Water Treatment at a glance

Water is a precious resource and should be used wisely. Water treatment consists of various mechanical and chemical processes that aim to remove contaminants from the water or reduce their concentration to make the water more acceptable for its intended end use.

Water treatment technologies are used to produce water for human consumption and industrial purposes. They are responsible for preventing corrosion, flaking, and bacterial growth. They can also be applied to treat wastewater for reuse or prior to discharge into the environment.
