Dosing Guidelines
For pH adjustment: meter carefully to target pH. Available in 30-50% solutions. Highly exothermic — add to water with mixing.
How It Works
Strong alkali that rapidly neutralizes acids, precipitates heavy metals (zinc, copper) as insoluble hydroxides, and raises pH for optimal coagulation.
Usage Tips
Caustic soda — highly corrosive. Store in stainless steel or HDPE. Use appropriate PPE. Quick pH response makes it ideal for automated dosing.
