Often, corrosion gets a chance to develop because of 1) stagnating water or 2) unsaturated water. In both cases, the water or the oxygen dissolved in the water attacks the material of which the pipes or machines are made. This results in rust and/or pitting after a certain amount of time. Then the corrosion roughens the surface which speeds up the entire process even more. When nothing is done to counteract this process, corrosion may cause leakage, expensive emergency shut downs and replacement investments – something the Merus technology can counteract.
