D) distillation.

Question

Quizplus · Accepted Answer

Micron filtration is a water-treatment method that filters water through a screen to eliminate chemical contaminants and microorganisms. Chlorination is a method that uses chlorine to kill bacteria and viruses but does not necessarily remove chemical contaminants. Reverse filtration is a process that removes dissolved impurities like heavy metals and salts, but not necessarily microorganisms. Distillation is a process that vaporizes water and condenses it back into a liquid, leaving impurities behind, but it is not practical for large-scale water treatment. Therefore, micron filtration is the best choice for eliminating both chemical contaminants and microorganisms from water.
