Introduction
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).
Key Features & Benefits
1. Excellent Bubble Cutting & Oxygen Transfer Efficiency
Breaks down air bubbles efficiently, improving aeration performance.
Reduces energy consumption in aeration tanks.
No dead zones, ensuring uniform biofilm growth.
2. Soft & Durable Material – No Equipment Wear
