240m³/d Landfill Leachate Treatment System Successfully Shipped to Australia | Major Wastewater Treatment Project Moves Forward

Practical Solutions for Complex Landfill Leachate Wastewater

Landfill leachate is one of the more challenging wastewater treatment applications, as its composition can vary depending on factors such as landfill age, waste composition, rainfall, and operating conditions. The wastewater may contain high concentrations of chemical oxygen demand (COD), ammonia nitrogen, suspended solids (SS), and other pollutants, placing demanding requirements on a reliable landfill leachate treatment system.

For this Australian landfill leachate treatment project, Yimei developed a customized landfill leachate wastewater treatment solution with a treatment capacity of 240m³/day. The system is designed to provide stable biological treatment performance while maintaining reliable operation in a high-load wastewater environment.

With production, inspection, and loading successfully completed, this 240m³/day landfill leachate treatment system has now been successfully shipped to Australia, providing a practical
wastewater treatment solution for landfill leachate.

Challenges of Landfill Leachate Wastewater Treatment

The key challenges of landfill leachate treatment mainly include:

• Complex wastewater characteristics and significant variations in biodegradability
• High COD and high ammonia nitrogen levels
• Significant fluctuations in landfill leachate flow and water quality
• Difficult-to-degrade organic matter
• High requirements for the stability of the biological wastewater treatment system
• Strict wastewater discharge standards

Facing these demanding landfill leachate treatment requirements, Yimei has extensive practical project experience. Previously, we have successfully completed landfill leachate wastewater treatment projects in Cambodia and Canada, developing targeted wastewater treatment process designs based on the specific water quality characteristics, treatment capacity, and discharge requirements of each project.

From Treatment Challenges to a Practical Solution

We use Moving Bed Biofilm Reactor (MBBR) technology as the core biological treatment process. This technology uses suspended biofilm carriers to provide a large and protected surface area for microorganisms. As landfill leachate wastewater flows through the biological treatment zone, microorganisms attached to the carriers break down biodegradable organic pollutants. In addition, continuous aeration and mixing help maintain effective contact between the wastewater, microorganisms, and biofilm carriers, supporting a stable and efficient biological wastewater treatment process.

Why Choose MBBR for Landfill Leachate Treatment?

Treating landfill leachate wastewater involves far more than simply selecting a conventional wastewater treatment process. The treatment system must be capable of handling fluctuating pollutant loads while maintaining reliable and stable biological treatment performance.

MBBR technology offers several practical advantages for landfill leachate treatment:

High biomass concentration: MBBR biofilm carriers provide a large and protected surface area for microbial growth, supporting effective biological treatment.

Stable biological treatment: Microorganisms attached to the carriers can support consistent treatment performance under varying landfill leachate water quality and loading conditions.

Compact system design: MBBR can provide effective biological treatment within a relatively compact footprint, making it suitable for landfill leachate treatment plants where available space is limited.

Flexible process integration: The MBBR process can be integrated with pretreatment, solid-liquid separation, filtration, or advanced wastewater treatment processes according to project requirements.

Customized system configuration: Process parameters, equipment selection, and system configuration can be adjusted according to the actual landfill leachate characteristics, treatment capacity, and discharge requirements.

These advantages make MBBR technology a practical choice for customized landfill leachate wastewater treatment systems, particularly for projects where stable operation, efficient use of space, process flexibility, and reliable treatment performance are important.

240m³/Day Landfill Leachate Wastewater Treatment Plant

The wastewater treatment system designed for this Australian project has a treatment capacity of 240m³/day, equivalent to approximately 63,400 gallons per day (GPD) under continuous operation. The average treatment capacity is approximately 10m³/hour.

Yimei designed the entire landfill leachate wastewater treatment system based on the project's required treatment capacity and specific wastewater treatment objectives. Equipment selection, process configuration, biological treatment requirements, and system layout were all considered as integral components of the overall wastewater treatment solution.

With a treatment capacity of 240m³/day, the system is suitable for large-scale landfill leachate treatment applications, including waste management projects that require continuous and reliable landfill leachate wastewater treatment.

Designed for Large-Scale Landfill Leachate Treatment Applications

For landfill operators, treatment capacity is only one aspect to consider. Factors such as reliable operation, equipment accessibility, process stability, installation requirements, and future maintenance also need to be considered when designing the system.

By combining MBBR biological treatment technology with project-specific equipment configurations, Yimei provides a practical approach to treating complex landfill leachate wastewater, while also allowing the entire system to adapt to the actual conditions of the project.

The Australian project also demonstrates the importance of designing wastewater treatment equipment around actual application requirements, rather than forcing different wastewater characteristics into a fixed standard solution.

Complete Project Delivery from Design to Operation & Maintenance

A successful wastewater treatment project involves far more than equipment manufacturing. From the initial wastewater assessment and process design to equipment production, factory inspection, delivery, installation, commissioning, and ongoing operation and maintenance support, every stage plays an important role in achieving reliable treatment performance.

Yimei’s Integrated Project Support

Wastewater Analysis → Process Design → Equipment Manufacturing → Factory Inspection → Delivery & Shipment → Installation & Commissioning → Operation & Maintenance Support

By integrating these key stages into one project workflow, Yimei helps simplify coordination between different suppliers and ensures that the wastewater treatment system is developed around the project's technical requirements from the very beginning.

Customized Solutions for Different Wastewater Applications

With extensive experience in industrial wastewater treatment equipment, Yimei has developed practical solutions for a wide range of wastewater applications, including landfill leachate, food processing wastewater, slaughterhouse wastewater, brewery wastewater, textile and dyeing wastewater, and other high-strength industrial effluents.

Each project is evaluated according to its wastewater characteristics, treatment capacity, site conditions, and discharge requirements, allowing us to provide a customized wastewater treatment system rather than a one-size-fits-all solution.
