pH Adjustment and Neutralization the basics
pH Adjustment and Neutralization the basics

In the case of an acid neutralization, caustic (NaOH) is added to the effluent stream to pH Neutralize the solution. This neutralization, or titration can be expressed as follows: HCl + NaOH → NaCl + H 2 O. In the example shown above hydrochloric acid (HCl) is neutralized with caustic (NaOH) and yields ordinary table salt (NaCl) and neutral water.

Acid Waste Neutralization - AQUAMAG®

Acid Waste Neutralization. AQUAMAG ® and MAGOX ® are two of the most effective reagents available for the neutralization of acid waste streams such as hydrochloric acid (HCl) and sulfuric acid (H 2 SO 4) in a variety of applications. Because of their high alkalinity, much lower volumes of product is needed over more traditional reagents to achieve ...

Neutralization (chemistry) - Wikipedia
Neutralization (chemistry) - Wikipedia

In chemistry, neutralization or neutralisation is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution. The pH of the neutralized solution depends on the acid strength of the reactants.

In summary, the challenge here is to use an acidic material that is powerful enough to neutralize the alkalinity in the wastewater fairly efficiently and effectively, but not have the capability to dangerously lower the pH. Based on my experience, carbon dioxide is the best to meet this criteria, but is likely cost prohibitive in your application.
