Application & Characteristics | |
Product Characteristics | High-Efficiency Coagulation,Decolorization & Deodorization,Sludge Dewatering Aid,Low Corrosiveness,No Secondary Pollution |
Product Function | Hydrolyzes in water to produce various high-valent polynuclear ferric complexes, which remove colloidal particles and suspended solids through charge neutralization, adsorption bridging, and sweep flocculation. |
Main Applications | Potable Water Treatment,Industrial Water Purification, Purification of variousIndustrial Wastewaters(dyeing, plating, oily, etc.) andMunicipal Sewage. |
Core Advantages | 1.Excellent Treatment Efficiency: High removal rates for suspended solids, organics, heavy metals, and phosphorus; effective in decolorization, deodorization, and demulsification. |
2.Broad pH Adaptability: Effective within a wide pH range of 4-11. | |
3.Safe & Eco-friendly: Non-toxic, less corrosive than conventional ferric salts, and causes no secondary pollution. | |
4.Superior Sludge Dewatering: Produces dense, fast-settling flocs that are easy to dewater. | |
Water-in-Oil (W/O) Emulsion: Requires "activation/inversion" via specific stirring and dilution procedures before dissolution. | |
