Potassium dihydrogen phosphate (KH₂PO₄) is an important chemical product that is widely used in agriculture, food, medicine, and industry. In recent years, with the acceleration of the global agricultural modernization process and the promotion of environmental protection policies, the potassium dihydrogen phosphate market has shown a rapid development trend.
Applications in Water Treatment
Corrosion inhibitor: Potassium dihydrogen phosphate can be added as a corrosion inhibitor to water treatment systems, especially in boiler water and cooling water systems. It can form stable complexes with calcium and magnesium ions in water to reduce the formation of scale, thus protecting equipment from corrosion.
pH regulator: Potassium dihydrogen phosphate has a certain buffering capacity and can be used to regulate the pH value of the water body to keep it in a suitable range (usually 6.5-8.5), thus optimizing the water treatment effect.
Nutrient source: In sewage treatment (such as biological treatment process), potassium dihydrogen phosphate can be used as a phosphorus source to provide essential nutrients for microorganisms, promote the growth and metabolism of microorganisms, and improve the efficiency of sewage treatment.
Advantages in Water Treatment
- High efficiency: As a corrosion inhibitor and pH regulator, potassium dihydrogen phosphate has a remarkable effect and can effectively prevent scale and corrosion.
- Environmental protection property: Potassium dihydrogen phosphate is a relatively environmentally friendly chemical that does not cause serious secondary pollution to water bodies.
- Ease of solubility: Potassium dihydrogen phosphate is soluble in water, easy to use, and can work quickly.
