Coagulation/Flocculation

Effluent coagulation/ flocculation

Coagulation and flocculation are essential processes in the physical-chemical treatment of effluents, responsible for agglutinating suspended particles and facilitating their removal.
These processes are widely used to ensure the efficient purification of water before it is discharged or reused.

Coagulation

What is it?
- Coagulation is a process that removes particles that give color and increase turbidity, as well as retaining bacterial and viral organisms.
How does it work?
- Mechanism: The colloids present in effluents are negatively charged and remain in suspension due to repulsion forces. The addition of coagulants destabilizes these colloids, allowing them to agglomerate into larger particles that can sediment.
- Process: The coagulant is added to the effluent, where it reacts chemically to form clots. This process requires efficient agitation to be effective.

Flocculation

What is it?
- Flocculation is the stage in which chemical coagulants are added to form flocs that carry away impurities. It is a physical and chemical process that aggregates small particles into larger floccules to facilitate decantation.
How does it work?
- Mechanism: The impurities are grouped by the action of the coagulant into larger flocs, which can be removed by the decantation process.
- Reagents: The coagulants commonly used are Aluminum Sulfate and Ferric Chloride.
