Effective Landfill Leachate Treatment with Advanced Centrifuge Technology

Project Background

This environmental technology company runs a waste management facility where they deal with landfill leachate - basically the liquid that drains from garbage dumps. It's tough stuff to handle because it's loaded with suspended particles and organic compounds that vary depending on what's in the landfill and the weather. They needed better equipment to clean it up enough to meet discharge regulations without breaking their budget.

Processing Challenges

• Landfill leachate contains varying concentrations of suspended solids that fluctuate with seasonal conditions
• High organic content and complex chemical composition make separation difficult with conventional methods
• Strict environmental discharge standards require consistent treatment performance
• Previous treatment methods produced inconsistent results during peak flow periods
• Need for compact equipment due to limited space at the treatment facility
• Requirement for automated operation to minimize labor costs and ensure continuous processing
  
  

  Our Solution

  We looked at their leachate samples and site conditions, then recommended the LW250x1025C centrifuge with a separate polymer dosing system. The combination works well for this type of application - the dosing system helps the particles clump together before they enter the centrifuge, which improves how much solid material gets removed.
