Introduction
Our innovative hydrogel-iron composite biofilter media represents a quantum leap in biological wastewater treatment, specifically engineered to address the most challenging contaminants including ammonia nitrogen, total phosphorus, and recalcitrant organic pollutants. Combining sustained-release hydrogel technology with active iron ion catalysis, this advanced media delivers unparalleled performance in:
Simultaneous nitrification-denitrification
Enhanced biological phosphorus removal
Degradation of antibiotics and micro-pollutants
COD reduction in high-load industrial wastewater
Key Features & Technological Advantages
Core Technology & Mechanism
1. Dual-Action Iron Catalysis System
Endogenous Fenton-like reactions: Iron ions react with microbially-produced H₂O₂ to generate hydroxyl radicals (·OH)
Electron shuttle function: Accelerates electron transfer in denitrification process
Phosphorus precipitation: Forms stable iron-phosphate complexes
2. Smart Hydrogel Matrix
Controlled nutrient release: Maintains optimal C:N:P ratio for microbial growth
pH buffering capacity: Stabilizes reaction environment (pH 6-8.5)
Biofilm protection: Prevents biomass loss during hydraulic shocks
