    Reverse osmosis


    Reverse osmosis can effectively remove the dissolved inorganic, organic, bacteria, pyrogen and other particles in water. It is the most important part in the treatment of dialysis water. To understand the principle of reverse osmosis, we should first explain the concept of osmosis. The so-called permeation refers to the separation of two solutions with different concentrations by a semi permeable membrane. If the solute cannot pass through the semi permeable membrane, the water molecule with lower concentration will pass through the semi permeable membrane and reach the other one with higher concentration until the concentration on both sides is equal. Before the equilibrium is reached, the pressure can be gradually applied to the side with higher concentration, and the above-mentioned water molecular movement state will stop temporarily. At this time, the required pressure is called "osmotic pressure". If the applied force is greater than the osmotic pressure, the water movement will go in the opposite direction, that is, from the side with high concentration to the side with low concentration, This phenomenon is called "reverse osmosis". The purification effect of reverse osmosis can reach the level of ion, the rejection rate of monovalent ions can reach 90% - 98%, and the divalent ions can reach 95% - 99% (which can prevent the passing of substances with molecular weight greater than 200 daltons).

    The commonly used semi permeable membrane materials for reverse osmosis water treatment include fibrous plasma membrane, aromatic polyamides, polyimide or polyfuranes, etc. according to their structural shapes, they are spiral wound, hollow fiber and tubular. Among these materials, cellulose membrane has the advantage of high chlorine resistance, but its service life will be shortened under alkaline conditions (pH ≥ 8.0) or in the presence of bacteria. The disadvantage of polyamide is its poor tolerance to chlorine and chloramine.

    If there is no pre-treatment before RO, there will be dirt accumulation on the membrane, such as calcium, magnesium, iron plasma, which will cause the decline of RO function; Some membranes (such as polyamide) are easy to be destroyed by chlorine and ammonia chloride. Therefore, pre-treatment such as activated carbon and softener should be carried out before reverse osmosis membrane. Although the cost of reverse osmosis is high, because the pore size of reverse osmosis membrane is about 10 A or less, it can eliminate bacteria, viruses, pyrogens and even various soluble ions. Therefore, it is best to prepare this step when preparing water for dialysis.

    Water treatment methods include physical treatment and chemical treatment. Human beings have been treating water for quite a long time. Physical methods include the use of filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude impurities in water. The more important adsorption method is activated carbon adsorption. The barrier method is to pass water through the filter materials, so that larger impurities can not pass through, And then get clean water. In addition, physical methods also include precipitation method, that is, let the impurities with smaller specific gravity float on the surface of water to be fished out, or the impurities with larger specific gravity precipitate on the bottom of water to be obtained. The chemical method is to use various chemicals to transform impurities in water into substances that do less harm to human body, or to concentrate impurities. The oldest chemical treatment method should be adding alum into water. After the impurities in water are collected and the volume becomes larger, the impurities can be removed by filtration.

    It includes the removal of nutrients and disinfection of sewage by chlorination, ultraviolet radiation or ozone technology. Some wastewater treatment processes may not include all of the above processes according to the treatment objectives and water quality.

    The purified water treatment process depends on the quality of raw water.

    If the raw water is municipal tap water, the general process is

    Sand filter - activated carbon filter - softening (optional) - security filter - reverse osmosis - ultraviolet disinfection - water production

    If it is ordinary surface water, it should be sterilized and flocculant added before entering the above process.

    In case of well water, a filter for removing iron and manganese should be added after sand filtration.

    The water is recycled and purified.

    Quartz sand filtration is one of the most effective means to remove suspended solids in water. It is an important unit in advanced wastewater treatment, wastewater reuse and water supply treatment. Its function is to further remove the pollutants that have been flocculated in the water. It can achieve the purpose of water purification through the interception, sedimentation and adsorption of filter materials.


    Similar to reverse osmosis, ultrafiltration also uses semi permeable membrane, but it can not control the removal of ions, because the pore size of membrane is large, about 10-200a. Only bacteria, viruses, pyrogen and particles can be eliminated, but water-soluble ions cannot be filtered. The main function of ultrafiltration is to act as the pretreatment of reverse osmosis to prevent the reverse osmosis membrane from being polluted by bacteria. It can also be used in the final stage of water treatment to prevent the upstream water from being contaminated by bacteria in the pipeline. Generally, the difference between inlet pressure and outlet pressure is used to judge whether the filter membrane is effective or not. Similar to activated carbon, the back flushing method is usually used to remove the impurities attached to it.

