What are the advantages of household membrane technology?

The application of membrane technology and water treatment has the following advantages; 1.Treat all kinds of liquids and get high-quality filtered water; 2.The membrane process can be implemented with a simulator and can be operated continuously; 3.

The permeate has the potential to be recycled as process water or reused in a certain percentage. Of course, the application of membrane separation technology to water treatment also has some disadvantages; The compatibility of membranes is related to many factors such as the size of the pores, the pH of the water, and the temperature of the water; In some cases, fouling is easy to form, which makes the life of the membrane short in some special applications; Compared with traditional physicochemical treatment, the general investment cost is higher.

Membrane technology is used in water treatment, and its separation efficiency is related to the following factors; hydraulics and plastered solid loads; pressure and running water; the ratio of the diameter of the particles in the water to the pore size of the membrane; thickness and chemical properties of the membrane; Physical and chemical properties of particulate matter. Regarding the service life of the membrane, it is as short as only a few months, but it is usually 3 to 7 years, and some tubular membrane systems can be used for more than 15 years. There are many factors that affect the service life of the membrane, usually such as the performance matching of the feeding tank and pump, the pretreatment effect, the permeate storage device, and the cleaning system and effect of the membrane.

Fouling of the membrane is often an important factor affecting the membrane application, and it should be that fouling will reduce the flux of the membrane or increase the transfer pressure of the membrane. Membrane fouling can be solved with effective pretreatment or effective cleaning and backwashing.

With the continuous development of membrane technology, membrane technology has been widely used in many faces: 1Electricity;

2.Electron; 3.chemical and pharmaceutical;

4.Light; 5.Creature;

6.food and beverage;

7.Municipal; 8.environmental protection and other industries.

It has a wide range of applications and a large degree of industrial relevance. Comparison of the separation range of PF ultrafiltration membrane and microfiltration membrane.

In the field of water treatment, ultrafiltration technology can remove bacteria, viruses, heat sources and other colloidal substances in water, so it is used to prepare ultrapure water in the electronics industry, injections in the pharmaceutical industry, purification of various industrial water and purification of drinking water. In the food industry, ultrafiltration technology is gradually adopted in the production of dairy products, fruit juices, wines, condiments, etc., such as the separation of protein and low molecular weight lactose from water in milk or whey, the clarification and sterilization of fruit juice, the removal of colored proteins, polysaccharides and other colloidal impurities in wine, and the removal of bacteria in soy sauce and vinegar, which shows the advantages of economy, reliability and quality assurance compared with traditional methods.

In pharmaceutical and biochemical production, it is often necessary to separate and purify heat-sensitive substances, and ultrafiltration technology shows its outstanding advantages. Ultrafiltration to separate concentrated bioactive substances (such as enzymes, viruses, nucleic acids, special proteins, etc.) is quite suitable for drugs extracted from animals and plants (such as alkaloids, hormones, etc.), and there are often macromolecules or solid substances in the extract, which can be separated by ultrafiltration in many cases, so that the product quality can be improved.

In the field of wastewater treatment, ultrafiltration technology is one of the successful examples for the treatment of elucent water in electroplating processes. In the production of metal products such as automobiles and furniture, after the paint is deposited on the metal surface by electrophoresis, it is necessary to wash off the plating solution absorbed on the product with clean water. Washing to obtain 1 2% of the coating of the leaching wastewater, with ultrafiltration device to separate the clean water, the paint can be concentrated and reused for electrocoating, the obtained clean water can also be directly used for cleaning, can realize the recycling of water.

At present, most automobile factories at home and abroad use this method to treat electrocoating elument water.

Ultrafiltration technology can also be used for textile mill wastewater treatment. The desizing solution of the textile mill contains polyvinyl alcohol (PVA), which is used with ultrafiltration device **PVA, clean water**, and the concentrated PVA concentrate can be re-sized.

