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.
Rapid microbial attachment due to excellent hydrophilic properties.
Accelerates biofilm growth, improving wastewater treatment efficiency.
High wear resistance ensures long-term use without degradation.
Resistant to chemical corrosion, suitable for harsh wastewater conditions.
