Why Landfill Leachate Requires a Customized Treatment Process

Landfill leachate forms when rainwater, waste moisture and decomposition liquids pass through municipal or industrial solid waste.

Unlike ordinary domestic wastewater, its composition can change substantially with rainfall, landfill age, waste type and seasonal operating conditions.

Typical Contaminants
High COD and Refractory Organics

Leachate may contain high concentrations of biodegradable and non-biodegradable organic pollutants.

Ammonia Nitrogen

Old landfill leachate can contain high ammonia concentrations that require controlled biological nitrification, chemical treatment or combined processes.

High TDS and Conductivity

Chloride, sulfate and other dissolved salts may accumulate and affect biological treatment and membrane recovery.

Suspended Solids and Color

Fine solids, colloids and dark-colored organic compounds increase filtration and membrane-fouling risks.

Heavy Metals

Depending on the waste composition, leachate may contain iron, manganese, zinc, copper, lead and other metals.

Changing Water Quality

Leachate flow and concentration can increase significantly during rainy seasons, making equalization and flexible operation essential.

Highlighted Statement

There is no universal treatment process for every landfill. The correct system must be selected from the complete water analysis and required discharge or reuse standard.

MBR, STRO, RO and Evaporation Solutions for Different Leachate Conditions

Guanya selects the treatment route according to the landfill age, contaminant loading, biological treatability, salinity, membrane-scaling risk and concentrate-disposal conditions.

Typical Process Flow

Leachate Collection
→ Screening and Equalization→ pH Adjustment and Chemical Pretreatment→ Biological Treatment / MBR→ STRO, NF or RO Treatment→ Optional Advanced Oxidation→ Optional Concentrate Evaporation→ Reuse or Compliant Discharge

Solution 1：MBR Biological Treatment

Suitable for:

Young or intermediate landfill leachate containing relatively biodegradable COD and high ammonia nitrogen.

Typical process:

Equalization → pH Adjustment → Biological Treatment → Nitrification and Denitrification → MBR → Disinfection

Main functions:

Reduce biodegradable COD and BOD/Reduce ammonia nitrogen/Separate biological sludge from treated water/Produce stable feed water for downstream NF, RO or STRO/Reduce membrane fouling in the advanced-treatment stage
Solution 2：STRO or RO Membrane Treatment

Suitable for:

Leachate requiring lower dissolved salts, color, residual COD and other dissolved contaminants.

Typical process:

Pretreatment → Cartridge Filtration → STRO/NF/RO → Permeate Tank → Concentrate Management

Main functions:

Reduce dissolved salts and conductivity/Remove residual color and dissolved contaminants/Produce higher-quality treated water/Support approved reuse or discharge applications/Concentrate pollutants for separate management

STRO can be considered for high-fouling wastewater where a more open membrane flow path is required. Conventional spiral-wound RO may be used when pretreatment provides suitable and stable membrane-feed quality.

Solution 3：High-Recovery and Concentrate Treatment

Suitable for:

Projects requiring lower liquid-disposal volume or further treatment of membrane concentrate.

Typical process:

MBR Pretreatment → Staged STRO/RO → Concentrate Tank → Low-Temperature Evaporation

Main functions:

Recover additional reusable water/Reduce concentrate volume/Separate condensate from concentrated pollutants/Reduce external liquid transportation/Support site-specific minimal-liquid-discharge strategies/Technical Qualification

Final recovery rate, membrane selection and treated-water quality must be confirmed after evaluating COD, ammonia, TDS, hardness, silica, metals, temperature and concentrate-scaling potential.
