Exercise Correction
**Explanation:** GFC is a suitable solution for high turbidity because it effectively removes suspended solids, which contribute to turbidity. Its ability to attract and neutralize negatively charged impurities, causing them to aggregate and settle out, makes it ideal for this purpose. **Steps involved in using GFC for turbidity removal:** 1. **Dosage:** The appropriate amount of GFC is added to the water based on the level of turbidity and other water characteristics. 2. **Mixing:** The GFC is thoroughly mixed with the water to ensure uniform distribution and optimal coagulation. 3. **Flocculation:** The GFC promotes the formation of larger particles called flocs, which contain the suspended solids. 4. **Sedimentation:** The flocs settle to the bottom of the treatment tank due to their increased weight. 5. **Filtration:** The remaining suspended solids are removed by passing the water through filters. **Benefits of using USFilter/General Filter GFC:** * **High-quality products:** USFilter/General Filter offers various GFC grades, ensuring optimal performance for turbidity removal. * **Technical expertise:** Their expert team can guide the municipality on proper dosage, mixing, and other factors for effective treatment. * **Reliable supply chain:** Consistent GFC availability ensures uninterrupted water treatment operations.

Techniques
Chapter 1: Techniques
GFC: A Powerful Tool in Environmental & Water Treatment: Understanding USFilter/General Filter's Role
1.1 Coagulation and Flocculation
GFC's primary mechanism of action involves **coagulation** and **flocculation**, which are key processes in water treatment. These processes aim to remove suspended solids and other impurities by promoting their aggregation and settling.
- Coagulation: This step involves adding GFC to the water, which undergoes hydrolysis, forming positively charged ferric hydroxide ions. These ions neutralize negatively charged impurities, causing them to destabilize and start clumping together.
- Flocculation: In this step, gentle mixing is used to encourage the small, destabilized particles to collide and form larger, heavier flocs. These flocs are easier to remove through sedimentation or filtration.
1.2 Chemical Dosing and Control
Precise dosing of GFC is crucial to ensure optimal treatment. This involves:
- Determining the appropriate GFC dosage: This depends on various factors, including the water quality, desired treatment level, and the specific GFC product used.
- Monitoring and adjusting the dosage: Regular monitoring of water quality parameters and GFC dosing is essential for maintaining treatment efficiency and avoiding overdosing.
1.3 Sedimentation and Filtration
After coagulation and flocculation, the formed flocs are removed through:
