Industries use water that obtained from the water treatment system for a variety of purposes, such as
- For manufacturing goods.
- For cooling.
- For heating.
- As carrier of waste matter.
- As carrier of raw material.
- As a solvent.
The resulting water is then classified as a waste water.

Industrial waste water treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use.
The indiscriminate discharge of these waste water streams into the environment can
- Render soils "sick ".
- Pollute the receiving bodies of water.
- Cause air pollution by generating obnoxious gases.
Discharge untreated waste water into the domestic sewer system makes the task of treating domestic sewage, a very difficult and costly exercise.
To prevent any health hazards caused by discharging waste water into the environment and protect domestic sewage, the waste water must be treated before discharge.
