As a leading manufacturer in Qingdao, Shandong, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been dedicated to producing high-quality Industrial Grade Sodium Acetate Trihydrate since 2015. With a factory spanning over 10,000 square meters and an annual export value exceeding US$10 million, we supply this essential chemical to wastewater treatment plants worldwide. Our product serves as an efficient external carbon source for biological denitrification, helping industries meet stringent effluent standards while reducing operational costs.
Sodium Acetate Trihydrate (CH₃COONa·3H₂O) is a versatile compound widely used in municipal and industrial wastewater treatment systems. It provides readily available carbon for microorganisms, enhancing the removal of nitrogen and phosphorus compounds. Our industrial-grade formulation ensures high purity and consistent performance, making it a reliable choice for treatment facilities across North America, Europe, Southeast Asia, and beyond.
Below are the key specifications and benefits that set our Sodium Acetate Trihydrate apart from conventional alternatives:
Key Features & Technical Specifications
- High Purity (≥58% Anhydrous Basis) – Ensures maximum carbon availability per kilogram, reducing dosage requirements.
- Controlled pH Buffering – Maintains stable pH levels in biological reactors, preventing fluctuations that harm microbial activity.
- Rapid Solubility – Dissolves quickly in water (76.2 g/100 mL at 20°C), allowing uniform distribution in treatment tanks.
- Low Heavy Metal Content – Manufactured under strict quality control to minimize impurities that could inhibit biological processes.
- Customizable Packaging – Available in 25kg bags, 50kg bags, or 1-ton jumbo bags to suit your logistics needs.
- Long Shelf Life (2 Years) – Stable under proper storage conditions, reducing waste and inventory turnover.
| Parameter | Specification | Benefit |
|---|---|---|
| CAS No. | 6131-90-4 | Standard identification for regulatory compliance |
| Molecular Weight | 136.08 g/mol | High carbon content per mole reduces storage volume |
| pH (5% solution) | 7.5 – 9.0 | Prevents acidification in denitrification tanks |
| Heavy Metals (as Pb) | ≤ 10 ppm | Safe for biological systems and final discharge |
| Iron (Fe) | ≤ 5 ppm | Prevents staining and equipment fouling |
| Chloride (Cl) | ≤ 0.02% | Minimizes corrosion in piping and tanks |
Application Advantages in Wastewater Treatment
Our Industrial Grade Sodium Acetate Trihydrate is specifically formulated to serve as an external carbon source in biological nutrient removal (BNR) processes. Here are the primary application scenarios:
- Denitrification Enhancement – Heterotrophic bacteria require organic carbon to convert nitrate (NO₃⁻) to nitrogen gas. Sodium acetate provides an easily metabolized carbon source, increasing denitrification rates by up to 50% compared to methanol or ethanol.
- Biological Phosphorus Removal (EBPR) – Polyphosphate-accumulating organisms (PAOs) use acetate as a substrate to uptake phosphorus under anaerobic conditions, improving total phosphorus removal efficiency.
- pH Buffering for Sensitive Systems – Unlike strong acids or bases, sodium acetate gently adjusts pH without causing shock to microorganisms, ideal for nitrification-denitrification processes.
- Cold Temperature Operation – Even at low temperatures (5–15°C), sodium acetate remains highly soluble and bioavailable, ensuring stable performance in winter months.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between industrial grade and food grade sodium acetate trihydrate?
A: Industrial grade is designed for wastewater treatment with slightly lower purity requirements but still meets stringent heavy metal limits. Food grade is certified for human consumption. Our product is strictly industrial grade, optimized for cost-effective carbon dosing. -
Q: Can this product be used in combination with other chemicals?
A: Yes. Sodium acetate trihydrate is compatible with common coagulants (e.g., alum, ferric chloride) and polymers. However, we recommend a jar test to determine optimal dosing and avoid adverse reactions. -
Q: How should I store sodium acetate trihydrate to prevent caking?
A: Store in a cool, dry environment below 30°C with relative humidity under 60%. Use sealed containers and avoid exposure to moisture. If caking occurs, it can be crushed or dissolved without loss of performance. -
Q: Do you provide free samples for testing?
A: Yes, we offer complimentary 1–5 kg samples for qualified wastewater treatment plants. Please contact our sales team with your treatment volume and expected dosage rate. -
Q: What is the typical dosage rate in denitrification?
A: Dosage depends on nitrate concentration and flow rate. A general guide: 2–4 kg of sodium acetate trihydrate per kg of nitrate nitrogen removed. We can assist with custom dosing calculations. -
Q: Is this product hazardous for transportation?
A: No. Sodium acetate trihydrate is classified as non-hazardous under most regulations (UN number not assigned). It is safe for road, sea, and air freight when properly packaged. -
Q: How long does it take to dissolve in cold water?
A: At 10°C, it dissolves within 5–10 minutes with moderate stirring. For faster dissolution, pre-dissolve in a small amount of warm water before addition to the main tank. -
Q: Can you customize the particle size or packaging?
A: Yes, we offer customizable packaging (bags, drums, FIBC) and can produce granules or fine crystals upon request. Contact us for specific requirements.
