Swiss Alps Calcium Removal
Limescale, the cristalized mineral deposits often found in sewer pipelines of hard water areas, has been succesfully removed from multiple sewer pipelines in the Swiss Alps by H.Jakober with the Sewer Robotics water jet system.
The calcium carbonate had build up over many years and was so hard that it required up to 2500bar (36,250psi) to remove at some sites.
