FILTREX FILTRATION SYSTEM
样品过滤系统要点
样品过滤(Sample filtraion)1.过滤器最终的设计就是防止分析器被阻塞。
但假如滤膜更换的太频繁，或是由于阻塞导致停机太久，那么就需要更好的过滤系统。
2.过滤器可分为两种，一是偶尔的情况下去除颗粒。
第二种连续式的过滤时，有自清功能的过滤器是必要的条件。
滤膜材质(filter media)对于灰尘颗粒选择适当的滤膜是非常重要的。
指定太好的滤膜将会导致成本价格的增加及过度的保养周期。
对于液态样品，过滤到8μm以下就可以保护马达及轴承了；过滤到2μm以下就可以保护光学系统；过滤到1μm以下就可以满足GC样品阀的需求。
对于气体，0.6μm的滤膜已经可以过滤90%的状况。
滤膜寿命取决于样品粒子浓度、网目及滤膜材质种类。
此外，烧结材质不好清理，且易碎。
(A)保护型过滤器(Protective filter)1.过滤器：Y型过滤器适合于制程上有合适保养点的类型。
这类设备通常是保养项目之一而且很容易买到。
典型例子如图所示。
通常，其滤网的网目为100mesh。
安装设计，通常依图示安装，可有效提升过滤效果。
2.仪器保护过滤器：通常用在弹策式过滤器及线上。
圆状(blowl-type)弹策式过滤器适用在仪器空气系统，广泛用于bypass模式。
(B)自清式过滤器1.自清式过滤探头(Back-Purged Filter Probe)在侦测器使用过滤器是没有用的，因为安装在入口的困难度很高。
所有有使用过滤器的地方应该使用自动排程方式的BACKWASHING来清洗过滤器。
当制程中含大量固体时即需要该类型的过滤器，若是希望透过管子来提取回收样品则是不切实际的做法。
另外可选择另一种方式，一种热分离装置，固定于探头附近。
像是喷射炉顶气体的应用，气体都是灰尘和湿气。
一个成功的样品前处理方法，应该是利用一个热蒸气过滤器装载在一个可切换动力的滤头顶部。
一个双重过滤头过滤器可使用高压氮气自动开关及清洗(如下图)。
当然这类过滤器的保养费用比手动清洗过滤器多许多。

硅藻土过滤在文献中的英文表述
硅藻土过滤在文献中的英文表述英文回答：Diatomaceous earth (DE) filtration is a water treatment process that uses a filter media made of the fossilized remains of diatoms, microscopic algae with glass-like cell walls. DE filters are used to remove particles, including cysts, bacteria, and viruses, from water.DE filters are typically used as a pre-filter to remove particles before the water is passed through a membrane filter. DE filters can also be used as a stand-alone filter for the removal of particles from water.DE filters are made up of a cylindrical tank with a perforated inner cylinder. The DE filter media is placed between the inner and outer cylinders. Water is pumped into the tank and flows through the DE filter media, which traps particles. The filtered water is then collected from the bottom of the tank.DE filters are relatively inexpensive and easy to operate. However, DE filters can be difficult to clean and can generate a large amount of waste.中文回答：硅藻土过滤是一种水处理工艺，它使用由硅藻（一种具有玻璃状细胞壁的微观藻类）的化石遗骸制成的过滤介质。

反渗透膜过滤机使用注意事项
反渗透膜过滤机使用注意事项英文回答：Precautions for Using Reverse Osmosis MembraneFiltration Machines.Reverse osmosis (RO) membrane filtration machines are essential appliances for providing clean and safe drinking water. However, to ensure optimal performance and longevity, it is crucial to adhere to several important usage guidelines:1. Regular Filter Replacement:RO membranes have a finite lifespan and requireperiodic replacement to maintain efficiency. The frequencyof replacement varies depending on water quality and usage patterns, but it is typically recommended to change the membrane every 6-12 months or as per the manufacturer's instructions. Failure to replace the membrane on time canlead to reduced filtration capacity, increased contaminants, and potential damage to the system.2. Proper Maintenance:Regular cleaning and maintenance are essential to prevent scaling and clogging of the RO membrane. This involves flushing the system periodically with cleaning solutions or using a water softener to reduce mineral buildup. Additionally, it is important to check for any leaks or malfunctions and address them promptly to ensure optimal operation.3. Suitable Water Source:RO filtration systems are designed to treat tap wateror other municipal water sources. Using untreated or contaminated water can damage the membrane and compromise the quality of the filtered water. It is advisable to have the water tested beforehand to ensure compatibility with RO filtration.4. Proper Installation:The RO filtration system should be installed by a qualified professional. Improper installation can lead to leaks, damage to the components, and reduced filtration efficiency. It is essential to follow the manufacturer's instructions carefully and ensure that all connections are secure and airtight.5. Adequate Water Pressure:The RO filtration process requires a minimum water pressure to operate effectively. Most systems require a pressure of at least 40 pounds per square inch (psi). If the water pressure is too low, it can affect the filtration rate and the removal of contaminants.6. Storage and Handling:RO membranes are delicate and should be handled with care. Avoid touching the membrane surface and store it in a cool, dry place when not in use. Freezing or exposing themembrane to high temperatures can damage its structure and reduce its efficiency.7. Environmental Conditions:RO systems should be operated in a clean and well-ventilated environment. Extreme temperatures, humidity, or dust can affect the performance and lifespan of the components. It is advisable to keep the system away from direct sunlight and other sources of heat.8. Troubleshooting:If you encounter any problems with your RO filtration system, such as reduced flow rate, strange noises, or leaks, it is important to troubleshoot the issue promptly. Checkfor any blockages in the filters or tubing, inspect the membrane for damage, and ensure that all connections are secure. If the problem persists, contact the manufactureror a qualified technician.中文回答：反渗透膜过滤机使用注意事项。

