Bulking of activated sludge is due to the presence of filament micro-organism, e.g. fungi . Chlorination is some times used to destroy such organisms to avoid bulking of activated sludge.

Explanation:

Sewage treatment is a process of removing contaminants from wastewater, primarily from household sewage. The process involves physical, biological, and chemical processes to remove the contaminants and make the water safe to discharge into the environment. Chlorine is one of the commonly used chemicals in sewage treatment plants.

Chlorine is used in sewage treatment to avoid bulking of activated sludge. Activated sludge is a biological process that involves microorganisms that consume organic matter in the sewage. The microorganisms form flocs or clumps, which then settle down to the bottom of the tank, leaving the treated water on top.

However, sometimes the flocs become too large and do not settle down effectively, causing bulking. Bulking leads to poor settling, which can result in a decrease in the efficiency of the treatment process. Chlorine is added to the sewage to decrease the bulking caused by filamentous bacteria.

When chlorine is added to the sewage, it oxidizes the filamentous bacteria, causing them to break down and become less viscous. This, in turn, allows the flocs to settle down effectively, leading to a more efficient treatment process.

Therefore, the correct answer is option C, to avoid bulking of activated sludge.
