Does flocculation create coagulants?

Flocculation does not create coagulants; rather, it is a separate process that occurs after coagulation. Coagulation involves the addition of chemical coagulants to water in order to destabilize and aggregate suspended particles into larger clumps called flocs. These coagulants are typically charged chemicals that help neutralize the negative charges of particles, allowing them to come together.

Flocculation follows coagulation and involves the gentle mixing of water to encourage the growth and settling of these flocs. During this stage, the flocs form from the aggregates created during coagulation; however, no new coagulants are generated during flocculation itself. Instead, flocculation enhances the effectiveness of the coagulants that have already been introduced in the previous step.

Therefore, the correct understanding is that flocculation facilitates the formation of flocs but does not create new coagulants.