    Ultraviolet disinfection

    Its bactericidal mechanism is to destroy the life genetic material of bacterial nucleic acid and make it unable to reproduce. The most important reaction is that the pyrimidine base in the nucleic acid molecule turns into dimer. Generally, the artificial ultraviolet energy of 253.7 nm wavelength of low-pressure mercury discharge lamp (sterilization lamp) is used. The principle of the ultraviolet germicidal lamp is the same as that of the fluorescent lamp, except that the fluorescent material is not coated inside the lamp tube, and the material of the lamp tube is quartz glass with high ultraviolet penetration rate. General ultraviolet devices can be divided into irradiation type, immersion type and flow type according to their uses.

    Ultraviolet germicidal lamp for water treatment

    Ultraviolet germicidal lamp for water treatment

    The ultraviolet ray used in the hemodialytic dilution water is placed on the pipeline between the water storage tank and the dialysis machine, that is, all dialysis water should be exposed to ultraviolet ray before use, so as to achieve the effect of thorough sterilization. Pseudomonas aeruginosa and Escherichia coli were the most sensitive to UV; On the contrary, Bacillus subtilis spores were more tolerant. Because ultraviolet disinfection is safe, economical, less selective for bacteria, and the water quality will not change, it has been widely used, such as drinking water on ships. It can kill all the bacteria in the water, such as egola, bassiala, Salmonella, and so on. It can submerge into the water center for 360 degrees to kill bacteria, which is three times as effective as the surface germicidal lamp. It can eliminate algae in water with remarkable effect and easy to use. It is suitable for filtration, water treatment, large and small pools, swimming pools and hot springs in various fishing grounds. The sterilization efficiency can reach 99% - 99.99%.

    Ultraviolet water treatment technology sterilization

    Ultraviolet sterilization mainly uses 254 nm ultraviolet light. This wavelength of ultraviolet light, even in a small amount of UV radiation dose, can also destroy a cell's life core - DNA, thus preventing cell regeneration, losing the ability to regenerate, making bacteria harmless, so as to achieve the effect of sterilization. As with all other UV applications, the size of the system depends on the intensity of the UV (the intensity and power of the irradiator) and the contact time (the duration of exposure of water, liquid, or air to UV).

    Ultraviolet water treatment technology -- eliminating ozone

    In industrial production, ozone is often used to disinfect and purify water. However, due to the strong oxidation ability of ozone, the residual ozone in water may affect the next process if it is not removed. Therefore, the residual ozone in water must be removed before entering the main process. Ultraviolet radiation with 254 nm wavelength is very effective for destroying residual ozone, which can decompose ozone into oxygen. Although different systems require different scales, generally speaking, a typical ozone removal system requires about three times as much UV radiation as a traditional sterilization system.

    In many high-tech and laboratory installations, organic matter can hinder the production of high-purity water. There are many ways to remove organic matter from water. The more common methods include activated carbon and reverse osmosis. Short wavelength ultraviolet (185 nm) can also effectively reduce the total organic carbon content. UV with shorter wavelength has more energy, so it can decompose organic matter. Although the reaction process of ultraviolet oxidation of organic matter is very complex, the main principle of ultraviolet water treatment technology is to oxidize organic matter into water and carbon dioxide by producing free hydrogen and oxygen with strong oxidation ability. Like the ozone removal system, the organic carbon degrading UV system has three to four times the UV radiation of the traditional disinfection system.

    Ultraviolet water treatment technology - degradation of residual chlorine in municipal water treatment and water supply system, chlorination disinfection is very necessary. However, in the process of industrial production, in order to avoid adverse effects on products, the removal of residual chlorine in water is often necessary pretreatment. The method includes activated carbon bed and chemical treatment. The disadvantage of activated carbon water treatment is that it needs to be regenerated continuously, and it often encounters the problem of bacteria breeding. Ultraviolet radiation at 185 nm and 254 nm wavelengths has been proved to be effective in breaking the chemical bonds of residual chlorine and ammonia chloride. Although it needs a huge amount of ultraviolet energy to work, the advantage of ultraviolet water treatment technology is that this method does not need to add any drugs to the water, does not need to store chemicals, is easy to maintain, and has the function of sterilization and removal of organic matter.
