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.
