Landscape water treatment reverse osmosis

The principle of reverse osmosis:
We must first understand the concept of osmosis. Osmosis is a physical phenomenon. When two types of water containing different salts are separated by a semi-permeable membrane, it will be found that the salt content The water on the less side will penetrate through the membrane into the water with high salt content, but the salt content will not penetrate. In this way, the salt concentration on both sides will gradually be integrated until it is equal. However, it takes a lot of time to complete this process. For a long time, this process is also called osmotic pressure. But if you try to add a pressure on the water side with high salt content, the result can also stop the above osmosis. The pressure at this time is called osmotic pressure. If the pressure is increased Larger, it can penetrate in the opposite direction, while the salt remains. Therefore, the principle of reverse osmosis desalination is to apply a pressure greater than the natural osmotic pressure to water with salt (such as raw water), so that the osmosis proceeds in the opposite direction. , pressure the water molecules in the raw water to the other side of the membrane, turning it into clean water, thereby achieving the purpose of removing impurities and salt in the water.
The working principle of the reverse osmosis purified water machine
It is to convert raw water into After passing through a fine filter, granular activated carbon filter, compressed activated carbon filter, etc., and then pressurized by a pump, a reverse osmosis membrane (R membrane) with a pore size of /mm (equivalent to the size of E. coli /, virus /) is used. , turning higher-concentration water into low-concentration water, and at the same time isolating all impurities such as industrial pollutants, heavy metals, bacteria, viruses, etc. that are mixed into the water in large quantities, so as to meet the physical and chemical indicators and hygienic standards required for drinking, and the output is clean and pure Water is the best choice for the human body to replenish high-quality water in a timely manner. Since the water produced by R reverse osmosis technology has the highest purity among all water production technologies currently mastered by humans, with a cleanliness level of almost %, people call this product The water machine is a reverse osmosis purified water machine.
