Why are flocs important in biological treatments of waste water ?

Explanation

### Step-by-Step Solution:

1. **Understanding Flocs**: Flocs are aggregates or clumps of microorganisms, particularly bacteria, that are often found in wastewater treatment systems. They can also include fungal filaments, which help to form a mesh-like structure.

2. **Role in Wastewater Treatment**: The primary function of flocs in biological treatment is to facilitate the breakdown of organic matter present in wastewater. This is crucial for reducing the pollution load before the water is released back into the environment.

3. **Digestion of Organic Matter**: The bacteria within the flocs actively digest organic materials, breaking them down into simpler substances. This process is essential for the removal of biodegradable waste from the water.
