RO Membrane

Specification and size: ULP-4040; ULP-8040

Reverse osmosis (RO) membranes are vital components in water filtration systems, particularly in desalination and purification processes. Composed of thin, semi-permeable material, typically synthetic polymer films, they selectively allow water molecules to pass while blocking contaminants like salts, minerals, and other impurities. Operating on the principle of applying pressure to overcome osmotic pressure, RO membranes efficiently remove up to 99% of dissolved solids, providing high-quality, potable water. 

In commercial and industrial settings, reverse osmosis membranes are widely used to treat process water, wastewater, and other industrial fluids. Its versatility enables companies to optimize water treatment processes, reduce operating costs and effectively meet regulatory standards.

These membranes can be integrated into decentralized water treatment systems, such as mobile units or community facilities, to address water scarcity challenges and improve access to drinking water in untapped areas.

As the core component of reverse osmosis, reverse osmosis membrane is an artificial semipermeable membrane made by simulating biological semipermeable membrane. Usually made of polymer materials, such as cellulose acetate membrane, aromatic polyhydrazide membrane, aromatic polyamide membrane, etc. The diameter of the micropores on the surface of these membranes is generally between 0.5 and 10 nanometers, and the permeability size is closely related to the chemical structure of the membrane.

Different polymer materials have different characteristics. Some have good salt repellency, but the water penetration rate is slow; while some chemical structures contain more hydrophilic groups, so the water penetration rate is relatively fast. Therefore, an ideal reverse osmosis membrane should have an appropriate permeate volume or salt rejection rate to meet the needs of a specific application
