As environmental protection problems become increasingly serious, people pay more and more attention to health. In terms of drinking water, they generally buy water purifiers to drink healthy purified water. There are two working principles of water purifiers on the market, one is reverse osmosis and the other is ultrafiltration. So, which one is better? The following is a detailed introduction, let’s take a look together. As environmental protection problems become increasingly serious, people pay more and more attention to health. In terms of drinking water, they generally buy water purifiers to drink healthy purified water. There are two working principles of water purifiers on the market, one is reverse osmosis and the other is ultrafiltration. So, which one is better? The following is a detailed introduction, let’s take a look together. First, let’s look at the introduction to the difference between reverse osmosis and ultrafiltration. (1) The effluent water quality is different from the testing standards of the health department. To give you an example, the effluent bacterial indicator, the ultrafiltration water purifier follows the "general water quality processor", the total number of colonies is 100/ml; but in contrast Osmotic water treatment equipment is 20/ml, which has stricter requirements. Of course, the water quality of reverse osmosis water treatment equipment should also be much better than that of ultrafiltration water purifiers. (2) Reverse osmosis water treatment equipment provides water for quality separation, pure water is provided for drinking, and concentrated water is used for washing; ultrafiltration water purifiers are usually used for washing water; when the tap water quality is relatively high, it can also be used as ultrafiltration drinking water. Pure water equipment. Let’s look at the introduction of the advantages and disadvantages of the two. (1) The advantages of ultrafiltration water purifiers are: usually no pumps, no power consumption, no electrical safety issues; fewer joints, low water pressure, relatively low failure rate and water leakage probability; simple structure and affordable price; its disadvantages are : It is not effective in removing chemical pollutants in water; it is not effective in water supply emergencies; the taste of water is not good; it cannot reduce the hardness of water. If the hardness of tap water is high, the water boiling container may be scaled. Ultrafiltration membranes can remove macromolecules, colloids, proteins, particles, etc. in solutions. They have the characteristics of low operating pressure, large water production, and easy operation. By testing the purification effect of the hollow fiber ultrafiltration membrane device to deeply purify the raw water for wine production, it is shown that the ultrafiltration membrane water purification device can effectively eliminate secondary pollution of water in the pipe network and further improve water quality. (2) The advantages of reverse osmosis water treatment equipment are: safe water quality, can effectively remove various harmful impurities in water quality; strong effect on water supply emergencies; good water taste; can effectively reduce the hardness of water quality, boiling water container It is not easy to scale; its disadvantages are: it uses a pump, consumes electricity, and has electrical safety issues; it has many joints, high water pressure, and a relatively high failure rate and leakage probability; its structure is relatively complex and the price is expensive. In short, reverse osmosis and ultrafiltration are both methods of purifying water. Due to their different working principles, their effects and wide range of applications are also different. So, which one of the two is better? We can’t decide, it still depends on the actual water quality and the actual needs of the buyer. What we have to do before buying is to understand the advantages and disadvantages of the two, and choose a better one based on our own needs. Whatever suits you is fine.
