Wastewater must be neutralized to adjust its pH value in order to meet the requirements of different processing units within a wastewater treatment system. Neutralization may be used to treat acid wastewaters containing metals. Adding an alkaline reagent increases the pH of the acid waste. This forms a precipitate that collects unwanted metals.

Neutralization is the process of adjusting the pH of water through the addition of an acid or a base, depending on the target pH and process requirements. Most part of the effluents can be neutralized at a pH of 6 to 9 prior to discharge. In chemical industrial treatment, neutralization of excess alkalinity or acidity is often required.
