RO System

1、 述:

1.Overview

反渗透又称逆渗透,一种以压力差为推动力,从溶液中分离出溶剂的膜分离操作因它和自然渗透的方向相反,故称反渗透。根据各种物料的不同渗透压,就可以使用大于渗透压的反渗透压力达到分离、提取、纯化和浓缩的目的,即对膜一侧的料液施加压力,当压力超过它的渗透压时,溶剂会逆着自然渗透的方向作反向渗透。从而在膜的低压侧得到透过的溶剂,即渗透液;高压侧得到浓缩的溶液,即浓缩液。反渗透与其它分离过程相比,有如下优点:

As an important component of membrane technology, reverse osmosis, its components are porous asymmetric osmotic membrane, mainly used for the separation of substances in the solution of the molecular level, so that the material was graded, concentrated and purified. Reverse osmosis, also known as reverse osmosis, a pressure difference as a driving force, from the solution separation of solvent separation of the membrane operation, because it is the direction of natural infiltration and reverse, so that reverse osmosis. Depending on the osmotic pressure of the various materials, the reverse osmotic pressure greater than the osmotic pressure can be used to achieve the purpose of separation, extraction, purification and concentration, i.e., applying pressure to the liquid side of the membrane, and when the pressure exceeds its osmotic pressure , The solvent will reverse the direction of natural infiltration reverse osmosis. So that a permeated solvent, i.e., a permeated liquid, is obtained on the low pressure side of the membrane; and a concentrated solution, i.e., a concentrated liquid, is obtained on the high pressure side.

The separation of large and small molecules solute mainly depends on the porosity of the membrane, that is, the adsorption, exclusion, blocking and sieve of the membrane on the large and small molecular solutes. Sub-effect, separation of physical and chemical factors than the physical factors are more important, and membrane on both sides of the solution of the osmotic pressure difference, so the greater the pressure on both sides of the membrane, the higher the desalination rate. Reverse osmosis compared with other separation process, has the following advantages:

3、反渗透膜:

3.Roll reverse osmosis membrane

 目前卷式反渗透膜是反渗透的最主要组成部分膜元件类似一个长信封状的膜口袋,开口的一边黏结在含有开孔的产品水中心管上使给水水流从膜的外侧流过,在给液料压力下,使淡液料通过膜进入膜口袋后汇流入产品液料中心管内并在膜页之间设有导流层与支撑层,根据物料的不同性质,膜页之间分为宽通道与窄通道,工作压力5.0Mpa,具有抗压抗污染强,不易堵塞、可长时间高效连续运行整个工艺分离效果好,操作简单,再生性能好等特点

The membrane reverse osmosis membrane is one of the most important forms of reverse osmosis, the membrane element is similar to a long envelope-like membrane pocket, and the opening side is bonded to the product water center tube containing the opening. The plurality of membrane pockets are wound on the same product center tube so that the feed water flows from the outside of the membrane, and the liquid material is allowed to flow into the liquid material center tube through the membrane into the membrane pocket after the liquid feed pressure, In order to facilitate the flow of the product liquid in the membrane bag, in the envelope of the membrane bag is covered with a layer of liquid material flow guide fabric layer; in order to make the liquid evenly through the membrane surface and to the liquid flow to disturb, In the film bag and the membrane between the liquid to the material channel is covered with a barrier layer. The volume of the membrane-type reverse osmosis element is different from the conventional filtration flow direction, and the liquid material is introduced from the end of the membrane element and flows in the direction parallel to the membrane surface. The separated product water is perpendicular to the membrane surface. Membrane into the product water film bag, therefore, to form a vertical, horizontal cross the flow of each other. The particulate matter in the liquid material remains in the liquid (gradually formed in concentrated water) and is taken away by the horizontal liquid stream. If the liquid flux of the membrane element is too large or the recovery is too high (refer to the excess Guidelines), the greater the likelihood that salt and colloids will remain on the membrane surface. Concentration is too high will form a concentration of polarization, colloidal particles will pollute the surface of the membrane, roll reverse osmosis membrane core tube as shown below:
