p gt;You can turn a regular two or three housing filter into a cleaning system of another, higher order by means of an ultrafiltration membrane built into a standard 10 inch housing. We recommend placing the UF membrane on the last stage of the filter after mechanical cleaning of ROSA-511 and activated carbon ROSA-541. In two-hull systems in the first place put ROSA-531. After the membrane, a post filter should be installed from the reverse osmosis systems ROSA-591, which is mounted directly on the tube using quick-release fittings. Ultrafiltration membrane ROSA-582 is made by the latest technology and is a bundle of tubes with microcracks in the walls, placed with the letter U (see photo). Contaminants remain outside the tubes, and purified water penetrates through microcracks. The tubular membrane removes foreign particles at the molecular level. Ultrafiltration purification in its effectiveness is close to reverse osmosis, but the water remains salts needed by the body. Resource up to 10,000 liters. Resource may vary depending on the quality of the source water Shelf life is not limited The date of manufacture is indicated on the package br gt; /p gt;
