The Reverse Osmosis water purifier was a device that combined multiple technologies to directly convert tap water into ultra-pure water. It mainly used the principle of reverse infiltration for water treatment. In this water purifier, the general tap water after being filtered by the membrane has a pure water conductivity of 5. m u. s/cm.(After the membrane is filtered, the water conductivity = the water conductivity × the salt removal rate. Usually, the salt removal rate of the imported reverse infiltration membrane can reach more than 99%, and it can guarantee more than 97% in 5 years of operation. If the water conductivity is higher, the second level reverse infiltration can be used. After simple treatment, the water conductivity is less than 1? s/cm), which meets the national laboratory level 3 water standard. After being filtered by the atomic level ion exchange column, the electrical resistance of the water could reach 18.2M.cm, exceeding the national laboratory level water standard (GB682 -92). The pore size of the Reverse Osmosis membrane was mostly 1 nano (1 nano = 10^ - 9m). Its separation target was dissolved ions and organic matter with a molecular weight of more than a few hundred. Its main separation target is the ions in the solution. It can effectively remove the salt in the water without chemicals. The system's salt removal rate is generally above 98%. Under a certain pressure, water molecules (H2O) can pass through the membrane, but the impurities in the source water, such as mineral salt, heavy metal ions, organic matter, colloid, bacteria, viruses, etc., cannot pass through the membrane, so that a part of the water is separated through the membrane. The water that has not passed through the membrane forms concentrated water due to the increase of solute. Each Reverse Osmosis water purifier had a Reverse Osmosis filter, and its membrane was divided into domestic and imported types. The cost of imported membranes was higher, but the filtering effect was better and more durable. For example, the Dow-Dupont membrane was recognized as a high-quality membrane material in the entire water purification industry. It was especially suitable for poor water quality in the north or for children at home. The water purifier usually had five stages of filtering. The first stage was 5um of PVP cotton (used to scale rust and impurities); the second stage was the particle activated carbon (used to absorb chemicals); the third stage was 1 um of PVP cotton or compressed activated carbon; the fourth stage was the RO membrane (key filter); the fifth stage was the post-coconut shell activated carbon filter (used to improve the taste). The first three stages of filtering were pre-treatment to provide qualified source water for the RO filter. Because the water produced by the RO filter was slow, it was usually equipped with a pressure water storage tank and a pressure switch to control the operation and stop of the machine. The price of the Reverse Osmosis membrane filter was relatively high, generally more than 1,500 yuan. Its pore size was 0.0001 um, which could effectively filter all kinds of impurities in the water, including heavy metal ions, organic matter, bacteria, viruses, and so on. The filtered water was pure water that could be directly consumed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The price of reverse infiltration water treatment equipment was affected by factors such as equipment model, processing capacity, material, process flow, and brand. The market price range was wide, ranging from thousands to tens of thousands of yuan, and high-end equipment could reach hundreds of thousands of yuan. However, it was impossible to determine the specific price of the reverse infiltration pure water equipment based on the available information. It was recommended to consider the quality, performance, after-sales service, installation and maintenance costs of the equipment, and compare different products, brands, and prices to determine the appropriate equipment price. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Ultrafilter water purifiers and Reverse Osmosis water purifiers had their own advantages and disadvantages, and they could be considered according to their own needs when choosing. Ultrafilter water purifiers were relatively cheap. The whole machine cost about 500 to 1,000 yuan. Its advantages were low cost, fast water output, and no need for electricity to operate. It could effectively remove harmful substances such as bacteria, colloid, and viruses contained in tap water. It could also filter out rust, silt, suspended matter, and a large number of particles in the water. However, the ultra-filter water purifier could not completely filter heavy metal ions. The filtered water was not pure water and could not be drunk directly. If one wanted to drink it directly, one needed to ensure that it was an ultra-filter water purifier and the water source was municipal tap water. The Reverse Osmosis water purifier was currently the most advanced water purification solution among household water purifiers. The purified water was basically pure water and could be directly consumed. It was suitable for household drinking water filtering. It could remove impurities, rust, silt, colloid, bacteria, viruses, radioactive particles harmful to the human body, organic matter, fluorescent substances, pesticides, water alkalium, and heavy metals. It ensured that the drinking water was healthy and would not have scale even if it was boiled. However, its disadvantages were that it required electricity, produced waste water, produced water slowly, and the replacement of filter elements and the treatment of concentrated water might trouble consumers. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The price range of the Reverse Osmosis Water Purifying Machine was relatively large. For example, the price of the Abik household Reverse Osmosis water purifier, drinking machine, kitchen filter, automatic scale removal, and wall-mounted water purifier was as low as 219.6 yuan after Pinduoduo superimposed coupons (no barrel price, if the budget is limited, 100G + barrel is more cost-effective); There are also about 3,000 to 5,000 yuan available for household use on the market, and there are certain differences in the price according to the amount of water produced. The price of the hot Reverse Osmosis drinking machine ranges from 1000 to 2500 yuan. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

