Sodium Acetate
Sodium acetate serves as an excellent carbon source for biological denitrification to address total nitrogen exceedance issues. It can also regulate water pH value and improve sludge dewatering. Two major functions of sodium acetate: supporting microbial activity and stabilizing water quality parameters, making it an indispensable key chemical in biological water treatment systems.
- Easily Degradable
- Rapidly Activate Bacteria
- Accelerate Denitrification
- Stable Purify Effect
- Low-temperature Adaptability
Sodium Acetate Description
In biological treatment processes for water treatment (such as A²/O, MBR, SBR, etc.), microbial require carbon sources as energy and raw materials for cell synthesis when degrading nitrogen in water. When the carbon content in wastewater is insufficient, denitrifying bacteria activity significantly decreases, leading to low total nitrogen removal rates. Therefore, artificial carbon source addition is essential. Sodium acetate has the following functions:
- Direct microbial utilization, high efficiency
As an easily degradable carbon source, sodium acetate requires no additional microbial breakdown. It directly crosses cell membranes to enter cells for metabolic processes, rapidly activating denitrifying bacteria and shortening denitrification reaction time.
- Stable control of denitrification performance
Sodium acetate possesses a stable carbon content (COD value) and allows precise dosage calculation. This prevents effluent COD exceedances due to excess carbon sources, or total nitrogen exceedances due to insufficient carbon sources, making it particularly suitable for scenarios with strict effluent quality requirements.
- Adaptability to low temperatures
Low temperature (e.g., water temperature <15°C in winter) inhibits microbial activity. Sodium acetate demonstrates superior cold tolerance, maintaining denitrification efficiency at lower temperatures to ensure stable operation of water treatment systems even in winter.

Sodium Acetate Applications
Sodium acetate plays a vital role across multiple industries:
Wastewater Treatment: Used as a carbon source, providing nutrients for denitrifying bacteria to remove nitrate nitrogen from wastewater.
Textile Dyeing: Used as a buffer and neutralizing agent, regulating dye bath pH value to enhance dyeing rate and color fastness.
Food: Used as a preservative and flavoring agent in beverages, pickled vegetables, condiments, etc. It regulates acidity, inhibits microbial growth, and extends food shelf life.
Pharmaceutical: Used as a buffer agent and diuretic component in drug formulations, ensuring drug stability and efficacy.