With the development of new membrane materials (functional polymers, inorganic materials), the temperature, pressure and solvent resistance of membranes have been greatly improved, and ultrafiltration technology will be more widely used in petrochemical, chemical industry and more fields.

Applications of microfiltration.

Microfiltration is mainly used to remove ultrafine particles larger than left and right in the solution, and its application is very wide, accounting for the first place in the current sales of membrane process surface industry.

In the process of water purification, microfiltration technology can remove bacteria and solid impurities, which can be used in the production of medicine and beverage water. In the preparation of ultrapure water in the electronics industry, microfiltration can be used for the pretreatment of ultrafiltration and reverse osmosis processes and for the final security filtration of products. Microfiltration technology can also be used to filter various alcoholic beverages such as beer and rice wine to remove yeast, mold and other microorganisms, clarify the product, and extend the storage period.

Microfiltration technology is also widely used in drug sterilization, biological detection and other fields.

Anzhi Star to help you answer the question of reverse osmosis technology features and its advantages?

Reverse osmosis technology is usually used in seawater, brackish water, water softening, wastewater treatment, and purification, concentration, and separation in the food, pharmaceutical industry, and chemical industry. In addition, reverse osmosis technology has also achieved good results in pre-desalination treatment, which can reduce the load of ion exchange resin by more than 90%, and the amount of regenerant in resin can also be reduced by 90%. As a result, it not only saves costs, but also contributes to environmental protection.

Reverse osmosis technology can also be used to remove particles, organic substances and colloids in water, which has a good effect on reducing the pollution of ion exchange resin and prolonging the service life.

Technical advantages: 1. Continuous operation, stable product water quality;

2. No need to regenerate with acid and alkali;

4. Produce ultrapure water with high yield (yield can be as high as 95%);

5. Simple installation and low installation cost.

Scientists have studied cells and found that animal cells have a very thin membrane called a cell membrane. It isolates the cell from the outside world. The structure of cell membranes is complex. It contains not only proteins, but also phospholipids, sugars, metal ions, and water, among others.

Don't look at this thin film, it can be very effective! In terms of permeability, all kinds of substances are not "treated equally", but are selective. "Green light" for some substances, unimpeded, so that they can enter the cell smoothly; For others, a red light is lit and "no traffic".

It in turn excretes secretions from the cells to the outside of the cells. Here, the cell membrane plays a role in regulating the exchange of substances inside and outside the cell.

The study of biofilms has led to a new technology – membrane technology. As a result, a wide variety of artificial films have emerged. Artificial membranes are widely used in separating liquid mixtures, brackish water and seawater desalination, sewage treatment, gas separation, purification, concentration of certain substances, etc.

The membrane of the glomeruli of the human kidney is an excellent filter, and when the blood flows through, except for red blood cells, white blood cells and macromolecular proteins, everything else flows through the "membrane" to the cyst cavity to form urine. Therefore, the artificial kidney must be designed with a membrane that does the same thing, otherwise, it will not become an artificial kidney. Artificial membranes are also used in the design of artificial gills.

The simple reason is that the gills of fish are actually special membranes that allow only oxygen from the water to pass through. Artificial gills have been made possible by breakthroughs in membrane technology, which can help humans conquer the blue ocean and unravel the mysteries of the underwater world.

Comprehensive performance of household films.

1. The state hunger removal rate of inorganic matter is lower than that of organic matter.

2. The removal rate of ionic solutes is worse than that of non-ionic solutes.

3. The ionic solute removal rate of ** is high, and the guess collapses in the low-price solute. For example, the removal rate of Al3+ ions is higher than that of Mg2+ and Na+ ions.

4. The solute removal rate of inorganic matter is related to the size of ions and hydrated ions. The larger the ionic radius or hydrated ionic radius, the higher the rejection rate.

5. The larger the molecular weight of the non-ionic solute, the higher the removal rate.

The reverse osmosis membrane adopts spike circle cross-flow filtration technology to automatically discharge sewage. The purified water quality is consistent and has a long service life.
