Question

In context of municipal solid waste treatment, match the equipment in List I with their function in List II. 

• A. P-(iii), Q-(iv), R-(i), S-(ii)
• B. P-(iii), Q-(ii), R-(iv), S-(i)
• C. P-(i), Q-(iv), R-(iii), S-(ii)
• D. P-(iv), Q-(ii), R-(i), S-(iii)

Hint:

Each piece of equipment in municipal solid waste treatment is specialized for a particular function, such as screening, size reduction, or separation of materials like metals.

Answer 1

The Correct Option is A

The correct matching between the equipment and their functions in municipal solid waste treatment is as follows: Step 1: Trommel
A trommel is used for screening, which is the process of separating materials based on their size. Therefore, \( P \) matches with (iii) Screening. Step 2: Magnetic separator
A magnetic separator is used to recover ferrous metals from the waste. Therefore, \( Q \) matches with (iv) Ferrous metal recovery. Step 3: Hammer mill
A hammer mill is a machine used for size reduction of materials, breaking them down into smaller pieces. Therefore, \( R \) matches with (i) Size reduction. Step 4: Eddy current separator
An eddy current separator is used for separating non-ferrous metals, especially aluminium, from other materials. Therefore, \( S \) matches with (ii) Aluminium separation. Final Answer: \[ \boxed{\text{(A) P-(iii), Q-(iv), R-(i), S-(ii)}} \]
