The process of adding carbon dioxide is called recarbonation and is often practiced in industrial ,wastewater neutralization,. The commonly used acids for pH adjustment of alkaline wastewaters are ,sulfuric acid, (H 2 SO 4 ), hydrochloric ,acid, (HCl), and nitric ,acid, (HNO 3 ). Among them, ,sulfuric acid, is the most widely used neutralizing agent.

Cleaner production is an important concept and an urgent need for environmental protection. Toward reducing the consumption of chemicals for swine ,wastewater, treatment by struvite crystallization, we proposed a novel combined treatment process wherein waste sulphuric ,acid, and swine ,wastewater, were treated together, with which the ,neutralization, of the waste sulphuric ,acid, solution by dolomite...

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.

The new technology will consist of two pieces of equipment: (1) Retardation facility for the recovery of sulphuric ,acid, from ,wastewater, with efficiency of 60-80% that will be reused in production. (2) ,Neutralization plant, with Nano filtration and sludge press, that would provide amount of sulphates and other hazardous substances going into environment (as ,waste water,) decrease from 9g/l to 1g/l.

The same equation relating the concentrations ,of acid, and base applies. The concept of ,neutralization, is not limited to reactions in solution. For example, the reaction of limestone with ,acid, such as ,sulfuric acid, is also a ,neutralization, reaction. [Ca,Mg]CO3(s) + H2SO4(aq) → (Ca2+, Mg2+)(aq) + …

However, the use of ,sulfuric acid, requires high safety measures. It is not only expensive to use, but also forms odorous hydrogen sulfide and mineral salts in ,wastewater, treatment. In contrast, carbon dioxide dissolves in water to form weakly acidic carbonic ,acid,, completely free from the problems posed by ,sulfuric acid,, and the ,neutralization, process is safe, harmless and efficient.
