प्रश्न

What would happen if oxygen availability to activated sludge flocs is reduced?

पर्याय

  • It will slow down the rate of degradation of organic matter.

  • The center of flocs will become anoxic, which would cause death of bacteria and eventually breakage of flocs.

  • Flocs would increase in size as anaerobic bacteria would grow around flocs.

  • Protozoa would grow in large numbers.
