Mikrofiltration, Ultrafiltration, Nanofiltration und Umkehrosmose

The REOS Compact reverse osmosis system is primarily designed for the treatment of relatively clean, pre-filtered drinking water. While it is excellent at removing impurities, pollutants and microorganisms from water to produce pure drinking water, its suitability for producing drinking water directly from a body of water such as a river depends on various factors.

For the direct treatment of river water into drinking water, preparatory steps are usually necessary to remove coarse impurities and particles before the water is passed through a reverse osmosis system. This includes pre-filtration to remove sediment, suspended solids and possible larger organic materials that could damage or clog the reverse osmosis system membranes.

Furthermore, the process of reverse osmosis can also lead to a reduced pH value, making the water slightly acidic. This is because reverse osmosis systems not only remove impurities, but also minerals that give the water flavor and contribute to pH balance. In some cases, it is therefore necessary to post-treat the osmosis-treated water to increase the pH and add minerals back in so that it meets drinking water standards and preferences.
