There is a demon in the northwest, and some article information about membrane products will be released above, and there should be above.

At present, all I see are Dow films from Shanghai Baozi**, and other brands are not very clear.

There's a lot of branding, which kind of brand do you want.

The Dow film in the United States is the best, but it is difficult to buy **, and there are other brands such as Huitong film, Shihan film, Jiuzhang, and Haina.

The membrane is not bad, and the quality is OK.

At present, many domestic brands of reverse osmosis membranes, such as Dow, Toray, Hydeneng, LG membrane, and Shihan ZLD membrane, are all good, with good quality, high desalination rate and large permeability.

The most used films on the market are Dow and Hyde films.

It's not bad at the moment, if you have to separate the high and low, you can go to the Northwest Magic Net to have a lively time, and there are no people in there, and you dare to say it.

Another one seems to be in the middle of the heavens.

Advantages: high filtration accuracy, reverse osmosis membrane filtration accuracy up to microns, filtered water can be directly drinkable.

It is easy to operate, compact in structure and low in maintenance cost.

Disadvantages: Wastewater will be generated.

It needs to be replaced regularly.

Hanston. Hanston HSD-RO75G-1503 is Hanston's best-selling double-outlet water purifier, and it is also the main product.

This is an ultrafiltration RO water purifier, 6-level filtration, more than the general RO water purifier with one more layer of ultrafiltration membrane, which is equivalent to buying a RO machine and ultrafiltration machine, if it is a maternal and infant family, if you want to drink mineral water, you can also drink pure water, you can also use ultrafiltration water to wash vegetables and make tea, etc., saving RO wastewater drainage and usage, and can also extend the life of RO filter element, which is very good.

Hanston Water Purification Equipment has the R&D capabilities of GPAN ultrafiltration membrane technology and reverse osmosis water purifier, and uses imported raw materials and molds to design a series of products suitable for the Chinese market. Kitchen water purifiers, water purifiers, direct drinking water purifiers, water purifiers, commercial water purifiers, and energy direct drinking water dispensers are in a leading position in China's industry.

Advantages of the Hanston brand:

1. Chain reticular molecular clusters. This structure of ultrafiltration membrane has super toughness, which changes the staggered structure of traditional ultrafiltration membranes. Effectively increase the filtration accuracy of the ultrafiltration membrane, which is not easy to break.

2. Core isolation technology. Nitrogen is stable and easy to generate, in the finished product, nitrogen protection technology is used to avoid air from entering the water purifier, when the product is not used, if the core components of the water purifier are in direct contact with the air, the service life of the product is greatly reduced.

3. Nano smooth using the principle of nanoscienceThe molecular arrangement is more neat, the surface of the membrane looks smoother, and the membrane wall is smooth, which has high anti-fouling performance.

4. Arc cycle technology. In terms of the characteristic technology that combines aesthetics and purification processes, the laboratory uses the circular arc technologyFor example, the arc-shaped stainless steel end cap can effectively resist pollution and facilitate thorough backwashing, although it increases the production cost in the production process.

5. MTF nanotechnology. In the process of forming the filter material, ultrasonic and electromagnetic wave treatment are used, and then the filter material is blended, the filter element is arranged to achieve regularity, and the tap water is filtered through multiple channels to ensure the precision purification of every drop of water.

Reverse osmosis membranes are used in a wide range of applications, and many industries are inseparable from them. At first, the use of reverse osmosis membrane was relatively simple, but with the development of time, reverse osmosis membrane has a broader development space.

Reverse osmosis membranes are developed for the purpose of desalination, and the requirements for membranes are only for the separation of inorganic salts and water. At present, the trend of changing the traditional medium-pressure membrane to low-pressure membrane or ultra-low-pressure membrane is very active, and its development trend is summarized as follows:

In the field of desalination, desalination is carried out at a high pressure (5-7 MPa) to an ultra-high pressure (MPa). For brackish water desalination, it will develop in three aspects: desalination (groundwater, river water), wastewater treatment (industrial wastewater, municipal sewage) and ultrapure water (electronic industry water, medical water). The pressure will change from medium pressure (3-4 MPa) to low pressure (1-2 MPa) or even ultra-low pressure (below 1 MPa).

At the same time, there will be greater development in the field of concentration of useful substances.

At present, in seawater desalination, the composite membrane has successfully achieved a high desalination rate. In terms of brackish water desalination, it can be said that it is the trend of the times to change the traditional medium-pressure membrane to low-pressure membrane or ultra-low-pressure membrane, and keep the desalination rate unchanged (or increase).

Another development direction of reverse osmosis membrane engineering application is the organic combination application of reverse osmosis membrane assembly device and ultrafiltration, microfiltration, nanofiltration, EDI and other assembly devices, giving full play to the characteristics of various membrane separation technologies to form a complete system engineering to achieve the purpose of concentration, separation and purification.

In view of recent advances in RO technology, the following developments are expected in this field in the near future:

First, polymer membranes will be developed to remove small chloride organic molecules.

Second, inorganic RO membranes for separating hydrocarbon mixtures will be developed.

Third, based on the power membrane, inorganic and organic mixed material membranes will be developed.

Fourth, more advanced physical methods are used to understand the structure of the membrane and the structure of the liquid in the membrane.

Fifth, the pore size of the membrane is controlled by controlling the size of the polymer body and the density of the polymer in the pellets.

Sixth, the concept of polymer pellets will also be used in the design of composite membranes.

Seventh, on the basis of membrane pore size and polymer-solution interaction, a more precise transport theory will be developed.

Eighth, by controlling the membrane pore size and membrane solute interactions, membranes that can fractionate mixed solutes will be developed.

9. Membrane fouling will be controlled by the design of the membrane and the design of the membrane module.

Tenth, the mixed separation system of RO and other separation processes will increasingly infiltrate the chemical industry and related industries, and more and more chemical and biological reactions will be combined with membrane separation technology.
