Question

Sequentially arrange the following steps in the water treatment process: (A). Screening
(B). Filtration
(C). Sedimentation
(D). Disinfection

• A. (A), (B), (C), (D)
• B. (A), (B), (C), (D)
• C. (B), (A), (C), (D)
• D. (C), (B), (D), (A)

Hint:

Water treatment processes follow a standard order for optimal filtration and disinfection: Screening, Sedimentation, Filtration, and then Disinfection.

Answer 1

The Correct Option is A

The water treatment process follows these steps in order:
Screening: This initial stage removes large debris and suspended solids.
Sedimentation: Heavier particles are allowed to settle out at the bottom of tanks.
Filtration: Finer impurities are captured as water passes through a filter material.
Disinfection: The final treatment involves killing harmful microbes, typically with chlorine or UV radiation.
Final Answer: \[ \boxed{(A), (B), (C), (D)} \]
