FAQs on Microbes in Sewage Treatment Video Lecture - NEET

1. What are microbes in sewage treatment?
Ans. Microbes in sewage treatment refer to the microscopic organisms, such as bacteria, viruses, and fungi, that play a crucial role in the breakdown and removal of organic matter in wastewater. These microbes are responsible for the biological processes involved in sewage treatment.
2. How do microbes contribute to sewage treatment?
Ans. Microbes contribute to sewage treatment by breaking down organic matter present in wastewater. Bacteria, for example, play a vital role in the decomposition of organic compounds, converting them into simpler substances. This process helps in reducing the biochemical oxygen demand (BOD) and removing harmful pollutants from the sewage.
3. Which specific microbes are commonly used in sewage treatment plants?
Ans. Several specific microbes are commonly used in sewage treatment plants. Some of the commonly used bacteria include facultative bacteria, aerobic bacteria, and anaerobic bacteria. These bacteria help in the decomposition of organic matter and the removal of nutrients from the wastewater. Additionally, certain viruses and fungi also contribute to sewage treatment processes.
4. What is the significance of microbes in sewage treatment?
Ans. Microbes play a significant role in sewage treatment due to their ability to break down organic matter and remove pollutants from wastewater. Without the presence of microbes, the decomposition process in sewage treatment plants would be slow, leading to the accumulation of harmful substances and an inefficient treatment process. Therefore, microbes are crucial for the effective functioning of sewage treatment plants.
5. Can sewage treatment plants function without microbes?
Ans. No, sewage treatment plants cannot function effectively without microbes. Microbes are essential for the biological processes involved in sewage treatment, such as the decomposition of organic matter and the removal of pollutants. Without the presence of microbes, the treatment process would be inefficient, leading to the accumulation of harmful substances in the treated water. Therefore, the presence of microbes is vital for the proper functioning of sewage treatment plants.
