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. The result is an incoming solution of which the pH …
