Role of Microbes in Sewage Treatment
Asked by Parvati Krishnamurthy · 2 years ago
How do microbes help in sewage treatment? Can you explain the process?
1 Answer
Microbes play a crucial role in sewage treatment by breaking down organic matter into simpler compounds. The process is typically divided into three stages:
1. Primary Treatment: Physical removal of large particles through filtration and sedimentation.
2. Secondary Treatment: Microbial degradation of organic matter. In this stage, aerobic bacteria consume organic waste and convert it into carbon dioxide, water, and energy.
3. Tertiary Treatment: Further purification to remove any remaining contaminants through chemical, physical, or biological processes.
Overall, microbes help in reducing the environmental impact of sewage by decomposing pollutants and making the water safer for discharge or reuse.