BECO depth filter sheets are inserted be-tween the filter elements and compressed.For sheet filtration, a feed plate, a BECO depth filter sheet and a filtrate plate are used alternately.For cake filtration, the filter pack consists of a combina-tion of cake frame, filtrate plate, and an intermediate BECO depth filter sheet. The cake frame is used for holding the solids.For step filtration, a baffle plate enables two-stage sheet filtration or primary precoat filtration followed by second-ary sheet filtration.The filter elements are de-signed to ensure secure inser-tion of the BECO depth filter sheet. Support rods below the filter pack are therefore not required.The product channels of the filter elements are sealed via the BECO depth filter sheet; no additional gaskets are required. This ensures that only the filter element and the BECO depth filter sheet are in contact with the product. The filter elements are manu- factured following cGMP guide- lines.45Minimized product loss through• high safety due to enclosed design• specially designed filter elements allow for complete emptyingCIP/SIP capability• the enclosed filter pack enables cleaning of the system without BECO depth filter sheets• sterilization with BECO depth filter sheets• no inaccessible corners or addi t ional installation effort • no dead spaces through special support of the BECO depth filter sheets• easy to clean due to sanitarydesign of the filter elements • cleaning validation possible on request (IQ/OQ)High flexibility through • different filter types • five plate sizes 200 x 200, 400 x 400, 600 x 600, 800 x 800 and 1000 x 1000 mm 1• cake frames with different widths for cake filtration and separation of high particleconcentrations • comprehensive range of types available for selectingthe appropriate BECO depth filter sheetPioneering filtration through• ideal flow distribution and product supply due to opti-mum design and configura-tion of the supply channels • uniform cake structure en- sured by optimum distribution of the material to be filtered• proper airflow due to the special design of the product channels situated at the top • good dry-blowing of the cake• optimum support of the BECO depth filter sheet based on tubular grid orribbed plate • sealing of the product chan-nels via the BECO depthfilter sheet Simple handling through • placement and accurate positioning of the BECOdepth filter sheet with theaid of the support noses/ cams at the filter elements • free cleaning of the filter (discharge of the BECO depth filter sheets andcakes downwards into a collecting tray)1200 x 200, 800 x 800 and1000 x 1000 mm withPP or PVDF available only67The filter chassis consists of a fixed front cover and two carrier bars that are connected to the cross member on the opposite side.

纯化水系统流程原理
纯化水系统流程原理Water purification systems are essential for ensuring access to clean and safe drinking water. These systems are designed to remove impurities and contaminants from water, making it suitable for consumption. The process of purifying water involves several steps, each serving a specific purpose in eliminating harmful substances.纯化水系统对于确保获得清洁安全的饮用水至关重要。
这些系统旨在从水中去除杂质和污染物，使其适合饮用。
纯净水的过程涉及几个步骤，每个步骤都有特定的目的，可以消除有害物质。
One of the primary methods used in water purification systems is filtration. Filtration involves passing water through a porous material, such as sand or activated carbon, to trap and remove particles and impurities. This step helps to remove larger contaminants such as sediment, debris, and microorganisms from the water.在纯化水系统中使用的主要方法之一是过滤。
过滤涉及将水通过多孔材料（如沙子或活性炭）以捕获和去除颗粒和杂质。
这一步骤有助于从水中去除像沉淀物、杂质和微生物等更大的污染物。
反渗透设备的工作原理
反渗透设备的工作原理Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water. 反渗透（RO）是一种水净化技术，它使用半透膜从饮用水中去除离子、分子和较大的颗粒。
The process of reverse osmosis involves applying pressure to the water on one side of the semipermeable membrane, forcing pure water through while holding back the contaminants. 反渗透的过程涉及在半透膜的一侧向水施加压力，迫使纯净水通过，同时阻止污染物进入。
The semipermeable membrane in an RO system only allows water molecules to pass through, effectively filtering out impurities, such as salt and other minerals. 反渗透系统中的半透膜只允许水分子通过，有效地过滤掉杂质，如盐和其他矿物质。
Reverse osmosis systems are commonly used in both residential and commercial settings to improve the taste, odor, and overall quality of drinking water. 反渗透系统通常用于家庭和商业场所，以提高饮用水的口感、气味和整体质量。

