Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to a reverse osmosis water treatment device. Background Art

[0002] Among existing technologies, reverse osmosis (RO) has been one of the most widely used and rapidly developing purification technologies in recent years in the field of pure water purification. Domestic RO applications include large-scale boiler feed water, various industrial pure waters, and drinking water. Beyond this, it is also widely used in the semiconductor electronics, pharmaceutical, alcoholic beverage, chemical, and environmental protection industries. Since its introduction in the mid-20th century, RO technology, as the most sophisticated separation technology, can reject all dissolved salts and organic matter with a molecular weight greater than 100. However, RO technology still has certain limitations. While maintaining high desalination rates, it is difficult to further improve the recovery rate of the RO system. This is related to the performance of the RO membrane and the size of the system. Generally, the larger the system's water output, the higher the overall recovery rate. However, some water applications do not require excessive water output, so the recovery rate for systems with small water outputs is generally between 60% and 65%. Recycling a portion of the concentrated water is often used to increase the recycle rate, but this method currently struggles to achieve a stable increase in the recycle rate. Secondly, reverse osmosis membranes are often damaged by incomplete treatment of impurities and scale in the water, which greatly increases the cost of pure water preparation and causes a decrease in desalination rate.
