Question

Water collected from the river is made free of large pieces of dirt and pumped into reservoirs, then passed to ____________ tank, which helps in forming lumps of particles for their easy removal. (analyze)

  1. Sedimentation
  2. Distillation
  3. Filtration
  4. Flocculation

hintHint:

  • The tanks are used to make lumps of particles to remove them from water are known as flocculation tanks.

The correct answer is: Flocculation


    Flocculation
    • The river water is made free of large pieces of dirt and pumped into reservoirs, then passed to flocculation tanks, which makes lump of particles for easy removal of them.

    • First of all large wastes are removed from water in sewage water treatment.
    • Then it is passed to flocculation tanks from water reservoirs to remove impurities in the form of lumps of particles.
