White Granular Purity 94% Sodium Tripolyphosphate for Detergent, Technical Grade STPP for Waste Water Treatment
1. Product Introduction
White granular purity 94% sodium tripolyphosphate, commonly abbreviated as STPP, is an inorganic compound that plays a vital role in various industries and applications. It belongs to the family of polyphosphates and is composed of sodium cations (Na+) and tripolyphosphate anions (PO₃³⁻). This versatile substance is widely used for detergents, waste water treatment softner, food preservation, and various industrial processes.

3. White Granular Purity 94% Sodium Tripolyphosphate Application
Sodium tripolyphosphate function in detergent industry:
STPP is a good auxiliary in detergent industry, the usual dosage is about 10~35%, the function of STPP in detergent system are:
1. Soften the hard water by reacting with metal ions of Ca2+, Mg2+, Fe3+ and others to make them from insoluble to soluble Na5P3O10+Ca2+ ---> Na3(CaP3O10)+2Na+
2. Enhancing the emulsifying and dispersing power, to increase the solubility of protein and dust which normally existing in the fabrics from daily life
3. Buffering agent, to make the pH value of detergent solution on the level of 9~9.5, so that those acid dirt can be easily removed from fabrics
4. Anti-caking agent for detergent powder. Since detergent powder is easily caking in exposed air, STPP can absorb the moisture and become Hexahydrate, which is dry and free flowing.
Sodium tripolyphosphate function in watste water treatment:
Sodium tripolyphosphate can be used in different stages of sewage treatment. In the biochemical treatment process, adding an appropriate amount of sodium tripolyphosphate can promote the degradation and hydrolysis acidification of organic matter, and improve the efficiency of the biochemical reaction. During the coagulation and sedimentation process, sodium tripolyphosphate can serve as a chemical precipitant to form stable precipitates of phosphorus compounds in wastewater. In sludge treatment, sodium tripolyphosphate can promote sludge settling, reduce sludge volume and decay heat.
