Definition Of Freshwater Flocs

Flocculation is an aggregation process (or processes) leading to the formation of larger particles from smaller particles suspended within a natural or engineered water.23 The process usually involves some form of physical or chemical destabilization, and a step in which particles collide.23,24 For aquatic scientists, flocculation is sometimes equated with "aggregation due to polymers," whereas "aggregation due to electrolytes" is often called coagulation.25 For our purposes, both processes can be treated as similar in mechanism.23,26 From the action of either aggregation process, or from both operating together, the resultant sedimenting particle is a floc.17

The aggregating particles in the bulk water will be heterogeneous and composed of dissolved, colloidal, and particulate materials of varying size and composition27
