High-purity industrial sodium acetate for biological denitrification — the fast-acting external carbon source that helps wastewater plants hit tighter total nitrogen limits.

When wastewater is carbon-limited, denitrifying bacteria cannot convert nitrate to nitrogen gas — and total nitrogen in the effluent exceeds the permit. Sodium acetate is the preferred external carbon source: it is consumed faster and more completely than methanol (no acclimation period, no hazardous storage) and more reliably than complex sugars, giving stable denitrification in anoxic zones and deep-nitrogen-removal retrofits.
Our industrial grade sodium acetate carries 58-60% active content per HG/T 2031-2008, low moisture and low insolubles for clean dosing preparation. Municipal WWTPs upgrading for stricter TN discharge — increasingly common across Vietnam and Indonesia — are our core users, and we support jar-scale dosing trials with technical guidance.
