01.RO reverse osmosis water purifier features and core components

In recent years, RO reverse osmosis water purifiers have been highly regarded for their excellent filtration performance, which effectively reduces water hardness, removes scale and residual chlorine, and provides users with a pure drinking water experience. It can efficiently reduce water hardness, completely remove scale, while eliminating residual chlorine to ensure the taste of pure drinking water. These features make RO reverse osmosis water purifier become more and more consumers in pursuit of healthy drinking water of choice.

When it comes to RO reverse osmosis water purifier, its core component - RO reverse osmosis membrane, is undoubtedly the key to protect the quality of water.RO membrane is composed of high-quality materials, such as imported food-grade cartridges, to ensure that the water is pure and safe, to avoid secondary pollution. The membrane is carefully composed of cross-linked aromatic polyamide (desalination layer), polysulfone (loose support layer), and polyester non-woven fabric (base layer). In terms of product materials, it is crucial to choose high-quality cartridge materials, as inferior materials may lead to secondary contamination. In contrast, the quality of RO reverse osmosis membranes with imported food-grade cartridges, such as the Franny brand, is more trustworthy.

 

02.Filtration Principle and Function

▣ RO Membrane Filtration Principle

During natural osmosis, water molecules will diffuse from the area of low concentration to the area of high concentration until the concentration balance is reached. However, RO reverse osmosis technology realizes the flow of water molecules from high concentration to low concentration by applying external force (i.e., overcoming osmotic pressure) to achieve efficient water purification. This process is usually carried out with the help of a high-pressure water pump to provide the required external force.


▣ Core Functions of RO Membranes

The pore size of RO membranes is so tiny that it is only one-hundred-thousandth of the diameter of a hair strand, or 0.0001 microns. This fine pore size design makes it impossible for microorganisms such as bacteria and viruses to pass through, thus ensuring the high purity of the effluent water. 000 times the difference in pore size. This allows only water molecules and a very small number of ions to pass through, thus ensuring excellent filtration. ro membrane can remove a variety of dissolved components and microorganisms, and its desalination rate is as high as 98%-99.8%, to ensure that the water quality of pure and safe.

 

03 RO membrane common misunderstanding analysis
▣ The effect of RO membrane on TDS value

Although RO reverse osmosis water purifier has been widely popularized in China, but many users still have many misunderstandings about the understanding and application of RO membrane. One of them is the misconception that after the RO membrane filtered water, its TDS value should be 0. In fact, the desalination rate of the RO membrane and the quality of raw water affects the TDS value, the national drinking water standards to ensure health. The key factors affecting the TDS value of RO membrane effluent include the performance parameters of the RO membrane, especially its desalination rate, and the quality of raw water.

▣ RO membrane wastewater problems and optimization

Myth 2 believes that RO reverse osmosis membranes produce a large amount of wastewater during water production, resulting in a waste of water resources. And when making water, in order to keep the reverse osmosis membrane clean and smooth, the machine will discharge a certain amount of concentrated water for flushing. Although the RO membrane water production process produces wastewater, it is optimized to have a low wastewater ratio and can be reused without waste. This flushing is necessary to ensure the proper functioning of the RO membrane. Although wastewater is present, the RO membrane has been technically optimized to reduce the wastewater ratio to a low level.

▣ The Importance of the Pre-Filter Cartridge

Myth 3 The quality of the pre-filter cartridge is thought to have little effect on the RO membrane. In fact, RO membrane has clear requirements for the quality of incoming water, regardless of brand. The quality of the pre-filter element has a significant impact on the life of the RO membrane, need to ensure that the residual chlorine content is less than 0.05mg / L to maintain the stability of the RO membrane work. If the use of poor quality pre-filter cartridge, will significantly shorten the service life of RO membrane. At present, the household RO membrane usually requires the residual chlorine content in the feed water to be controlled at a low level.

After the above discussion, I believe you have a better understanding of RO membrane, and now you can better enjoy the pure drinking water experience brought by RO reverse osmosis water purifier.
