Polyferric Sulfate shows different effects in different water qualities.
1. Effects in industrial wastewater treatment
For industrial wastewater containing a large amount of heavy metal ions, Polyferric Sulfate can play an important flocculation role. It forms stable complexes with heavy metal ions to precipitate them, thereby reducing the content of heavy metals in the water. For example, in electroplating wastewater treatment, Polyferric Sulfate can effectively remove heavy metal ions such as copper, nickel, and zinc. At the same time, for some industrial wastewaters containing high concentrations of organic matter, Polyferric Sulfate can also aggregate organic matter to form larger particles through adsorption and flocculation, which is convenient for subsequent precipitation or filtration removal. However, the components of different types of industrial wastewater are complex and diverse, which may affect the effect of Polyferric Sulfate. For example, some wastewater contains a large amount of surfactants or other interfering substances, which may reduce the flocculation effect of Polyferric Sulfate.
2. Effects in domestic sewage treatment
In domestic sewage, Polyferric Sulfate is mainly used to remove pollutants such as suspended matter, organic matter and phosphorus. It can make the fine particles in the sewage condense into larger flocs, thereby accelerating the sedimentation speed and improving the sewage treatment efficiency. For domestic sewage containing a certain amount of grease, Polyferric Sulfate can also play a certain role in demulsification, separating the grease from the water. However, the water quality of domestic sewage is relatively stable, and the dosage of Polyferric Sulfate is usually smaller than that of industrial wastewater. Moreover, the organic components in domestic sewage are relatively complex, which may react with Polyferric Sulfate to a certain extent, affecting its flocculation effect.
3. Effects in water with different pH values
The pH value of water quality has a significant effect on the effect of Polyferric Sulfate. Generally speaking, Polyferric Sulfate works better under acidic and neutral conditions, while its flocculation effect will be reduced under alkaline conditions. This is because in an alkaline environment, Polyferric Sulfate is easily hydrolyzed to form iron hydroxide precipitation, thereby reducing the content of its effective ingredients. In addition, under different pH values, the form of pollutants in water will also change, further affecting the effect of Polyferric Sulfate.
In short, the effect of Polyferric Sulfate in different water qualities is different, and it is necessary to make reasonable selection and adjust the dosage according to the specific water quality conditions to achieve the best treatment effect.
