MBBR + Tube Settler Hybrid System: JUNTAI’s Answer to Chemical Wastewater Sludge Bulking
The Sludge Bulking Crisis in Chemical Wastewater
High COD (5,000-10,000 mg/L) and nutrient imbalance in industries like pharmaceuticals and petrochemicals trigger sludge bulking, causing:
⚠️ 30-50% loss in treatment capacity
⚠️ Rising disposal costs from poor dewatering
⚠️ Regulatory penalties for effluent violations
JUNTAI Hybrid System: 3-Step Control Mechanism
1️⃣ Biofilm Thickness Management
-
Mbbr Carriers with 12mm ridges limit biofilm growth to 2-3mm (ideal for suppressing filamentous bacteria)
-
Automatic biofilm detachment via controlled aeration pulses
2️⃣ HRT Optimization
-
MBBR zone: 8-hour HRT ensures complete BOD removal
-
Tube Settler zone: 1.5-hour HRT with 55° tilt angle captures 95% of detached biomass
3️⃣ Intelligent Sludge Recycling
-
Dynamic return ratio (30-70%) based on real-time SVI monitoring
-
Reduces secondary clarifier overload risk
