Caustic Soda (Sodium Hydroxide)
Caustic soda is commonly used in water & wastewater treatment to raise the pH of water. Unlike the use of lime, caustic soda will raise the pH of water without the addition of calcium ion that will result in calcium carbonate scaling as well as shifting from bicarbonate alkalinity to carbonate alkalinity.
Packaging: 25kg bags.
