Back to paper

Which of the following techniques can be used for reducing the total dissolved solids
(TDS) in water?
(1) Ion Exchange
(2) Distillation
(3) Carding
 

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. Both 1 and 2.

  • The ion exchange process percolates water through bead-like spherical resin materials (ion-exchange resins).
  •  Distillation is method of separating mixtures based on differences in their volatilities in a boiling liquid mixture. 
  • The main contaminant present in water is total dissolved solids (TDS) left in the water after the normal filtration process.
  • Contaminants that are larger than 2 microns are termed total dissolved solids.
