Advanced Biofilm Carrier for Enhanced Nitrogen/Phosphorus Removal and Recalcitrant Pollutant Degradation
This innovative biofilm carrier is specifically engineered to address three critical wastewater treatment challenges: efficient nitrogen removal, enhanced phosphorus elimination, and degradation of persistent organic pollutants. The technology combines two breakthrough mechanisms
Hydrogel Sustained-Release System
Maintains optimal moisture and nutrient levels for microbial communities
COD removal efficiency: 85-95%
Ammonia nitrogen removal: 90-98%
Heavy metal adsorption capacity: 15-30mg/g (Pb²⁺, Cd²⁺, Cu²⁺)
pH resistance: 2-12 (withstands extreme industrial wastewater)
Operational lifespan: 5+ years (3X longer than conventional plastic media)
Compressive strength: ≥3.5MPa (resists mechanical wear)
| Parameter | Value |
|---|---|
| Material | Polyurethane porous gel |
| Specific Surface Area | ≥10,000 m²/m³ |
| Porosity | 98% |
| Dosing Rate | 10–30% of tank volume |
| Hanging Time | 3–7 days |
| pH Range | 6–10 |
| Temperature Range | 1–50°C |
| Expansion Ratio | 190 ± 18% (1:2.2 post-swelling) |
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.
Pharmaceutical wastewater (antibiotics, hormones)
Chemical plant effluent (nitro-compounds, dyes)
Landfill leachate (high ammonia, refractory COD)
Electroplating wastewater (complex heavy metals)
Sewage plant upgrades (Class IV to Class I-A standards)
Aquaculture recirculation systems
Hospital wastewater disinfection
River/lake eutrophication control
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.
PCG Biological Media Carrier is a cutting-edge solution for modern wastewater treatment, combining Japanese-inspired design with advanced polymer technology. Its high efficiency, durability, and cost-effectiveness make it an ideal choice for projects in Saudi Arabia, the Philippines, Indonesia, Malaysia, and beyond. For sustainable and high-performance biofilm treatment, PCG leads the industry.
