Trisodium Phosphate Regulates pH Value
1. Strong Alkaline Property
When trisodium dihydrate dissolves in water, it dissociates into PO₄³⁻ ions, making the solution strongly alkaline (pH≈11-12), and is an ideal pH regulator and buffer.
2. Specific Functions
Neutralize acidic wastewater: Used in electroplating, chemical engineering, printing and dyeing and other industries to neutralize acidic wastewater (such as residual sulfuric acid and hydrochloric acid), and prevent corrosion of pipelines and equipment.
Stabilize the pH value of the system: In boiler water and circulating cooling water, it can maintain an alkaline environment (pH 9-11) for a long time, prevent acidic corrosion and extend the service life of equipment.
Compared with NaOH (caustic soda), its alkalinity is milder and it is less likely to cause local excessive alkalinity.
Used in combination with other water treatment agents: When compounded with corrosion inhibitors (such as sodium silicate) and scale inhibitors (such as sodium hexametaphosphate), it optimizes the water treatment effect.
3. Practical Application Scenarios
Industrial wastewater treatment: Adjust the acidic wastewater to neutral to meet the discharge standards (such as pH 6-9).
Boiler water treatment: Maintain an alkaline environment, prevent acidic corrosion and oxygen corrosion, and protect metal pipes.
Electroplating/metal surface treatment: Used for neutralization after degreasing and pickling to prevent the corrosion of the workpiece by residual acid.
4. Precautions for Use
Dosage control: Needs to be adjusted in real time according to the pH of the water quality. Excessive use may cause the pH to be too high (>12), affecting subsequent treatment.
Phosphorus content limit: The discharge of wastewater containing phosphate must comply with environmental protection standards. If necessary, chemical precipitation methods (such as adding aluminum salts or iron salts) should be used in combination for phosphorus removal.
Solubility: Hydrates are more soluble than anhydrous products and are suitable for rapid pH adjustment, but they have lower active ingredients and the actual dosage needs to be calculated.
