Water treatment is any process that improves the quality of water to
make it appropriate for a specific end-use. The end use may be drinking,
industrial water supply, irrigation, river flow maintenance, water
recreation or many other uses, including being safely returned to the
environment. Water treatment removes contaminants and undesirable
components, or reduces their concentration so that the water becomes fit
for its desired end-use. This treatment is crucial to human health and
allows humans to benefit from both drinking and irrigation use.
