Show answer & explanation
Correct answer: A
To solve this matching question, we analyze each process in List-I:
1. Ozonation (A) is a chemical process primarily used for disinfection, matching with III.
2. Aeration (B) facilitates the oxidation of dissolved metals like iron and manganese for removal, matching with I.
3. Flocculation (C) causes fine particles to clump together for easier settling, linking with IV.
4. Screening (D) physically removes large solids, matching with II.
Thus, the correct matching is A-III, B-I, C-IV, D-II.
