- Coagulant Selection: The choice of coagulant is tailored to the specific contaminants present in the water. Factors such as water chemistry, contaminant type, and desired treatment outcome influence coagulant selection.
1.2 Sedimentation:
- Gravity-Driven Separation: The heavier flocs, now significantly larger than their original particle forms, readily settle to the bottom of the treatment vessel due to gravity.
- Clarified Water Collection: The clarified water, free of suspended solids, is then collected from the top of the vessel.
- Sludge Removal: The settled sludge, containing the aggregated contaminants, is periodically removed from the vessel for further treatment or disposal.
1.3 Advantages of High-Rate Coagulation and Sedimentation:
- Rapid Treatment: The combination of high-rate coagulation and efficient sedimentation allows for swift removal of contaminants, ensuring rapid water purification.
