Neutralisation :, too, acid or, too, alkaline wastewater flows are neutralized until a pH value of approx 7 is reached. The main reason to neutralize wastewater is to prepare it for further treatment in a biological wastewater treatment station or to meet the standards for discharge (eg. too acid wastewater can damage the sewer system and wastewater treatment plants).

A Lower-cost Approach to Treating Low-volume Refinery ...

Acid springing is probably one of the oldest on-site treatment methods used in refineries to dispose of spent caustic. Acid springing works by adding a strong acid (e.g., sulfuric acid) to the spent caustic until the pH is around 3. At this low pH, the acid oil tends to dissociate from the aqueous phase to form a separate floating “oil” layer.
