Polyferric sulfate (PFS) is a cutting-edge, highly effective inorganic polymer flocculant known for its robust electrical neutralization prowess and exceptional adsorption bridging capabilities. Upon hydrolysis, it forms a sophisticated multi-core complex that swiftly eliminates colloids, suspended particles, and organic impurities from water. Its sedimentation efficiency surpasses traditional aluminum-based salts. Tailored for municipal and industrial wastewater treatment, including sectors like papermaking, printing, dyeing, and electroplating, PFS excels in phosphorus removal, decolorization, and heavy metal extraction. It boasts a broad pH range applicability, minimal residual iron, and dense, low-volume sludge, significantly lowering post-treatment expenses. With its minimal dosage requirements and cost-effectiveness compared to similar alternatives, PFS is celebrated for its dual coagulation and oxidation capabilities. Its superior efficacy, safety profile, and adaptability make it indispensable in modern water treatment solutions.
PFS Core Product Features
