Description

Technical Field

[0001] The utility model relates to the technical field of RO membrane composite water purifier filters, and specifically relates to an RO membrane composite water purifier filter. Background Technique

[0002] ‌‌The RO membrane composite water purifier filter is an efficient water treatment technology and is the core component of the reverse osmosis technology. The RO membrane composite filter uses the principle of a semi-permeable membrane. By applying pressure, water passes through the membrane in the reverse direction, thereby removing impurities and pollutants in the water. This technology is based on the osmotic pressure difference and uses a nanoscale pore size (0.0001 microns) to allow water molecules and some mineral ions to pass through, while intercepting inorganic salts, heavy metal ions, organic substances (such as pesticides, hormones), colloids, bacteria, viruses, etc., ensuring the safety and purity of the water quality. The RO membrane composite filter is widely used in water purifiers. It works together with other filters (such as PP filters, activated carbon filters, low-pressure switches, pressure barrels, etc.) to provide high-quality drinking water. The use of this filter is not only convenient but also has remarkable effects, meeting the needs of most consumers for safe drinking water. Due to its high filtration ability, the RO membrane composite filter is widely used in water purification equipment for household and commercial purposes, ensuring that people can drink safe and pure water. The RO membrane composite filter is a key component in the water purifier. Through its unique filtration mechanism, it can remove various impurities and pollutants in the water and provide safe and pure drinking water.
