RO reverse osmosis membrane is a high-precision core component of water treatment technology. It uses the principle of semi-permeable membrane and can effectively intercept impurities such as dissolved solids, bacteria, viruses, heavy metal ions, etc. in water under pressure, allowing only water molecules to pass through, thereby producing high-quality pure water. This technology is widely used in household water purifiers, commercial water purification systems, and industrial water treatment fields, such as water purification in the pharmaceutical, chemical, and power industries, providing a solid guarantee for people's drinking water safety and industrial water quality.
