Waste water is the water that is contaminated by commercial as well as domestic processes. The water largely contains food waste, human waste and chemicals. Industries like manufacturing and mining and domestic activities like washing, bathing, etc, contaminate the water to a great extent.
In the developing countries, this wastewater is discharged in the environment sans any treatment. In some countries, primary treatment of the wastewater is carried out before discharging it. This wastewater takes a toll on the environment. It contaminates the overall environment.
Importance of wastewater treatment
This makes it very essential to keep the water clean. To protect the environment and also, to arrest the loss of water from our planet, it is very important to treat the wastewater. The water can be treated by wastewater treatment to remove the physical, chemical and the biological contaminating factors.
