Application and Function of Iron sulfide 0-5mm with Powder in Wastewater Treatment
Fine granular pyrite ore with powder has a large specific surface area and high reactivity, making it suitable for use as powder filler or modified raw material in wastewater treatment.
Core Application Scenarios and Mechanisms
Enhanced Filler for Advanced Oxidation / Fenton Process
Directly added to Fenton reactors or ozone catalytic oxidation towers to efficiently degrade refractory organic pollutants such as those in printing and dyeing and chemical wastewater, reducing COD and chroma.
Rapid Precipitant for Heavy Metal Wastewater
Suitable for acidic heavy metal wastewater from electroplating, metallurgy, mining and other industries. It can be directly added as a chemical precipitant to rapidly form stable sulfide precipitates with Cu²⁺, Pb²⁺, Cd²⁺, Ni²⁺, etc., with a removal effect significantly better than that of bulk fillers.
Pretreatment of High-Concentration Organic Wastewater
Used for the pretreatment of high-concentration organic wastewater such as aquaculture, food and pharmaceutical wastewater. The reduction effect of FeS₂ destroys macromolecular organic matter, reduces toxicity and viscosity, and improves the efficiency of subsequent biochemical treatment.
Iron and Manganese Removal from Groundwater and Slightly Polluted Water Sources
As a groundwater remediation material, it converts Fe²⁺ and Mn²⁺ in water into insoluble precipitates such as Fe(OH)₃ and MnO₂ through redox reactions to achieve rapid purification.
Cost Advantages
Natural raw ore is low in cost and high in utilization efficiency in powder form, making it suitable for large-scale, low-cost industrial wastewater treatment projects.
