Which term describes the small clumps formed during coagulation that settle in sedimentation?

• A. Microflocs
• B. Macroflocs
• C. Colloids
• D. Sediments

Answer: (A)

In water treatment, the small clumps formed during coagulation are called microflocs. Coagulation neutralizes the charges on suspended particles, allowing them to come together into tiny clusters. These initial clusters are microflocs, which are still fairly small. As mixing continues in the subsequent stage, these microflocs collide and stick together to form larger clumps called macroflocs. The larger flocs then settle more readily in the sedimentation basin, which is why sedimentation targets the floc that has grown from those initial microflocs. Colloids refer to the individual fine particles before coagulation, and sediments are the settled material collected after sedimentation, not the small clusters formed during coagulation.
