一、超滤膜
超滤膜是一种加压膜分离技术，即在一定的压力下，使小分子溶质和溶剂穿过一定孔径的特制的薄膜，而使大分子溶质不能透过，留在膜的一边，从而使大分子物质得到了部分的纯化。超滤技术的优点是操作简便，成本低廉，不需增加任何化学试剂，尤其是超滤技术的实验条件温和，与蒸发、冷冻干燥相比没有相的变化，而且不引起温度、pH的变化，因而可以防止生物大分子的变性、失活和自溶。在生物大分子的制备技术中，超滤主要用于生物大分子的脱盐、脱水和浓缩等。超滤法也有一定的局限性，它不能直接得到干粉制剂。对于蛋白质溶液，一般只能得到10~50%的浓度。家用工业用都可以。超滤技术的关键是膜。膜有各种不同的类型和规格，可根据工作的需要来选用。
NO.1 ultrafiltration membrane
Ultrafiltration membrane is a pressurized membrane separation technology, that is, under a certain pressure, the small molecule solute and solvent pass through a special film with a certain aperture, and the large molecule solute cannot pass through, remaining on one side of the membrane, so that the large molecule substance is partially purified. The advantages of ultrafiltration technology are simple operation, low cost, no need to add any chemical reagents, especially the experimental conditions of ultrafiltration technology are mild, there is no phase change compared with evaporation and freeze-drying, and it does not cause changes in temperature and pH, so it can prevent the denaturation, inactivation and autolysis of biological macromolecules. In the preparation technology of biological macromolecules, ultrafiltration is mainly used for desalination, dehydration and concentration of biological macromolecules. Ultrafiltration method also has certain limitations, it can not directly obtain the dry powder preparation. For protein solutions, generally only 10-50% concentration can be obtained. It can be used for domestic and industrial purposes. The key of ultrafiltration technology is membrane. The membrane has a variety of different types and specifications, which can be selected according to the needs of the work.
二、纳滤
纳滤，介于超滤与反渗透之间。现在主要用作水厂或工业脱盐。脱盐率达百分之90以上。反渗透脱盐率达99%以上但，若对水质要求不是特别高，利用纳滤可以节约很大的成本。
NO.2 nanofiltration
Nanofiltration, a cross between ultrafiltration and reverse osmosis. It is now mainly used for water plants or industrial desalination. The desalting rate is more than 90 percent. Reverse osmosis desalination rate of more than 99%, but if the water quality requirements are not particularly high, the use of nanofiltration can save a lot of costs.
三、反渗透
反渗透，是利用压力表差为动力的膜分离过滤技术，源于美国二十世纪六十年代宇航科技的研究，后逐渐转化为民用，目前已广泛运用于科研、医药、食品、饮料、海水淡化等领域。
用作太空水、纯净水、蒸馏水等制备;酒类制造及降度用水;医药、电子等行业用水的前期制备;化工工艺的浓缩、分离、提纯及配水制备;锅炉补给水除盐软水;海水、苦咸水淡化;造纸、电镀、印染等行业用水及废水处理。
NO3. reverse osmosis
Reverse osmosis, is the use of pressure gauge difference as the power of membrane separation filtration technology, originated from the United States in the 1960s aerospace science and technology research, after gradually transformed into civilian, has been widely used in scientific research, medicine, food, beverage, seawater desalination and other fields.
Used for the preparation of space water, purified water, distilled water, etc. Alcohol manufacturing and tempering water; Pre-preparation of water for pharmaceutical and electronic industries; Concentration, separation, purification and water preparation of chemical process; Boiler make-up water desalt soft water; Desalination of seawater and brackish water; Water and wastewater treatment in papermaking, electroplating, printing and dyeing industries.
反渗透膜 先酸洗 后碱洗
每个反渗透系统都会发生污染需要清洗，由于污染发生时通常不是只有一种污染物，因此典型的清洗过程通常按要求包括低pH值清洗和高pH值清洗两大步骤。
不同的污染物应采用不同的清洗剂进行清洗，碱性清洗主要用于去除微生物或者有机污染物，酸性清洗主要用于去除结垢。应根据污染物类型和膜类型来选择清洗剂，以避免损坏膜。清洗药剂的使用顺序应据实际问题确定，通常的清洗顺序是先进行酸洗，然后进行碱洗。在某些情况下，如果污染主要为有机物或者微生物，可以先碱洗，后酸洗，最后再进行一步碱洗。把碱洗作为最后一步的重要原因在于它能使得经过酸洗后的膜孔充分张开，以恢复产水流量。。
Every reverse osmosis system will be contaminated and need to be cleaned, because there is usually not only one pollutant when pollution occurs, so the typical cleaning process usually includes two steps of low pH cleaning and high pH cleaning as required.
Different pollutants should be cleaned with different cleaning agents, alkaline cleaning is mainly used to remove microbial or organic pollutants, acid cleaning is mainly used to remove scale. Cleaning agents should be selected according to the type of contaminant and membrane type to avoid damaging the membrane. The order of use of cleaning agents should be determined according to the actual problem, the usual cleaning order is first pickling, and then alkali washing. In some cases, if the contamination is mainly organic matter or microorganisms, it can be washed first, then pickling, and finally a step of alkali washing. The e important reason for using alkaline washing as the last step is that it allows the membrane pores to open sufficiently after pickling to restore the water production flow.
