Transform complex landfill leachate into manageable, treatable water
LeachOxy™ is an integrated treatment approach developed to address the challenging mixture of organic pollutants, heavy metals, colour, odour and other contaminants found in landfill leachate.
Landfill leachate forms when water passes through deposited waste and carries dissolved and suspended contaminants into the collection system. Its composition can vary substantially with landfill age, waste type, rainfall and operating conditions. LeachOxy™ combines oxidation, catalytic treatment, pH conditioning, filtration and adsorption to support contaminant reduction before discharge or downstream membrane treatment. The brochure references several treatment components—including MagnetSorb™, OXYDES-P™, OrganoSorb™ and PMOF-coated ActiveSorb-CX™—that may be configured according to the analysed leachate composition and required effluent quality.
Multiple treatment barriers / One engineered leachate solution
Engineered for complex and variable wastewater
LeachOxy™ treatment components can be configured for leachate pretreatment, advanced polishing, membrane protection and the treatment of selected industrial wastewaters.
Landfill Leachate Treatment
Supports the reduction of suspended solids, colour, odour, organic loading and selected inorganic contaminants in landfill leachate.
Heavy-Metal Separation
Conditions may be created for the adsorption or precipitation of metals such as lead, cadmium and mercury before solids separation.
Industrial Wastewater Treatment
Applicable to selected industrial wastewaters containing difficult organic compounds, metals, colour or variable pH.
Membrane Pretreatment
Reduces selected foulants and suspended contaminants before reverse-osmosis or other membrane-treatment stages.
PFAS & Micropollutant Polishing
PMOF-coated adsorbents are proposed for capturing selected PFAS and other persistent contaminants, subject to compound-specific validation.
Environmental Remediation
Supports treatment programmes designed to reduce pollutant migration and protect surrounding soil, surface water and groundwater.
Suggested Treatment Sequence
Step-by-step multi-barrier workflow from leachate characterisation to final verification and membrane treatment.
LeachOxy™ Treatment Stages
| Stage | Process Description |
|---|---|
| Stage 1 — Leachate Characterisation | Measure pH, conductivity, alkalinity, COD, BOD, TOC, ammonium, metals, colour, suspended solids, PFAS and other site-specific contaminants. |
| Stage 2 — Conditioning & MagnetSorb™ | Condition the leachate, support metal precipitation and reduce suspended contaminants through catalytic-media filtration. |
| Stage 3 — Oxidation | Apply a compatible oxidizing process to transform selected organic contaminants. Oxidant demand and residual oxidant must be monitored. |
| Stage 4 — OrganoSorb™ Adsorption | Adsorb residual dissolved organic compounds and oxidation by-products that remain after primary treatment. |
| Stage 5 — ActiveSorb-CX™ / PMOF Polishing | Provide a final adsorption barrier for selected micropollutants, PFAS or other contaminants identified during water analysis. |
| Stage 6 — Final Verification / Membrane | Confirm that treated water meets intended discharge, sewer-acceptance, reuse or membrane-feed requirements. |
Four complementary technologies / For advanced leachate treatment
Conditioning, Catalysis and Filtration (MAGNETSORB)
MagnetSorb™ is presented as a glass-coated catalytic filtration medium that supports pH conditioning, turbidity reduction and the adsorption or precipitation of selected contaminants.
Advanced Oxidation Support (OXY-TREATMENT)
The oxidation stage is designed to transform susceptible organic pollutants and improve their removal during downstream filtration or adsorption.
Organic-Contaminant Adsorption (ORGANOSORB)
OrganoSorb™ is identified as a downstream treatment stage for adsorbing residual organic contaminants after initial conditioning and catalytic treatment.
Advanced Micropollutant Polishing (PMOF-ACTIVESORB)
PMOF-coated ActiveSorb-CX™ is proposed as a high-surface-area polishing medium for selected heavy metals, organic compounds, PFAS, 6PPD-related compounds and microplastics.
Science & Technology
LeachOxy™ combines several physical and chemical mechanisms because no single treatment process can reliably address every contaminant present in landfill leachate.
- pH Conditioning and Precipitation – MagnetSorb™ conditions acidic leachate and supports pH stabilisation. Increasing pH under controlled conditions reduces the solubility of certain metals and promotes precipitation.
- Catalytic Oxidation – Catalytic surfaces support oxidizer activation and accelerate reactions with susceptible organic compounds, breaking large or persistent molecules into smaller intermediates.
- High-Surface-Area Adsorption – Porous filtration and adsorption media provide binding sites for selected dissolved contaminants based on pore structure, surface chemistry and contact time.
- Advanced Polishing – PMOF-coated activated carbon provides a final polishing barrier designed to increase available binding sites for selected metals, persistent organics and PFAS.
MagnetSorb™ & Operational Guidance
Media highlights, operational considerations, and safety guidance for integrated leachate treatment.
MagnetSorb™ Technology Highlights
- Glass-coated granular media offering high-surface-area filtration and adsorption
- Potential pH-conditioning capability and support for heavy-metal precipitation
- Turbidity and suspended-solids reduction with odour-control support
- Catalytic oxidation support with regeneration proposed via diluted OXYDES-P™ solution
Operational & Safety Considerations
- Confirm required empty-bed contact time through pilot testing; clarify bed-volume definitions prior to final design.
- Monitor influent/effluent contaminant concentrations, pH, pressure drop, flow rate and breakthrough.
- Prevent oxidants from entering incompatible downstream adsorption stages; ensure complete chemical compatibility.
- Characterise spent media and treatment sludge before disposal as hazardous waste according to local regulations.
