Introduction
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.
Key Features & Benefits
1. Superior Hydrophilicity for Rapid Biofilm Formation
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.
2. High Surface Area & Optimal Microbial Load
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.

Why Choose PCG Over Conventional Biofilm Carriers?
✔ 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.
FAQ
Q1: How does PCG compare to traditional plastic bio carriers?
PCG offers a larger surface area, better oxygen transfer, and faster biofilm growth due to its hydrophilic properties.
Q2: What is the expected lifespan of PCG?
Under normal conditions, PCG lasts over 10 years without significant wear.
Q3: Can PCG be used in anaerobic systems?
Yes, it is adaptable to both aerobic and anaerobic environments.
Q4: How much PCG media is needed per m³ of reactor?
The filling ratio typically ranges from 30% to 70%, depending on the system design.
Q5: Is PCG suitable for high-salinity wastewater?
Yes, it performs well in saline conditions, making it ideal for industries like seafood processing.
