Purely reverse osmosis membranes are an artificial membrane comprising part of the membrane, which is selectively permeable in only one direction , like biological membranes. They are the main constituent of the osmosis technique . The science behind osmosis is that over a semi-permeable membrane, other materials are unable to cross through it in a vacuum that is more powerful than the solution’s vacuum pressure: these additional substances and water are then dumped.

Applications    

Mainly used in reverse osmosis pre-treatment, drinking water treatment, water reuse, etc.    

Filtration media    

Suspended matter, colloids, proteins and microorganisms and other molecular substances in solution.    

Working Principles

Reverse osmosis is the process of applying a pressure greater than the osmotic pressure of the solution on the concentrated solution side, forcing the water molecules to pass through the semi-permeable membrane into the dilute solution in the reverse direction (opposite to the natural direction of osmosis), as in the reverse osmosis process, the water molecules on the concentrated solution side flow through the semi-permeable membrane into the dilute solution, while the vast majority of the solutes (dissolved solids) cannot pass through the membrane and are retained. Therefore, the concentrated solution is further concentrated, or dehydrated, and the dilute solution is diluted and purified, or desalinated.

Product Advantages

Membrane element,Filtration accuracy up to 0.0001 micron, filtered by RO membrane, strongly filtered out bacteria impurities, heavy metals and other harmful substances.

Reverse osmosis membrane has good water quality, low energy consumption, no pollution, simple operation, etc., widely used in wastewater reuse and material concentration and other fields.

Stable

Good stability: High mechanical strength and longevity, able to function at low operating pressures.

Less influenced by factors such as pH and temperature and able to function at low operating pressures.

High precision filtration accuracy of 0.0001 microns:

Reverse osmosis membranes are the finest membrane separation products, retaining all dissolved salts and organic matter with a molecular weight greater than 100, while allowing water molecules to pass through.

Ease of use of the equipment:

Modular design, easy to install, reduces water and effluent usage costs, can be integrated with existing membrane filtration systems or ion exchange systems to achieve up to 80% rinse water circulation.

Our membranes are meticulously engineered to replicate the natural selectivity of biological membranes, allowing for precise filtration in only one direction. As a key component of the osmosis technique, these membranes play a crucial role in purifying water and separating contaminants.

The science behind osmosis is elegantly applied in our membranes. By leveraging semi-permeable properties, substances other than water are unable to pass through the membrane under vacuum pressure, ensuring that only pure water is retained while impurities are effectively removed.
