Applications & Use Cases
- ▸ Supplemental external carbon source dosed into biological wastewater treatment systems to drive denitrification when influent BOD is insufficient.
- ▸ pH buffering agent that holds process and effluent streams in a stable mildly alkaline range across plating, photographic, and general manufacturing baths.
- ▸ Acidity regulator and preservative (E-262 / INS 262(i)) in food and beverage processing, including pickling and seasoning applications.
- ▸ Concrete admixture component and de-icing constituent where its lower corrosivity relative to chloride salts is advantageous.
- ▸ Mordant and dye-bath buffer in textile finishing to control pH during fixation.
