Characterization of acid mine water by acidity helps us explore possibilities for recovering by-products with economic value and choosing the most suitable and efficient treatment system possible. This is because characterization by acidity allows us to ascertain not only protonic acidity, but also mineral acidity, which is generally overlooked by typical characterization methods.

Designing phased acid water treatment systems with acidity content in mind enables better resource usage in that less lime is required in the neutralization process. It also enables the recovery of metals from the sludges generated. This makes the treatment of acid water cheaper and more efficient and allows for better environmental control.
