in Table 8 below.4.4 FoulingThere are four types of fouling common to UF operations including particulate, biological, inorganic, and organic.Particulate fouling is caused by suspended solids, colloids, and turbidity. To reduce particulates in UF feed water coagulation, sedimentation, clarification, and filtration are often used. The common cleaning method for particulate fouling is air scour and backwash.Biological fouling is caused by the growth of microorganisms. Using in-line chemical feed of chlorine or biocide or eliminating nutrients by using PAC, GAC, or coagulation, can reduce biological fouling. The cleaning method for removal of biological fouling is Chemically Enhanced Backwash (CEB) with oxidizers or biocides (NaOCl,H2O2, SBS). Shock chlorination can also be effective for biological fouling control. Inorganic fouling is caused by the precipitation of inorganics on the membrane. The rate of inorganic fouling can be controlled through oxidation/precipitation and/or filtration as pretreatment to the UF or in some cases reducing the hardness of the feed water. The recommended cleaning method for removal of inorganic fouling is chemically enhanced backwash with acid at pH 2 (HCl, H2SO4, Citric, Oxalic Acid).Organic fouling is caused by organics adsorbing on the membrane (silt, organic acids, humus). PAC, GAC, or coagulation can be used to control the rate of organic fouling. The common cleaning method for removal of organic fouling is CEB with alkali at pH 12 (NaOH).5.

陶氏反渗透膜超滤膜活性炭过滤安全操作及保养规程前言
陶氏反渗透膜、超滤膜和活性炭过滤是现代水处理技术中常用的三
种方法，可广泛应用于饮用水、制药、食品饮料、化工和电子等领域。

本文旨在介绍这三种技术的基本原理、安全操作要点和保养规程，以
确保使用者在使用这些设备时遵循正确的操作程序，从而最大限度地
提高设备的使用寿命和处理水的质量。

一、陶氏反渗透膜
1. 原理
陶氏反渗透膜（Reverse Osmosis，RO）是一种利用高压迫使水通
过半透膜，将水中的溶质和离子分离的技术。

反渗透膜是一种半透膜，膜孔径小于100埃，可以有效地过滤掉水中的细菌、病毒、溶质和游
离离子，从而达到除盐、脱色、脱菌和净化水的目的。

反渗透膜通常
是由多层净化材料构成，保证传质的效率和质量。

2. 安全操作要点
反渗透膜在使用过程中需要特别注意以下操作要点：
•避免使用不符合要求的水源；
•确保给水水压稳定；
•保证压力容器密封性完好；
•定期检查反渗透膜和各种管路的状况；。

陶氏超滤膜2880技术参数1. 引言超滤膜是一种常用于分离和过滤液体的薄膜，其孔径较小，可以有效地去除溶质和悬浮物。

陶氏超滤膜2880是一种高效、高通量的超滤膜，本文将介绍其技术参数及特点。

2. 技术参数陶氏超滤膜2880具有以下主要技术参数：2.1 膜材料陶氏超滤膜2880采用聚酰胺材料制成，聚酰胺是一种具有良好耐化学性和机械性能的聚合物材料。

该材料在超滤过程中能够有效地分离溶质和悬浮物，并保持较高的通量。

2.2 孔径大小陶氏超滤膜2880的孔径大小为0.01微米（μm），这意味着只有小于等于0.01μm的颗粒才能穿过该膜。

这样可以有效地去除大部分溶质、病毒、细菌等微小颗粒，从而实现液体的分离和纯化。

2.3 通量陶氏超滤膜2880具有较高的通量，通量是指单位时间内通过膜面积的液体体积。

该膜的通量可达到5000升/平方米/小时（L/m²/h），这意味着在相同时间内可以处理更多的液体，提高生产效率。

2.4 耐温性能陶氏超滤膜2880具有良好的耐温性能，可在较宽的温度范围内使用。

其耐温范围为0℃至45℃，适用于大部分工业生产环境下的超滤过程。

2.5 PH范围陶氏超滤膜2880适用于广泛的PH范围。

其适用PH范围为1至13，可以在酸性、中性和碱性环境下进行超滤过程。

2.6 操作压力陶氏超滤膜2880的操作压力为最大10巴（bar），压力越高，通过膜的液体流速越快。

然而，在选择操作压力时需要注意不要超过该膜所能承受的最大压力，以免损坏膜材料。

3. 特点与应用陶氏超滤膜2880具有以下特点和应用：3.1 高效分离由于陶氏超滤膜2880的孔径较小，可以有效地去除溶质和悬浮物，从而实现高效的分离和纯化。

该膜广泛应用于水处理、食品与饮料生产、药品制造等领域，可用于去除杂质、浊度、微生物等。

3.2 高通量陶氏超滤膜2880具有较高的通量，可以在相同时间内处理更多的液体。

这使得该膜在大规模工业生产中具有重要意义，能够提高生产效率和节约成本。

超滤膜的工作原理和操作方法超滤膜的工作原理和操作方法一、工作原理过滤是使液体通过多孔过滤介质以分离其中所含的固体颗粒的一种操作。

过滤介质截阻颗粒而让液体通过，随着被分离的颗粒变小，要求介质的通道也要变小。

如果颗粒小到亚微细粒的程度，膜孔大小就要趋近于能阻止溶液中大分子的通过。

这种利用半透膜的微孔过滤以截留溶液中大溶质分子的操作称为超滤，而这样的半透膜称为超滤膜。

超滤的驱动力是压力，通常高达1.0MPa。

运用液压迫使溶液透过膜并按溶质分子大小、形状等差异，把大溶质分子阻留在膜的一侧，成为浓缩液; 而小分子的溶质则随溶剂透过膜到另一侧，成为透过液流出。

如果将所得浓缩液用水稀释，再进行超滤，可使料液中的低分子溶质进一步随透过液流出，而高分子物质逐步得到提纯，这样的过程称为全滤(如图8-4)。

超滤具有分离和提纯的作用。

1. 分离作用图8-4 超滤原理示意图1—进料2—浓缩液3—清液4—超滤膜低分子质量的溶质随溶媒一起透过滤膜，高分子质量的溶质被截留，因此，料液被分为带有低分子溶质的透过液和带有高分子溶质及残留低分子溶质的浓缩液。

2. 提纯作用由于分离，提高了浓缩液中总固体里高分子量溶质的百分率，因此，提纯了高分子溶质。

在透过液中，低分子溶质由于从高分子溶质中分离出来，也得到了提纯。

二、超滤膜(一)超滤膜的膜渗机理料液在超滤膜内的流动问题比较复杂，简单的床层流动理论不能充分解释膜内的流动，它不是单纯属于一般毛细管内层流的机理。

通常膜渗机理有下述两种模型：1. 毛细流动模型在这种模型中，溶质的脱除主要靠流过微孔结构的过滤或筛滤作用，半透膜阻止了大分子的通过，按这一模型建立的流动是毛细孔中的层流流动。

2. 溶解扩散模型在这种模型中，假定扩散质的分子，先溶解于膜的结构材料中，而后再经载体的扩散而传递。

因为分子种类不同，溶解度和扩散度也就不同。

实际上，两种模型在膜渗传递中都可能存在，但反渗透以溶解扩散机理占优势，而超滤则以毛细流动机理占优势。
