Product Overview:
After six years of research, we selected a high-polymer hydrophilic material with superior bio-affinity, wear resistance, aeration efficiency, and an ultra-high surface area. PCG was officially launched in 2016, underwent five years of small- and medium-scale testing, and entered mass production in 2020. Today, PCG stands as a leading biological media carrier in the market, outperforming competitors in efficiency and durability.
Key Features
1. High Hydrophilicity & Biofilm Formation
Rapid microbial attachment due to excellent hydrophilic properties.
Accelerates biofilm growth, improving wastewater treatment efficiency.
2. Superior Material Durability
High wear resistance ensures long-term use without degradation.
Resistant to chemical corrosion, suitable for harsh wastewater conditions.
