Membrane bioreactors — UPSC Prelims PYQ 2024
“Membrane Bioreactors” are often discussed in the context of
- Assisted reproductive technologies
- Drug delivery nanotechnologies
- Vaccine production technologies
- Wastewater treatment technologies
Explanation
Option (d) is correct
- Membrane Bioreactor (MBR) is an advanced wastewater treatment technology that integrates biological treatment based on the activated sludge process with membrane filtration, such as microfiltration or ultrafiltration. In this system, microorganisms break down organic pollutants in the bioreactor, and instead of using a conventional secondary clarifier for separation, membranes are employed to retain biomass and suspended solids, thereby producing high-quality treated water.
Answer: (d) Wastewater treatment technologies: Difficulty Level: Medium