For example, the PE filter needed to be replaced in 3 months, and the activated carbon filter needed to be replaced in 6 months. The user had to choose a suitable filter according to the water quality. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The working principle of reverse infiltration pure water treatment equipment was based on reverse infiltration technology. Water purification was mainly achieved through the following processes: 1. ** Ingress **: Water enters the equipment first. 2. ** Pretreatment **: The pre-treatment system in the equipment will remove suspended matter, dissolved matter, organic matter, etc. in the water. This step is designed to protect the subsequent membrane from damage. 3. ** Membrane Separation **: The equipment uses a reverse infiltration membrane for separation. This is the core part. There was a small pore size in the middle of the reverse infiltration membrane. Under sufficient external pressure, the semi-transparent membrane was placed between the concentrated solution (such as water with more impurities) and the diluted solution (treated water), so that the solution (water) on the concentrated solution side flowed through the semi-transparent membrane to the diluted solution side. These pores could allow water molecules to pass through and directly block most of the impurities in the water, such as bacteria, impurities, organic matter, viruses, and so on. 4. ** Pervious **: After being separated by the filter membrane, the purified water will pass through the membrane. 5. ** Waste water discharge **: The impurities blocked by the membrane and some water that did not pass through the membrane are discharged as waste water. At the same time, the equipment also used high-precision PC cotton, particle activated carbon, compressed activated carbon, and composite activated carbon for multi-stage physical filtering to ensure the quality of the water. Depending on the external pressure applied, the equipment could be divided into automatic and manual types. The difference was that the economical type required manual cleaning, while the automatic type could be cleaned by itself, but the effect was the same. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reduction of water yield of the Reverse Osmosis membrane may be caused by the following reasons: 1. ** Membrane pollution or blockage **: Suspended substances and microorganisms in the water may cause the reverse infiltration membrane to be polluted or blocked, affecting the water yield. 2. ** Insufficient water pressure **: If the water pressure does not reach the rated working pressure of the reverse infiltration membrane, the water yield will decrease. The rated working pressure can be determined by the model of the reverse infiltration membrane, and the water yield can be increased by increasing the water pressure appropriately. 3. ** Sealing of the membrane component **: When the reverse infiltration membrane is operated under conditions that greatly exceed the reference pressure, the membrane component will be sealed. At this time, the membrane component must be replaced. 4. ** Increase in the intake water conduct **: When the intake water conduct is much higher than the design value, the water yield will decrease under the same intake pressure. 5. ** Effect of substances in raw water **: The raw water contains a large number of suspended substances and dissolved substances, such as organic particles such as mineral salt, colloid, microorganisms, algae, as well as dissolved salt, indissolvable salt, metal dioxide, acid and base, etc. During the reverse infiltration process, the water flow gradually decreased, and the concentration of suspended substances and dissolved substances increased continuously. The suspended substances were deposited on the membrane to block the water channel and increase the friction resistance. When the hard-to-dissolve salt reached the saturation limit, it would form scale on the surface of the membrane, reducing the flux of the membrane, increasing the operating pressure and pressure drop, resulting in a decrease in water production. 6. ** Effect of water temperature **: The rated output of the Reverse Osmosis membrane is designed based on 25 ° C. For every 1 ° C decrease in temperature, the output will decrease by 2 - 3%. 7. ** Water production side problem **: When the pressure on the water production side is the same as the water intake pressure, the net pressure and water production will be reduced due to the pressure suppression set on the water production side or the small water production pipeline and the far transmission point. 8. ** Equipment maintenance problems **: Reverse Osmosis water treatment equipment lacks daily maintenance operations, such as inadequate maintenance of Quartz sand, activated carbon, and the filter at the front end of the softening device. If the security filter element is not replaced in time or even not replaced, it will lead to a decrease in water production. 9. ** Instrument reading error **: The pressure gauge and flow meter of the reverse infiltration water treatment equipment were not corrected before use. The inaccurate reading may affect the judgment of the reason for the reduction of water yield. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
