Slaughterhouse Wastewater Solutions: Achieve 99% FOG Removal & Zero Violations
The Unique Contaminant Profile of Slaughterhouse Effluent
Slaughterhouse wastewater presents extreme challenges distinct from municipal sewage:
-
High fat/oil content (2,000-10,000 mg/L FOG) causing pipe blockages and biological inhibition
-
Blood residues increasing BOD up to 8,000 mg/L and attracting pathogens
-
Protein-rich organics decomposing into toxic ammonia (NH₃ >200 mg/L)
-
Pathogen loads (E. coli, Salmonella) 100x higher than domestic wastewater
Without specialized treatment, these contaminants trigger ecosystem damage and regulatory penalties. Our data shows 78% of slaughterhouses face non-compliance fines exceeding $120,000/year due to inadequate treatment.
Breakthrough Treatment Process for Complex Slaughterhouse Waste
1. Pre-Treatment: Fat & Solids Elimination
Table: Performance comparison of primary treatment technologies
Technology | FOG Removal | TSS Reduction | Footprint | Operational Cost |
---|---|---|---|---|
Traditional DAF | 65-75% | 70% | 100% | $0.35/m³ |
Screw Press + Heated Dissolved Air Flotation (H-DAF) | 92-98% | 95% | 60% | $0.18/m³ |
Juntai Bio-Coagulation | 99%+ | 98% | 40% | $0.12/m³ |
Juntai Solution:
-
Thermally-enhanced DAF: Operates at 45°C to liquefy solidified fats
-
Enzymatic breakers: Lipase/protease blends emulsify blood-fat complexes
-
Self-cleaning Drum Filters: Capture hair/feathers with 500μm screens
2. Biological Treatment: Handling Nitrogen & Organics
Slaughterhouse effluents require staged biological processes:
-
Anaerobic Mbbr: Removes 85% COD while generating biogas (0.45m³/kg CODremoved)
-
Hybrid MBBR-AS system: Combines biofilm resilience with activated sludge flexibility
-
Psychrophilic adaptation: Maintains 80% nitrification at 8°C for unheated facilities
Key innovation: Bio-block media with Thiothrix enrichment prevents filamentous bulking from sulfur compounds.
3. Tertiary Polishing: Pathogen & Nutrient Control
-
Tube settler clarifiers: Achieve 10 NTU effluent with hydraulic loading 12 m³/m²·h
-
Electrochemical disinfection: 5-log pathogen kill without chlorine byproducts
-
Struvite recovery: Captures 85% phosphorus as fertilizer-grade crystals
Proven Process Flow for Compliance & Reuse
Output Quality:
-
BOD: <20 mg/L (99.2% removal)
-
NH₃-N: <5 mg/L
-
Fecal coliform: <100 CFU/100mL
-
Water recovery: 70% reusable for washing
