Decentralized Slaughterhouse Water Reuse: Achieving 85% Recycling with Modular Treatment Trains

The Water-Energy Nexus in Meat Processing

Modern slaughterhouses consume 15-40 m³ of water per ton of live weight, with 70% used in cleaning. Rising costs and regulations demand innovative solutions:

• Water scarcity: 58% of global slaughterhouses face supply disruptions

• Effluent surcharges: Up to $8.60/m³ for high-BOD discharge

• Thermal energy waste: 80°C cleaning water loses 65% heat untreated
  Juntai's modular water reuse systems transform wastewater liabilities into assets:

• Closed-loop cleaning: 85% water recycled at 75°C

• Heat recovery: 92% energy capture via plate exchangers

• Zero liquid discharge: Crystallizers produce fertilizer from brine

Breakthrough Technologies for Water & Resource Recovery

1. Intelligent Primary Capture System

Table: Real-time contaminant separation performance

Core Innovations:

• 3D-vibrating screens: Self-cleaning 200μm wedge-wire filters

• Electrocoagulation-flotation: Removes colloidal blood at 0.8 kWh/m³

• Cryogenic fat separation: Freezes FOG at 4°C for easy skimming

2. Thermophilic MBBR for High-Strength Organics

Slaughterhouse effluents contain 3x higher ammonia than municipal sewage. Our solution:

• Bio-block media with Calditerricola satsumensis: Thrives at 55-65°C

• Two-stage nitrogen removal:

  • Aerobic zone: Nitrification at 50 mg NH₄⁺/L·hr

  • Anoxic core: Denitrification via biofilm stratification

• Salinity tolerance: Handles 8,000 ppm Cl⁻ from curing brines
  Performance: 95% COD removal at 12 kg/m³·day organic loading

3. Membrane-Free Concentration Technology

Replacing energy-intensive RO with:

• Forward osmosis (FO): Draw solution recovers 85% water at 0.3 kWh/m³

• Vibratory shear-enhanced process (VSEP): Prevents membrane fouling

• Crystallizer integration: Produces NPK 12-4-6 fertilizer granules

Modular Treatment Train Architecture

Reuse Water Quality:

• Turbidity: <1 NTU

• Pathogens: Undetectable

• Residual chlorine: 0.5-1.0 mg/L

• Temperature: 75±2°C for sanitization
