What is pH Adjustment and how pH Neutralization System works?

Acids are used to neutralize bases, and vice versa. The pH adjustment process can be performed in either a batch or continuous flow treatment. Depending on the application, the more data that can be gathered on the expected waste flow, temperatures, and waste stream constituents, the better the system will operate.
