Wastewater Treatment Sodium Acetate 58~60% Buffer Sodium Acetate Trihydrate

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

1. Carbon source supplement
Principle of action:

Sodium acetate can be used as a carbon source to promote the growth and metabolism of microorganisms.

In the biological treatment process, sodium acetate provides organic carbon

and enhances the activity of microorganisms.

Application scenario:

Activated sludge process: used in activated sludge process to improve the efficiency of sewage treatment.

Biofilm method: Used in biofilm method to enhance the activity of biofilm.

Denitrification process: as a carbon source, promoting denitrifying bacteria to convert nitrates into nitrogen.

2. pH regulator
Principle of action:

Sodium acetate solution is weakly alkaline and can be used to regulate the pH value of sewage.

By adjusting the pH value, it promotes the precipitation of heavy metal ions and the growth of microorganisms.

Application scenario:

Comprehensive sewage treatment: Adjust the pH value of sewage to meet discharge standards.

Industrial wastewater treatment: Adjust the pH value of industrial wastewater to improve treatment efficiency.

3. Heavy metal removal
Principle of action:

Sodium acetate can react with some heavy metal ions (such as lead, chromium, copper, zinc, etc.) to

form insoluble precipitates.

The resulting sediment can be separated by filtration or sedimentation tanks,

thereby removing heavy metals from the sewage.

Application scenario:

Electroplating wastewater treatment: remove lead, chromium, copper

and other heavy metal ions in electroplating wastewater.

Metallurgical wastewater treatment: remove zinc, nickel and other heavy metal ions in metallurgical wastewater.

4. Enhance flocculation effect
Principle of action:

Sodium acetate can be used as a flocculating agent to enhance the effect of

flocculants (such as polyaluminum chloride, polyacrylamide).

By improving the performance of flocculant, the removal efficiency of heavy metal ions was increased.

Application scenario:

Industrial wastewater treatment: used to improve the removal rate of heavy metals in flocculation precipitation process.
