Reverse osmosis membrane

Reverse osmosis membranes are artificial semipermeable membranes with specific properties that mimic biological semipermeable membranes. They are the core component of reverse osmosis technology. The principle of reverse osmosis technology is that, under the influence of an osmotic pressure exceeding that of the solution, substances cannot pass through the semipermeable membrane, thus separating these substances from water. The reverse osmosis membrane's very small pore size effectively removes dissolved salts, colloids, microorganisms, and organic matter from water. The system offers advantages such as high water quality, low energy consumption, zero pollution, simple process, and easy operation.

Working Principle

Utilizing the selective permeability of a semipermeable membrane, under pressure, only water molecules and a small amount of minerals are allowed to pass through, while the vast majority of impurities, bacteria, viruses, heavy metal ions, organic matter, and dissolved solids are effectively retained. The pore size is approximately 0.0001 microns, strictly separating the pure water that permeates through from the concentrated water that cannot.

Material Characteristics

Polyamide composite membranes are typically used. This material offers excellent chemical stability and mechanical strength, enabling long-term stable operation under a wide range of water conditions. It also boasts high salt rejection rates and excellent pollution resistance.

Performance Advantages

High-Efficiency Water Purification: Removes over 99% of impurities, including bacteria, viruses, heavy metals, and other harmful substances, ensuring water quality meets drinking standards.

Energy Saving and Environmental Protection: Modern household reverse osmosis membranes have significantly improved in energy efficiency, resulting in lower energy consumption and a progressively optimized wastewater ratio, reducing water waste.

Strong Stability: High-quality reverse osmosis membrane materials offer excellent chemical stability and mechanical strength, ensuring long-term stable operation under various water conditions and resisting damage.

Automatic Flush: Most household reverse osmosis units are equipped with an automatic flushing system that regularly rinses the reverse osmosis membrane surface to prevent contaminant deposition and extend the membrane's lifespan.
