In wastewater treatment, biofilm carriers play a crucial role in determining effluent quality. As a core component of biological treatment systems, the performance of the carrier directly affects microbial attachment, biofilm formation, and overall pollution removal efficiency.
Faster microbial colonization due to high water absorption.
Reduces startup time for new wastewater treatment systems.
Enhances nutrient absorption, improving COD, BOD, and nitrogen removal.
Unique wall structure maximizes effective surface area (800–1200 m²/m³).
Supports high biomass retention, increasing treatment capacity.
Prevents microbial loss under high water and air shear forces.

Municipal sewage (e.g., Riyadh, Jeddah plants).
Industrial wastewater (oil refineries, textile dyeing).
Rural drainage & river remediation.
Case Example: A Saudi textile plant achieved 95% COD removal by replacing conventional carriers with PCG.
✔ Faster Treatment Efficiency – High biofilm retention improves ammonia & nitrogen removal.
✔ Lower Operational Costs – Reduces aeration energy by 20–30%.
✔ Longer Lifespan – No degradation in high-load industrial wastewater.
✔ Wider Compatibility – Works in aerobic, anoxic, and anaerobic systems.
✔ Easy Installation – Lightweight, flexible for retrofitting existing plants.
PCG offers a larger surface area, better oxygen transfer, and faster biofilm growth due to its hydrophilic properties.
Under normal conditions, PCG lasts over 10 years without significant wear.
Yes, it is adaptable to both aerobic and anaerobic environments.
The filling ratio typically ranges from 30% to 70%, depending on the system design.
Yes, it performs well in saline conditions, making it ideal for industries like seafood processing.
