After approximately 1 hour, 18 percent sodium hydroxide solution is added to bring the pH to about 12, which neutralizes the acid, completes the neutralization process, and prevents the re-formation of agent. Thus, the reactor and related equipment must be able to withstand alkaline as well as acidic conditions.

Neutralization,: The addition of either an ,acid, to a base or a base to an ,acid, to produce a more nearly neutral solution. The use of alkaline or basic materials to neutralize acidity of some water is common practice in water processing. ,Neutralization, does not always mean the attaining of pH 7.0.

In this paper, through ,wastewater, acidification and c.d. altering, we clarified the pptn. process and electrochem. interaction of phosphate and coexisting ions. The removal of P is attributed to amorphous calcium phosphate (ACP) formation, whereas the removal of bicarbonate is mainly due to calcite (CaCO3) formation and ,acid,-base ,neutralization,.
