Question

In the secondary treatment of STP, the masses of bacteria associated with fungal filaments are called ______________.

• A. mycelium
• B. flakes
• C. flocs
• D. hyphae

Hint:

Flocs settle down during secondary treatment, helping in sludge formation.

Answer 1

The Correct Option is C

Step 1: Understanding secondary treatment.
Secondary treatment of sewage involves biological oxidation of organic matter using microorganisms.
Step 2: Formation of flocs.
Bacteria form aggregates with fungal filaments, creating mesh-like structures.
Step 3: Identification of correct term.
These aggregates of bacteria and fungi are called flocs, which help in efficient decomposition of organic matter.
Step 4: Conclusion.
Hence, the masses are known as flocs.
