Landfill leachate and concentrate

      DTRO was originally developed for landfill leachate treatment. Through years of applications, improvement and continuous optimization, Sotec has developed standardized single-stage and double-stage integrated equipment based on leachate treatment scales: 50m³/d, 100m³/d, 200m³/d, 300m³/d.

      Sotec Environmental offers complete leachate and concentrate treatment solutions.

Pretreatment + MBR + single-stage DTRO process

Two-stage DTRO process

TLD leachate concentrate full treatment process

Scope of application:

More suitable for projects with treatment scale above 200m³/d

Applicable to the treatment of all incineration plant leachate as there is an anaerobic system at the front end

Scope of application:

Small and medium-sized projects of 200m³/d and below

Suitable for full-cycle water quality of landfills, especially aging landfills

Especially suitable for treatment of leachate with significant changes in water quality or poor biochemical properties

Particularly suitable for extremely cold areas (where biochemical processes cannot proceed normally)

Scope of application:

Leachate of old landfill

High-salinity landfill leachate

Concentrate produced during DTRO treatment
