It gives rapid and quantifiable results in denitrifying procedures. Shanxi Zhaoyi Chemical Co., Ltd., this product comes from the company, formed in 1988, with a plant of 27,000 m2 and an annual capacity of 150,000 tons. Each batch is manufactured to rigorous quality requirements. Assay content is ≥58%. Free acid content is ≤0.03%. Water-insoluble compounds are ≤0.04%.

Technical Specifications

How it enables biological denitrification

Sodium acetate, a denitrifying carbon source, is a readily available source of organic carbon for heterotrophic bacteria in anoxic zones.The bacteria employ acetate as an electron donor to reduce nitrate (NO 3 - ) to nitrogen gas (N 2 ) thereby eliminating nitrogen from the treated water.

This product has a COD equivalent of around 0.42 to 0.46 g COD/g, providing your process engineers with a valid parameter for the correct dose determination. This predictability is crucial in large scale operations because overdosing increases expense and underdosing concerns non compliance.

Its high solubility (~76 g/100 ml at 0°C) enables smooth passage through the lines of the dosing pump without crystallisation or clogging, a practical advantage that lowers maintenance downtime.

Dosage Calculation Guide

Getting the dosage right is essential. Use the following formula recommended for municipal wastewater treatment:

X = (4 − C_BOD5 / C_n) × C_n / 0.52

Where:

C_BOD5 = influent BOD₅ concentration (mg/L)

C_n = influent TN concentration (mg/L)

Practical Example:

A plant treating 160,000 m³/day with influent TN of 70 mg/L and BOD₅ of 262.5 mg/L:

X = (4 − 3.75) × 70 / 0.52 = 33.7 mg/L

Daily dosage = 33.7 × 160,000 / 1,000 = 5,392 kg/day

Adjust the amount of last raw material according to the actual purity of your product. 24/7 Technical Support Our Technical staff would be happy to support you with dose calculations and adding technique optimisation.

Why This Product Works in Wastewater Treatment

When your plant is struggling to meet total nitrogen (TN) discharge limits, the right carbon source makes all the difference. Sodium acetate for sewage treatment plants is widely preferred because it enters the microbial Krebs cycle directly. This means bacteria can use it immediately — no complex hydrolysis steps required.

Unlike glucose or methanol as carbon sources, sodium acetate trihydrate may sustain high denitrification efficiency at water temperatures below 10°C. That makes it all the more important for plants running through harsh winters without sacrificing effluent quality.

It's alkaline pH range (7.5-9.0) also helps buffer against the acidity naturally created during the denitrification process, and hence helps reduce the requirement for separate pH correction.

FAQ

Q: What is the recommended dosage of the product for a typical municipal plant?

A：Dosage is based on your influent TN and BOD5 readings. For a plant with TN 70 mg/L and BOD 5 262.5 mg/L, the need would be roughly 33.7 mg/L or about 5,392 kg/day. Using the equation X = (4 − C BOD 5 /C n ) × C n /0.52 for 160,000 m 3 /day capacity.

Q: How does sodium acetate compare to methanol or glucose as a carbon source for denitrification?

A: Sodium acetate is readily available, does not need hydrolysis and is more efficient at lower temperatures <10°C. It also yields less sludge thickening than sugar-based sources, giving a more consistent choice for all-year operation.

Q : What quality certifications does your product conform to ?

A: Each batch contains full COA and test report. Supported by third party testing by SGS. The firm is registered to ISO 9001, ISO 14001 and ISO 45001 and has Kosher and Halal certifications available for suitable classes.

Q: How about your after-sale policy? 

a: We allow unconditional return or exchange within 7 days after delivery of the goods and freight is borne by our side if the product does not match the standards and a test report is produced. Damaged transport packing will be replaced free of charge.

Q: Can you manage rush or high volume orders?

A: Yes. stock orders ship out within 24 hours. Lead time for orders above 500 tonnes is 7 days. Emergency replacements are given precedence to existing procurement files.

Q: Is it safe to store and transport the product?

A: Store in a cool, dry, well-ventilated warehouse, keep away from heat and moisture. Stay clear from hazardous substances.Unload carefully to prevent damage to packages. Refer to the complete safety information on the attached MSDS.
