Question

which process is used to remove larger objects from water during purification? screening chlorination sedimentation filtration

Explanation:

• Screening: This process uses physical barriers (like screens) to remove larger objects (such as debris, twigs) from water.
• Chlorination: It is a disinfection process (using chlorine) to kill harmful microorganisms, not for removing large - sized physical objects.
• Sedimentation: Involves the settling of heavier particles (due to gravity) but these are usually smaller suspended solids compared to what screening removes.
• Filtration: Passes water through a porous medium (like sand, activated carbon) to remove smaller suspended particles, dissolved impurities (to some extent), not large objects.

Answer:

Screening
