Why is this sewage water treatment essential?

Advertisements

Solution

Importance of sewage water treatment:

  1. The sewage water contains pathogenic microorganisms like bacteria, viruses, protozoa, and parasitic worms, which can spread a variety of diseases.
  2. Also, it contains harmful chemicals that may cause toxicity if mixed with the natural resources of water. Therefore, sewage water treatment is essential before it can be discharged into natural bodies.
