Sodium Hydroxide (Caustic Soda) pH Adjuster

Sodium hydroxide is the primary alkaline pH adjustment chemical used in water and wastewater treatment to raise pH, neutralize acidic effluents, precipitate heavy metals, and maintain optimal conditions for coagulation and flocculation. It is supplied as solid flakes/pearls or as 50% aqueous solution for direct dosing. Proper pH control is essential for effective coagulation, scale inhibition, and compliance with discharge pH limits.
