CAS 6131-90-4 Sodium Acetate Trihydrate Wastewater Treatment Industrial Grade

Sodium acetate properties

1. Chemical properties
Chemical formula: CH₃COONa
Molecular weight: 82.03 g/mol (anhydrous matter); 136.08 g/mol (trihydrate)
Structure: Composed of the radical acetate ion (CH₃COO⁻) and sodium ion (Na +).
pH value: The aqueous solution is weakly alkaline, pH is about 8-9.
2. Physical properties
Appearance:
Anhydrous sodium acetate: white crystalline powder.
Sodium acetate trihydrate (CH₃COONa·3H₂O) : colorless transparent crystal.
Solubility:
Soluble in water, solubility increases significantly with temperature (at 20°C, about 46.5 g per 100 mL of water).
Slightly soluble in ethanol, insoluble.
Melting point:
Anhydrous sodium acetate: 324°C.
Sodium acetate trihydrate: 58°C (dehydration decomposition).
Density:
Anhydrous sodium acetate: 1.528 g/cm³.
Sodium acetate trihydrate: 1.45g /cm³.
Hygroscopic: Sodium acetate trihydrate is easy to hygroscopic, and anhydrous sodium acetate hygroscopic is low.
3. Thermal stability
Heated decomposition. When heated to high temperatures, sodium acetate decomposes to
form sodium carbonate (Na₂CO₃) and methane (CH₄)


How about sodium acetate sewage treatment

Step 1: Application
(1) Dechlorination agent
Principle of action:
Sodium acetate can be used to remove residual chlorine in water and improve water quality.
Application scenario:
Drinking water treatment: Remove residual chlorine in drinking water to improve water quality.
Industrial water treatment: Remove residual chlorine in industrial water to prevent equipment corrosion.
(2) Nutrients
Principle of action:
Sodium acetate can be used as a nutrient to promote the growth and metabolism of microorganisms.
Application scenario:
Sewage treatment: Used in activated sludge method and biofilm method to improve the efficiency of sewage treatment.

2. Use precautions
Dosage control:
According to the concentration of pollutants in sewage and treatment needs, the amount of
sodium acetate should be controlled reasonably to avoid excessive use.
Precipitation treatment:
The resulting sediment needs to be separated by filtration or sedimentation tank to avoid secondary pollution.
Safety protection:
Sodium acetate is less toxic to humans, but it is still necessary to wear protective gear
and avoid direct contact with skin and eyes.

Step 3: Advantages
High efficiency: can quickly remove pollutants in sewage.
Economy: Low cost, suitable for large-scale sewage treatment.
Environmental protection: friendly to the environment, easy to degrade.
