Discover how MBBR biofilm carriers achieve 95%+ COD removal across sewage plants, industrial effluents, and RAS aquaculture. Explore 30+ global case studies and request a custom solution.

1. Core Advantages: Why MBBR?

(Keywords: biofilm carriers, wastewater treatment process, nitrification efficiency)

  • Microbial Density Breakthrough
    • HDPE carriers with ≥850 m²/m³ surface area host 5-8x more biomass than activated sludge (per 2025 IWA research).
    • Maintains 80% denitrification efficiency at 10°C (MIT cold-weather study).
  • Engineering Superiority
    • Zero-downtime retrofits: A 100,000m³/day Chinese plant upgraded with only 12 hours of shutdown.
    • 3x shock load resistance versus conventional methods (proven in Jiangsu chemical park).

2. Cross-Industry Applications

(Keywords: industrial wastewater, black-odor river remediation, RAS aquaculture)

A. Municipal Sewage Upgrades

  • Shenzhen WWTP: Reduced COD from 120mg/L to <30mg/L (8h hydraulic retention).
  • Beijing black-odor river: Eliminated foul smell in 30 days (DO boosted from 0.5 to 4.2mg/L).
  • Cost savings: $0.02-0.04/m³ lower OPEX than A²O processes.

B. High-Strength Industrial Wastewater

C. Aquaculture (RAS Systems)

  • Ammonia removal: 1.2kg/m³·day capacity (Norwegian salmon farm data).
  • Self-cleaning carriers: Cut biofilm flushing frequency by 50%.

3. 2025 Technology Frontiers

  • AI Optimization
    • Hangzhou plant: Biofilm thickness sensors reduced aeration energy use by 18%.
  • Net-Zero MBBR
    • Solar-powered systems (e.g., Singapore NEWater plant saves 1,200t CO₂/year).
