Reverse osmosis membranes

Membrane

— specialized membranes for reverse osmosis filtration systems carry out water purification at the molecular level – the membrane allows water molecules to pass through and retains larger contaminant molecules. The reverse is the osmotic process, in which water moves through a membrane from a solution with a higher concentration of impurities to a solution with a lower concentration. This allows contaminants to remain on one side of the membrane, allowing only clean water to pass through, ensuring the highest degree of purification. Due to regular washing, membranes have a long service life – many times longer than other filter elements, and their main disadvantage is their low productivity. It is caused not only by the slow operation of the membrane, but also by the filtration of only part of the water – about 40%, the rest of the water is drained back into the sewer.
