Application Scope
1、Carbon source supplement: Addition amount in denitrification and nitrogen removal process is 100 - 300mg/L, COD contribution value increases by 40%.
2、pH adjustment: Neutralize acidic wastewater, reaction efficiency reaches 95%.
3、Acidity regulator: Addition amount in potato chips and seasonings is 0.1% - 0.5%, shelf life is extended by 30%.
4、Substitute for preservatives: After the new regulation in 2024 prohibits the use of dehydroacetic acid sodium, demand for bread products increases by 25%.
5、Medical dialysis solution: Adjust electrolyte balance, dosage is 0.5% - 1.5%.
6、Plating corrosion inhibitor: Addition amount in acidic plating solution is 3% - 5%, reduces metal corrosion rate.
