Landfill Leachate Treatment
Integrated treatment concepts for variable, concentrated landfill leachate and associated wastewater streams.
Leachate composition and variability drive the process
Age of landfill, rainfall, ammonia, organics, salinity and suspended solids affect pretreatment and membrane selection.
Final equipment and process selection require project-specific review.
Design for a complex and changing wastewater
PALLIND discusses membrane and integrated treatment routes for landfill leachate, including pretreatment, high-ammonia treatment, membrane separation and concentrate management. The final route requires current analytical data and discharge or reuse objectives.
Feed conditioning
Assess suspended solids, hardness, organics and biological or chemical pretreatment needs.
Ammonia and membrane treatment
Review ammonia-removal and membrane separation steps against the actual leachate profile.
Concentrate management
Coordinate residual concentration, recovery and disposal with the complete water balance.
Information needed for a useful technical discussion
Share the available operating data and project objective. PALLIND can then discuss a suitable treatment route and the information still required for design.
- Recent and historical leachate analysis with seasonal variation.
- Average and peak flow plus rainfall influence.
- Ammonia nitrogen, COD, salinity, hardness and suspended solids.
- Required discharge or reuse target.
- Existing plant, footprint, residuals and concentrate disposal route.
Early-stage application questions
Can a treatment route be selected from the industry name alone?
No. A useful selection requires verified water analysis, flow, operating conditions and the required product-water, reuse or discharge target.
Are treatment results guaranteed by this page?
No. Performance must be evaluated against a confirmed design basis, equipment selection and supporting project documents.
