Sulfuric Acid Neutralization Sulfuric acid, is one of the most commonly produced chemicals in the world and, consequently, is the single largest source of acidity in industrial ,wastewater, streams. The ,neutralization, of ,sulfuric acid, is quite similar to any of the mineral acids, however, it is not without potential hazards.

Magnesium HydroxideNeutralization Agent of Acid Wastewater
Magnesium HydroxideNeutralization Agent of Acid Wastewater

Product feature for Neutralize acid wastewater: 1. No matter what kind of acid it neutralizes, its PH value is not more than 9. 2. Magnesium hydroxide is a relatively slow neutralizer. It will not scale even used to neutralize sulfuric acid. 3. Because of the activity and absorption ability of magnesium hydroxide, heavy metal will be absorbed during neutralization. 4.

Resource utilization of pickling wastewater (waste acid)

Neutralization is the most commonly used method to treat pickling wastewater (waste acid). The commonly used neutralizing agents are limestone, soda, sodium hydroxide, fly ash, etc. The process of lime neutralization + three effect evaporation is adopted.

GAS PROCESSING: WASTEWATER TREATMENT AND DISPOSAL:

High sulfate concentrations may result from using ,sulfuric acid, for ,neutralization, of alkalinity. Where sulfate concentrations are specifically limited, use of another ,acid,, such as hydrochloric, precipitation softening of makeup water, or use of a scale inhibitor to allow operation at higher alkalinity levels are possible approaches to resolving this problem.
