    1. Settling and Floatation – Part 2

    2. FLOCCULENT SETTLING (1) Particles settling in a water column may have affinity toward each other and coalesce to form flocs or aggregates. These larger flocs will now have more weight and settle faster overtaking the smaller ones, thereby, coalescing and growing still further into much larger aggregates. The small particle that starts at the surface will end up as a large particle when it hits the bottom. The velocity of the growing flocc will therefore not be terminal (constant or one, but changes as the size changes. Because the particles form into flocs, this type of settling is called flocculent settling or type 2 settling.
