Sloughing in trickling filters:
\[
\boxed{
\text{Biofilm detaches}
\rightarrow
\text{Higher suspended solids in effluent}
}
\]
Secondary clarifiers are provided to remove this detached biomass.
Increased suspended solids load to the secondary clarifier
Improved BOD removal
Reduced hydraulic loading
Show Solution
The Correct Option isB
Solution and Explanation
Step 1: Recall what a trickling filter does. A biofilm of microorganisms grows on the filter media and breaks down organic matter as wastewater trickles over it. Step 2: Understand sloughing. Over time the biofilm grows thick, and eventually chunks of it detach from the media, a process called sloughing. Step 3: Follow where the detached biomass goes. This sloughed material leaves with the filter effluent and heads to the secondary clarifier, adding to the suspended solids load it must handle. \[ \boxed{\text{Increased suspended solids load to the secondary clarifier}} \]
