Techniques
Chapter 1: Techniques
Understanding Purac in Water Treatment
Purac, as discussed, is a general term for polyacrylic acid (PAA) polymers, particularly their sodium salts. These polymers are primarily employed as flocculants and coagulants in water treatment processes. They work by:
- Coagulation: Neutralizing the charges of suspended particles in water, causing them to clump together (aggregate).
- Flocculation: Binding the aggregates together into larger, heavier flocs that settle out of the water more easily.
Key Techniques using Purac:
- Dosage and Mixing: The amount of Purac used and how it is mixed with the water are crucial factors determining the effectiveness of the treatment.
- Sedimentation: After flocculation, the heavy flocs settle to the bottom of the water, allowing for their removal.
- Filtration: Water is passed through a filter to remove any remaining solids, enhancing clarity and ensuring proper treatment.
- Dehydration: In sludge treatment, Purac aids in removing water, reducing sludge volume and disposal costs.
Advantages of Purac-based techniques:
- High efficiency: Purac solutions are known for their ability to effectively remove a wide range of contaminants.
