Water treatment at a glance
Water is a precious resource and needs to be used wisely. Water treatment consists of several mechanical and chemical processes that aim to remove water contaminants or reduce their concentration in order to make water more acceptable for a desired end-use.
Water treatment technologies are used to produce water intended for drinking and industrial purposes. They are responsible for preventing corrosion, scaling and bacterial development. They can also be applied to treat wastewater for reuse or prior to its discharge in the environment.
Air Liquide supplies a range of products, equipment and services for water and wastewater treatment. We supply oxygen and carbon dioxide for common wastewater operational needs such as biochemical oxygen demand (BOD) and pH reduction as well as volatile organic compound (VOC) and odor control.
