1. Cleaning & Disinfectants Solutions 

• Degreasers – Trisodium phosphate (TSP) is commonly used as a strong alkaline cleaner to remove grease, oil, and stains from surfaces, especially in industrial cleaning. 
• Disinfectants – TSP helps in the cleaning and sanitizing of bathrooms, kitchens, and floor surfaces. 

2. Water Treatment  

• Water Softening – Used in water treatment to remove hardness caused by calcium and magnesium ions. 
• Ph Control – Helps in adjusting the pH of water for specific industrial processes like boiler water treatment or cooling towers. 
• Flocculant – Used as a coagulant to help in removing impurities from water by aiding in the formation of flocs. 

3. Metal Treatment  

• Rust Remover – TSP is used as a rust remover in the cleaning and preparation of metals before coating or painting. 
• Electroplating – Acts as a cleaning agent in the electroplating process, ensuring metal surfaces are clean and prepared for plating. 
• Etching Agent – Can be used in etching processes in the production of metal parts and electronics. 

4. Construction  

• Concrete Cleaner – Used to clean concrete surfaces before applying finishes like paints or sealants. 
• Degreasing Agent – Helps in removing grease, oil, and other contaminants from concrete during construction and renovation. 
• Efflorescence Removal – Trisodium phosphate is effective in removing efflorescence (salt deposits) from masonry and brickwork. 

5. Agrochemicals 

• Fertilizer Additive – Trisodium phosphate can be used as a source of phosphorus in agricultural fertilizers, contributing to plant growth. 
• Herbicide and Pesticide Formulation – Used in some formulations to stabilize active ingredients in herbicides or pesticides.
