The mechanism behind alum's effectiveness lies in its charge-neutralizing properties. Raw water typically contains negatively charged particles, which repel each other and remain suspended. When alum is added, it breaks down into aluminum ions, which neutralize the charge of these particles. As a result, the particles can clump together to form larger aggregates, making it easier for them to settle out of the water or be caught in filter media.
