Dynatec Systems has built on its water treatment experience that began in the 1970’s using membranes with rugged industrial reliability to produce Ultrafiltration (UF) and Reverse Osmosis (RO) systems. Since 1999, Dynatec Systems’  experience with Membrane Bioreactors (MBR)s has developed many unique process improvements necessary for industrial wastewater applications. Dynatec successfully uses Ultrafiltration (UF), Membrane Bioreactor (MBR) and Reverse Osmosis (RO) for landfill leachate applications.

Various Landfill Leachate Treatment Requirements

The requirements for landfill leachate treatment can vary, depending on the discharge requirements, and the contaminants present.

Landfill leachate is generally characterized by:

Landfill Leachate Treatment Options

Dynatec can provide the Membrane Bioreactor (MBR) option, which is an aerated biological mixed liquor process operating at very high solids concentrations.  Some of the advantages are:

Typical results from a Membrane Bioreactor (MBR) operation at a landfill are as follows:

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

The system also produces bio-sludge, which depending on the requirements, can be dewatered for disposal, or disposed of as a liquid sludge.

Alternative treatment options are also available and may include:

The two effluent streams from a Reverse Osmosis system are:

This can normally be re-injected into the landfill, but its long-term effects on leachate concentrations should be considered.


The Membrane Bioreactor (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 Reverse Osmosis (RO) treatment.

The Reverse Osmosis (RO) permeate can then be used for other non-potable purposes, such as:

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