Landfill leachate treatment systems with Membrane Bioreactors (MBR)s have developed many unique process improvements for industrial wastewater applications. Dynatec successfully uses Ultrafiltration (UF), MBR and Reverse Osmosis (RO) for landfill leachate applications.

Landfill leachate treatment requirements

Treatment can vary, depending on the discharge requirements, and the contaminants present

Landfill leachate is characterized by:landfill leachate treatment

The MBR option: an aerated biological mixed liquor process operating at very high solids concentrations. 

The advantages are:

Typical MBR results in landfills: 

Parameter BOD COD TSS Ammonia
Influent 500 4000 150 1000
Effluent <5 800 <5 <1
% Removal >99% 80% >96% >99%

The system produces bio-sludge dewatered for disposal, or disposed of as a liquid sludge.

Alternative landfill leachate treatment options: 

The two effluent streams from a RO system are:

This can be re-injected into the landfill.  Its long-term effects on leachate concentrations should be considered.


The MBR process provides the highest possible levels of organic removal with essentially zero suspended solids in the effluent. This is the ideal feed system for RO treatment.

RO permeate can be used for other non-potable purposes:

Dynatec membrane treatment systems have successfully provided outstanding performance in many landfill leachate applications. Considerations for this technology include:
