LVFENG’s Three-Step Process Reduces Slaughterhouse Wastewater Treatment Costs to Under $0.45 per Ton
2025-04-25
Industry Challenges: Why Are Slaughterhouse Wastewater Treatment Costs So High?
Slaughterhouse wastewater contains high levels of oils, blood, and viscera residues, with COD levels reaching 3,000–5,000 mg/L. Traditional treatment methods require multiple stages, leading to high investment, energy consumption, and complex sludge disposal. For example, a plant processing 2,000 tons daily faces treatment costs of $0.63–$0.83 per ton, with chemicals and electricity accounting for over 70% of the costs.

LVFENG’s Three-Step Solution: Cost Reduction and Efficiency Enhancement
With 15 years of industry experience, LVFENG has developed a “grease trap + Dissolved Air Flotation (DAF) + SBR” process to address these challenges:
With 15 years of industry experience, LVFENG has developed a “grease trap + Dissolved Air Flotation (DAF) + SBR” process to address these challenges:
- Grease Trap Pretreatment: Efficient Oil Removal
Using inclined plate grease trap technology, this step rapidly separates floating oils and suspended solids, achieving over 85% oil removal and reducing the load on subsequent treatments by 30%. - DAF Process: Precise Emulsion Breaking and Chemical Savings
A micro-nano bubble DAF unit is used, increasing emulsified oil removal to 95% and reducing chemical usage by 20%. - SBR Bio-Treatment: Low Sludge Production and Stable Performance
Through intermittent aeration and temporal controls, this process accommodates the fluctuating quality of slaughterhouse wastewater, ensuring a stable COD removal rate of over 95%.
Client Success Story: Achieving Low Costs and High Standards
A large-scale slaughterhouse upgrade project highlights LVFENG’s effectiveness. Previously, the client faced high treatment costs of $0.63 per ton and frequent COD exceedances (＞150 mg/L), risking environmental penalties. LVFENG’s solution—expanding the grease trap, upgrading the DAF system, and optimizing SBR aeration timing—delivered significant results. The treated water now consistently meets the first-grade standards (COD ≤80 mg/L) of the “Meat Processing Industry Water Pollutant Emission Standards.” The cost has been reduced to under $0.45 per ton, with annual savings exceeding $280,000.
