Pig Farm Biogas Slurry Treatment Case Study

Title

Case Study: Pig Farm Biogas Slurry Treatment – From Dark Raw Slurry to Clear Ozone-Treated Water

Subtitle

An integrated wastewater treatment solution for deodorization, decolorization, and pathogen disinfection in pig farms.

Introduction

Pig farm biogas slurry is often highly contaminated with organic matter, suspended solids, color, odor, and pathogens. If left untreated, it can create serious environmental risks, including odor complaints, soil and water pollution, and pathogen transmission.

Our integrated treatment system combines solid-liquid separation, biological treatment, filtration, and ozone disinfection to address these challenges in one continuous process.

Water Sample Comparison

• Raw Biogas Slurry: Dark brown, high in organic load, suspended solids, odor, and pathogens.
• Intermediate Treated Water: Lighter in color, partially decolorized, with reduced odor and organic load.
• Final Ozone-Treated Water: Clear, low color, odor-free, and effectively disinfected.

Core Treatment Process

1. Solid-Liquid Separation Separates large suspended solids from raw biogas slurry, reducing organic load and protecting downstream equipment.
2. Biological Treatment Breaks down dissolved organic matter and reduces COD, BOD, and nutrient levels in the wastewater.
3. Filtration Removes fine particles and residual suspended solids, improving water clarity before disinfection.
4. Ozone Disinfection Ozone provides strong oxidation and disinfection, helping to remove odor, decolorize the water, and kill bacteria, viruses, and parasites.

Key Advantages

✅ Effective deodorization
✅ Visible decolorization
✅ Strong pathogen disinfection
✅ Reduced organic load
✅ Improved water reuse potential
✅ Stable and automatic operation

Conclusion

This trial result demonstrates that an integrated ozone-based system can transform dark, odorous pig farm biogas slurry into clear treated water. It is a reliable solution for pig farms aiming to improve wastewater management, reduce environmental impact, and meet discharge and reuse requirements.
