PCG Biofilm Carrier is a soft, high-performance biological media designed to maximize microbial growth while ensuring long-term durability. With excellent hydrophilicity, a unique wall structure, and an ultra-high surface area, PCG enhances the treatment of ammonia nitrogen (NH₃-N), total nitrogen (TN), and organic pollutants. Additionally, its soft texture prevents abrasion in water treatment equipment, making it an ideal choice for modern biofilm processes such as MBBR (Moving Bed Biofilm Reactor) and IFAS (Integrated Fixed-Film Activated Sludge).
Breaks down air bubbles efficiently, improving aeration performance.
Reduces energy consumption in aeration tanks.
No dead zones, ensuring uniform biofilm growth.
Non-abrasive texture protects mixers, aerators, and pumps.
Long lifespan (10+ years) even in harsh wastewater conditions.
Resistant to chemical corrosion (pH 3–10).
Compact design allows high filling ratios (30–70%).
Ideal for both new and retrofit wastewater plants.
Suitable for aerobic, anoxic, and anaerobic conditions.
