Microbes in Sewage Treatment

Microbes play a crucial role in sewage treatment:

1. Primary treatment: Physical removal of large particles
2. Secondary treatment: Biological treatment using microbes
   • Aerobic bacteria break down organic matter
   • Anaerobic bacteria further decompose sludge
3. Tertiary treatment: Removal of specific pollutants

Microorganisms like Pseudomonas, Nitrosomonas, and methanogens are involved in different stages of sewage treatment, helping to clean water and reduce environmental pollution.
