Coagulation and Flocculation - Mrwa
Coagulant chemicals with charges opposite those of the suspended solids are added to the water to neutralize the negative charges on non-settlable solids (such as clay and color-producing organic substances). Once the charge is neutralized, the small suspended particles are capable of sticking together.

Activity Models - Teaching Phase Equilibria
Interactions between elements in different crystallographic sites of minerals affect the energetics of the system, and so affect the ability of the components to react in the system. Consequently, in solutions (solid, liquid or gas) as the composition changes, activities may deviate significantly from ideality. This is called non-ideal mixing.
