Reverse osmosis — the proven process

One of the most effective and reliable techniques for drinking water purification is reverse osmosis. It filters out the contaminants in water to a high degree. For example, 100% of all viruses and bacteria are eliminated.

Reverse osmosis is a purely physical process, i.e. no chemicals are added for water purification. As a consequence, this natural process is absolutely harmless for both the human body and the environment.

In this process, a semipermeable synthetic membrane is used to clean the water.

The water to be filtered is pressed at high pressure against this membrane, whose pores are so minute that only the smallest particles in the unfiltered water can pass through it, i.e. the pure water molecules. All other substances dissolved in the water accumulate in front of the membrane and are eliminated via the waste water.

Depending on the design, up to 95% of the inorganic substances such as heavy metals (lead, cadmium, mercury, etc.), mineral substances (sodium, sulphate, nitrate, etc.) are "filtered out" and organic contaminants and microorganisms (viruses, bacteria and pyrogens) are removed up to 100%. This process also occurs in living cells and is thus virtually ideal for the purification of water for human consumption.
