Introduction: Why Are Traditional Processes So Expensive?

Conventional activated sludge systems (A²/O, SBR) suffer from 3 major cost drivers:

  1. Large footprint → High civil construction cost
  2. High energy use → Aeration + recirculation = 60% of OPEX
  3. High sludge yield → Disposal fees rising 10%+ annually

MBBR (Moving Bed Biofilm Reactor) technology, powered by high-performance media, delivers smaller volume, higher efficiency, and lower total cost.

3 Ways MBBR Media Reduces Costs (Data-Backed Charts)

1️⃣ 5–10x Higher Volumetric Loading → 70% Smaller Reactor Volume

ProcessVolumetric Load (kg COD/m³·d)Reactor Volume (m³/ton COD)Civil Cost
Conventional Sludge0.5–1.01.0–2.0100%
MBBR5–100.1–0.3↓70%

Real Case: Food factory, 500 m³/day

  • A²/O: 800 m³ tank
  • MBBR Retrofit: 200 m³ → Saved ¥1,200,000 in construction

Grok can make mistakes. Always check original sources.

2️⃣ 30% Higher Aeration Efficiency → ¥0.3–0.5/ton Power Savings

MBBR media density ≈ water (0.97 g/cm³) → tiny bubbles drive full fluidization. Oxygen Transfer Efficiency (OTE) reaches 28–35% (vs. 18–22% in traditional systems).

ItemConventionalMBBRSavings
Air Volume (m³ air/m³ water)25–3015–18↓40%
Power Cost (¥/ton water)0.8–1.20.4–0.6↓50%

Case: Dyeing plant, 1 million tons/year Annual power savings: ¥600,000

3️⃣ 60% Less Sludge → ¥200,000+/year Disposal Savings

Long sludge age (>20 days) in MBBR biofilm → sludge yield drops to 0.05–0.1 kgSS/kgCOD (vs. 0.4–0.6).
