Caustic Soda

Caustic Soda (Sodium Hydroxide, NaOH) is a strong alkali widely used in water treatment, soap and detergent production, paper manufacturing, and chemical industries. It is a white solid (often in flakes, pellets, or solution) that dissolves easily in water, releasing heat, and is highly corrosive to skin and metals.

 Chemical Specification:

 Chemical Formula    : NaOH
 CAS Number            : 1310-73-2
 Appearance              : white and crystalline, often appearing as flakes or pellets
 NaOH                       : 98.51 %w/w
 Na2CO3                   : 0.28 %w/w
 NaCl                         : 60.00 ppm
 Fe                             : 7.50 ppm
 Cu                             : <2.00 ppm

 Application:

• It is used to neutralize or adjust the pH in different wastewater plants.

• Steps like coagulation, flocculation, and disinfection work in a specific pH range, and caustic helps to attain that range.

• It helps to remove heavy metals by removing dissolved heavy metals.

• Sometimes it works as a coagulation and flocculation Aid.

•  It helps to regenerate ion exchange resins.
