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.
