What is Sodium Bisulfate used for

Posted on March 23rd, 2024

Sodium bisulfate, also known as sodium hydrogen sulfate, is a chemical compound with various uses in different industries. Here are some common applications of sodium hydrogen sulfate:

1. Pool Water Treatment: Sodium bisulfate is often used in swimming pools and spas to lower pH levels and alkalinity. It helps maintain the proper chemical balance in the water, ensuring swimmer comfort and preventing issues like scale formation and cloudy water.

2. Household Cleaning Products: Sodium bisulfate is found in some household cleaning products, such as toilet bowl cleaners, metal cleaners, and dishwasher detergents. It helps remove mineral deposits and stains due to its acidic properties.

3. pH Adjustment in Water Treatment: In water treatment processes, sodium hydrosulfate is used to adjust the pH of water. It can help neutralize alkaline water and make it more suitable for various industrial processes.

4. Food Additive: Sodium hydrogen sulfate is WHO/FAO approved food additive used in antimicrobial washing solutions (FAO JECFA Monographs 4)or used as acidifier or acidity regulator.( FAO JECFA Monographs 7) https://www.fao.org/food/food-safety-quality/scientific-advice/jecfa/jecfa-additives/detail/en/c/493/.

5. Feed additive: Sodium bisulfate is approved by EU as a feed additive for all terrestrial animal species (category: technological additive; functional group: preservative), and for all terrestrial animal species other than cats, mink, pets and other non-food-producing animals (category: technological additive; functional group: acidity regulator). It is also an acidity regulator and flavoring compound in all pets and other non-food-producing animals except aquatic animals.

6. Poultry Litter Treatment(PLT): Sodium bisulfate is found to be an ideal treatment for poultry houses as it not only lowers pH level of the litter, but also absorbs ammonia spread in poultry houses.

7. Textile Industry: Sodium bisulfate is used in the textile industry for dyeing and printing processes. It can help fix dyes to fabrics and adjust pH levels during textile treatments.

8. Metal Finishing: In metal surface treatments applications, sodium hydrosulfate is used for cleaning and etching metal surfaces before plating or coating processes. It helps prepare the metal for subsequent treatments.

9. Chemical Manufacturing: Sodium bisulfate is used in the production of various chemicals and industrial products. It serves as a raw material in the synthesis of other compounds and plays a role in chemical reactions.

Overall, sodium bisulfate is a versatile compound with diverse applications in industries ranging from water treatment to food production and chemical manufacturing. Its acidic properties make it valuable for pH adjustment, cleaning, and various industrial processes.
