What is reverse osmosis equipment?

<p>What is <a href="https://www.onelynn.net/" target="_blank">reverse osmosis equipment</a>?</p><p><br></p><p><a href="https://www.onelynn.net/" rel="noopener noreferrer" target="_blank"><strong>Reverse osmosis equipment</strong></a> is a membrane separation technology that uses pressure as the driving force by means of the function of selective permeable (semi-permeable) membranes. When the pressure applied in the system is greater than the osmotic pressure of the influent solution, water molecules continuously permeate The membrane flows into the central pipe through the water production channel, and then flows out of impurities in the water at one end, such as ions, organic matter, bacteria, viruses, etc., which are trapped on the inlet side of the membrane, and then flow out at the outlet end of the concentrated water to achieve the purpose of separation and purification. . The following is about its operation methods and common problems and solutions, the editor of reverse osmosis equipment has done some sorting, for your reference.</p><p><br></p><p>The reverse osmosis equipment is to pass the raw water through a fine filter, granular activated carbon filter, compressed activated carbon filter, etc., and then pressurize by a pump, using a pore size of 1/10000μm (equivalent to 1/6000 the size of E. /300) reverse osmosis membrane (RO membrane), which turns high-concentration water into low-concentration water, and at the same time isolates all the impurities mixed into the water such as industrial pollutants, heavy metals, bacteria, and viruses, so as to achieve the physical and chemical requirements for drinking Indicators and hygienic standards, producing pure to pure water, which is a good choice for the human body to replenish water in time. Because the purity of water produced by RO reverse osmosis technology is the highest among all water production technologies currently mastered by humans, the cleanliness is almost 100 %, so people call this water production machine a reverse osmosis pure water machine.</p><p><br></p><p><br></p><p>Reverse osmosis is a modern new type of pure water treatment technology. Through reverse osmosis element to improve the purity of water quality, remove impurities and salt contained in the water. The purified water we drink daily is treated by reverse osmosis equipment, and the water quality is clear.</p><p><br></p><p>It is the United States that uses reverse osmosis technology, which invented membrane separation technology powered by power difference. With the promotion of this technology, my country began to use reverse osmosis technology. The pure water equipment on the market adopts reverse osmosis membrane treatment technology, and has undergone certain improvements and design innovations in our country. The technology is very mature.</p><p><br></p><p>A reverse osmosis membrane is designed in the reverse osmosis purified water equipment. The pressure on both sides of the membrane is different. The pressure on both sides is used as the driving force to force the raw water to pass through the reverse osmosis membrane. The low salt concentration will permeate to the high concentration salt direction. The equilibrium state that can be achieved is the osmotic pressure of the liquid. When the pressure on one side of the salt water contained is opposite to the osmotic pressure on the other side, the flow in the opposite direction will occur, resulting in a reverse osmosis process.</p><p><br></p><p>Reverse osmosis purified water equipment adopts this technology and adopts intelligent control of automatic water supply and water cutoff. This is pure water equipment.</p><p><br></p><p>① If there is residual gas in the reverse osmosis equipment, it should be clear or change the filter to ensure that the pipeline is not leaking, that is, it should be carried out slowly when there are no bubbles in the flowmeter. , If bubbles are found during the pressure increase process, the pressure should be gradually reduced to check the cause.</p><p><br></p><p>②The shutdown is inaccurate. The first thing is to quickly reduce the pressure when shutting down, but the over-the-top washing is not implemented. Since the concentration of inorganic salts on the concentrated water side of the membrane is higher than that of the raw water, if the over-the-top washing is not implemented, the membrane will be fouled and sent. The membrane becomes stained; it is not possible to use the pre-treatment water with chemical reagents for washing, otherwise the membrane will become stained when the chemical materials are sent to the membrane during the shutdown period.</p><p><br></p><p>③The reverse osmosis membrane has poor residual chlorine resistance. If there is no accurate addition of chlorine and other disinfectants in the use, it will cause microbial contamination.</p><p><br></p><p>④ If the residual chlorine in the reverse osmosis equipment is not well surveyed, the residual chlorine will be sent to the membrane and become damaged.</p><p><br></p><p>⑤ Failure to wash in real time or inaccurate washing method can also cause signs of damage to the membrane delineation function.</p><p><br></p><p>In order to ensure the useful life of reverse osmosis equipment, strict compliance with the control method is required to ensure the integrity of the membrane function. If the membrane is contaminated, it needs to be cleaned and disinfected immediately.</p>
