Industrial wastes are treated with -before they are released in water
Answers
Explanation:
Industrial wastewater has an adverse impact on the environment. This has become a huge concern for all over the world as the wastewater released is toxic in more than one ways and affects all lifeforms dramatically. This is why safe disposal of industrial wastewater hold a huge significance for the environment. Strict adherence to industrial and government standards should be met all times to prevent and reduce water and soil pollution. This has led to invention of treatment of the industrial wastewater that will protect the ecosystem.
Industrial wastewater treatment
To reduce the effect of the wastewater released from industries on the environment, the wastewater is redirected to water treatment plant where the water is treated to remove the hazardous chemicals and released into the sewer or water sources. In recent times, the wastewater treated is reused for a variety of purposes within the industry. This minimizes the use of water from natural waterbodies.
The degree to which the wastewater is treated depends on the environmental conditions and standards in that region. If wastewater is treated to avert the deterioration of the waterbody the wastewater is released tolake, river, stream, pond or sea, stream standard is applied to treat the industrial wastewater. When the treatment is based on stream standards, the wastewater is treated for oxygen, acidity, turbidity, toxic chemicals and microorganisms. On the other hand, when the wastewater is discharged into the sewer, it is treated only for acidity, microbes, suspended solids and biochemical oxygen demand.