过滤（Filtration）基础知识
过滤（Filtration）基础知识过滤(Filtration)基础知识第1节概述一、慢滤池滤速慢：V＝0.1-0.3 m/h表面生长一层滤膜（1－2个星期后）效果：浊度可降到0，可不消毒。
机理：微生物吞食细菌微生物分泌出起凝聚作用的酶藻类产生氧气，起氧化作用。
但生产效率低，1－3月后堵塞，需刮掉滤膜，重新补砂。
二、快滤池及其机理条件：滤速大于10 m/h必须先投加混凝剂作用：去除浊度，浊度<5度，同时可去除一部分细菌、病毒机理：表层细砂层粒径为0.5mm，滤料孔隙率为80um，但进入滤池的颗粒尺寸大部分小于30um，但仍能被去除。
不光是简单的机械筛滤，还有接触粘附的作用。
主要有两个过程：迁移和粘附迁移是颗粒脱离流线接近滤料的过程，主要由以下作用力引起：拦截、沉淀惯性扩散水动力（非球形颗粒在速度梯度作用下发生转动）对于这几种力的大小，目前只能定性描述。
粘附：物理－化学作用力（范德华引力、静电力、以及一些特殊化学力）但表层滤料的筛分作用也不能排除，特别是在过滤后期，当滤层中的孔隙尺寸逐渐减少时。
应用：给水处理原水－混凝沉淀/澄清－过滤原水－微絮凝－过滤（微絮凝过滤）原水－加药－过滤（接触过滤）废水处理原水－生物处理－过滤第2节快滤池一、快滤池分类普通快滤池虹吸滤池重力滤池压力滤池移动罩冲洗滤池二、普通快滤池的构造组成：集水渠洗砂排水渠滤料层承托层配水系统管廊：浑水进水管清水出水管初滤水冲洗来水冲洗排水四大阀门（至少）过滤过程：最大过滤水头损失1.5－2m工作周期：过滤开始－冲洗结束＝12－24h三、过滤方式1．变水头等速过滤随着过滤进行，滤层孔隙率减少，水头损失的增加，滤池内水位自动上升，自由进流，以保持过滤速度不变。

东丽中空纤维超滤膜系统运行前预处理说明
东丽中空纤维超滤膜系统运行前预处理说明
东丽东丽中空纤维超滤膜是膜分离技术精密过滤的一种，因其操作运行稳定，在生活饮用水净化，工业用水处理和精细化工用水净化、除菌等方面得到广泛应用。
超滤膜分离水处理系统的运行主要分为以下几个方面。
超滤膜分离水处理系统运行前的预处理
由于原水成分复杂，各物质含量差异很大，因此在进入超滤反渗透设备之前，必须要进行必要的预处理，去除各种有害杂质，保证处理效果和处理设备的正常运行。
一般的预处理设备采用是集絮凝沉淀和砂滤于一体的自动设备，全自动机械控制，能够自动排泥、自动反洗。
同时出水浊度小于1NTU，含有一定的余氯，防止微生物的滋生，满足超滤进水要求。
超滤膜分离水处理系统反洗
原水经滤筒通过滤膜，由于杂质被截留在超滤膜表面，东丽膜的过滤阻力逐渐增加，过滤水量会随时间下降，这时候通过反洗就可以恢复膜通量。
正常运行时超滤反洗分为加氯反洗和脱氯反洗，加氯反洗可以有效防止微生物的滋生，最大程度的洗脱有机物，脱氯反洗主要是除去过量的余氯，保证出水余氯合格，满足后面的除盐工艺。
加氯反洗一般控制反洗水的余氯量在3~5mg/L。
超滤膜分离水处理系统停机备用反洗
停机备用反洗，又称为解列加氯反洗，同正常运行的加氯反洗相同，作用在于防止微生物的滋生。
超滤和反渗透膜分离水处理系统因其独特的结构和性能，在环境保护和水资源再生方面异军突起，并迅速推广到纺织、电力、食品、冶金、石油、机械、生物、制药、发酵等各个领域，都得到了很好的效果，在各领域都有着广泛的应用前景。
