What does the term 'Zeta Potential' refer to?

The term 'Zeta Potential' refers specifically to the difference in electrical charge around a particle. This concept is crucial in colloidal chemistry and plays a significant role in the stability of colloidal dispersions. Zeta potential is a measure of the electrostatic repulsion between charged particles in a fluid, which influences their tendency to aggregate. When the zeta potential is high, it indicates that particles repel each other strongly, helping to maintain a stable suspension. Conversely, a low zeta potential can lead to particle aggregation and destabilization.

In water treatment processes, understanding zeta potential is vital for effective coagulation and flocculation, as operators use this knowledge to control the removal of suspended solids and enhance water clarity. By measuring and adjusting zeta potential, operators can optimize the performance of treatment chemicals and achieve better water quality outcomes.
