In recent years, with the continuous popularization of household water purification products, as a member of the household product, the reverse osmosis water purifier has become a more and more popular choice for consumers because of its high filtering accuracy, good drinking taste, and reduced hardness and scale removal.
China’s vast land and resources, South and North water quality of the great difference, reverse osmosis water purifier is in the country’s complex and different conditions of raw water quality to achieve the same water standard end of the water products, manufacturers, dealers recommended products. In recent years, more and more manufacturers have also adopted reverse osmosis water purifiers as the main direction for product development. The data of Yikang in the third party shows that the reverse osmosis water purifier has increased by more than 80% in the last few years, which is much higher than that of other types of purified water products.
Reverse osmosis membrane in the core filter material of reverse osmosis water purifier is the most critical component, and it is also the core of ensuring product effluent quality. In the face of a wide variety of water purifiers on the market, how to better understand the characteristics of water purifiers of different brands and categories, which requires us to have a detailed understanding of the different specifications of RO membranes for water purifiers. The following describes the common RO membrane size and main factors affecting the RO membrane performance, so that we can have a more complete understanding of reverse osmosis products. And in the later use process, more scientific and rational use.
The size of the RO membrane
Now, RO membranes for water purifiers on the market can be divided into two major categories. One is the combination of an RO membrane and an RO membrane filter housing into one quick-connect integrated filter cartridge. The one-piece disposable filter cartridge is used. Only the RO membrane filter cartridge is used when it is used. It can be installed on the filter head. When replacing it, remove the entire filter element and replace it. Manufacturers generally customize the size of the RO membrane according to their own needs, and match with the filter shell. The second type is the more mainstream RO membrane currently on the market, there is a fixed RO membrane filter shell, and the RO membrane is screwed into the fixed RO membrane shell. This part of the RO membrane and membrane shell are relatively standardized, according to different water requirements we choose different types of RO membrane. Examples of Dow RO membranes used in brands such as Angel, Midea, Haier and Kaiyou are available, such as Dow TW30-1812-75RO, where 18 represents the diameter of the RO membrane, 1.8 inches, and 12 represents the length unit, which is 12 Inches, 75 represents the rated water production, which means that 75 gallons of water can be produced in one day, which is equivalent to 283 liters, equivalent to about 12 liters per hour.
