Polyferric Sulfate (PFS): A High-Efficiency and Eco-Friendly Coagulant for Water Treatment
2023/5/4
Polyferric Sulfate (PFS) is a type of inorganic polymer that consists of multiple iron and sulfate ions linked together by oxygen bridges. PFS is mainly used as a coagulant in water treatment processes, such as drinking water purification, wastewater treatment, industrial effluent treatment, and sludge dewatering.
PFS can improve the efficiency and quality of water treatment by forming large and dense flocs that can capture and remove suspended solids, colloids, organic matter, heavy metals, phosphorus, and microorganisms from water. PFS can also reduce the turbidity, color, odor, and toxicity of water by oxidizing and precipitating pollutants and impurities. PFS can also lower the pH and alkalinity of water by releasing hydrogen ions, which can enhance the coagulation and disinfection processes.
PFS is a high-efficiency and eco-friendly coagulant that can offer many advantages over conventional coagulants, such as aluminum sulfate and ferric chloride. For example, PFS has a higher coagulation activity and a wider applicable pH range than aluminum sulfate and ferric chloride. PFS also has a lower dosage and a lower residual iron content than aluminum sulfate and ferric chloride. PFS also has a lower corrosivity and a lower sludge production than aluminum sulfate and ferric chloride. PFS also has a better biodegradability and a lower environmental impact than aluminum sulfate and ferric chloride.
PFS is a promising coagulant that can improve the quality of life and environment by enhancing the efficiency and quality of water treatment. However, PFS also has some drawbacks and challenges that need to be addressed. For example, PFS has a higher cost and a lower availability than aluminum sulfate and ferric chloride. PFS also has a complex synthesis process and a variable composition depending on the raw materials and conditions. PFS also has a limited stability and a short shelf life compared to aluminum sulfate and ferric chloride. Therefore, PFS needs to be carefully prepared, stored, transported, applied, monitored, and disposed of according to the specific conditions and regulations.
PFS is a novel coagulant that can improve the quality of life and environment by enhancing the efficiency and quality of water treatment. By understanding its properties, mechanisms, advantages, and limitations, we can use PFS more wisely and responsibly.
