Q99. "Membrane Bioreactors" are often discussed in the context of:
Detailed Solution
Membrane Bioreactors (MBRs) represent an advanced wastewater treatment technology that combines a conventional activated sludge process with membrane filtration. The membranes, typically ultrafiltration or microfiltration, separate solids from the treated water, producing a high-quality effluent.
MBRs are highly effective in removing pollutants, bacteria, and suspended solids from municipal and industrial wastewater, making them a crucial component in modern water purification and reuse systems. The other options relate to different fields of biotechnology and medicine and are not the primary context for Membrane Bioreactors.
This question tests knowledge of environmental technologies, particularly in pollution control and water management, which is a significant part of the Environment & Ecology syllabus and often appears in current affairs.
