Sodium acetate is a substance that can be easily made with vinegar and baking soda. As the mixture cools below its melting point, it crystallizes. Crystallization is an exothermic process, so these crystals actually generate heat, which is why the substance is often called hot ice. This compound has a variety of industrial and everyday uses.
Main use
In the food industry, sodium acetate is used as a preservative and pickling agent. Because salt helps foods maintain a specific pH, it prevents harmful bacteria from growing. In the pickling process, a large amount of this chemical is used, not only as a buffer for food and microorganisms, but also to improve the taste of food.
As a cleaning agent, sodium acetate neutralizes large amounts of sulfuric acid emitted from factories. It maintains a shiny metal surface by removing rust and stains. It can also be found in leather tanning solutions and image processing solutions.
Many environmental protection companies use sodium acetate for wastewater treatment. What are the main uses and methods of use and indicators?
Sodium acetate solution
Main uses:
The effects of mud age (SRT) and additional carbon source (sodium acetate solution) on nitrogen and phosphorus removal were studied. Sodium acetate was used as a carbon source to acclimate the denitrification sludge, and then the rise of pH value was controlled within 0.5 by buffer solution. Denitrifying bacteria can overabsorb CH3COONa, so the effluent COD value can be maintained at a low level when CH3COONa is used as additional carbon source for denitrification. At present, the sewage treatment of all cities and counties needs to add sodium acetate as a carbon source if it wants to meet the discharge level I standard.
