WebThe process of flocculation and sedimentation is a dynamic and nonlinear process of aggregation, breakage, reaggregation and rebreakage. It can also be seen from Figure 2 that aggregation takes place as a result of particle-particle, particle-microflocs, or microflocs-microflocs collisions, leading to the formation of macroflocs. WebAug 5, 2024 · Let’s consider a few scenarios where flocculant selection can make a difference. 1. Feeds needing high solids dilution prior to flocculation. Fine particle flocculation leads to fractal-like aggregate structures, meaning that when they are large, they are highly porous and fragile. Large, fast-settling sizes often requires solids dilution ...
