Landfill Leachate Treatment Solutions
Landfill leachate is one of the most complex types of wastewater, characterized by high COD, ammonia nitrogen, heavy metals, and variable composition over time.
Its treatment requires a combination of chemical conditioning and process optimization to ensure stable performance and compliance.
Ecozon Chemicals provides advanced chemical solutions to support coagulation, flocculation, and pretreatment processes in landfill leachate treatment systems.
Key Treatment Challenges
- Extremely high COD and ammonia nitrogen levels
- Complex and variable wastewater composition
- Presence of refractory organic compounds
- Poor biodegradability in certain stages
- Difficult solid-liquid separation and sludge handling
Our Treatment Approach
Effective landfill leachate treatment requires a tailored and flexible chemical strategy:
- Coagulation (PAC / PFS)
Reduces organic load and improves removal of suspended solids - Flocculation (PAM)
Enhances separation efficiency and improves settling performance
Pretreatment Optimization
Supports downstream biological or membrane processes
👉 Our solutions are designed to adapt to changing leachate characteristics across different landfill stages.
Application Scenarios
- Landfill leachate treatment plants
- Municipal solid waste landfill sites
- Waste transfer station wastewater
- Pre-treatment before biological or membrane systems
Recommended Product Selection
| Treatment Stage | Recommended Product |
