14 Industrial Wastewater Treatment Principals and Ideas
14 Industrial Wastewater Treatment Principals and Ideas

For ,neutralization, treatment, the principle of waste treatment should be considered first. For example, acid or alkali ,wastewater, neutralizes each other or neutralizes ,acidic wastewater, with waste alkali (slag), and neutralizes ,alkaline wastewater, with waste acid. In the absence of these conditions, a neutralizing agent treatment can be ...

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

In chemistry, ,neutralization, or neutralisation (see spelling differences) 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.

Acidic wastewater, is neutralized ,with alkaline, (e.g. lime milk, sodium hydroxide solution, soda solution), ,alkaline wastewater, with acids (e.g. hydrochloric acid, sulphuric acid, carbonic acid). The use of flue gas has been developed in recent years as a particularly economical method for neutralizing ,alkaline wastewater,.
