Treatment of leachate from landfills

The landfill leachate is the highly contaminated aqueous effluent that is generated as a consequence of (1) rainwater percolation through wastes, (2) the liquid fraction contained in the waste itself, and (3) the liquid generated during the biological processes occurring naturally in the waste matter.

Landfill leachate characteristics and composition differ significantly from site to site and along the time, according to several factors, such as the landfill type, the climate and geographical situation, and the landfill age. It contains a complex mixture of organic substances (biodegradable and refractory), ammonia-nitrogen, heavy metals and chlorinated organic and inorganic salts.

The discharge limits vary significantly from one landfill site to another. Apart from the more or less stringent legislation in the different countries, the most significant changes are related to the receiving water body:

Challenges for leachate treatment

Management of MSW – and leachate as a result – constitutes a major environmental, economic and social problem worldwide. Since the waste volume is growing fast globally, reuse and recycling policies applied more and more each day. Moreover, stringent environmental regulations with more demanding discharge limits are being imposed.

The great challenge of landfill leachates lies in their varying composition, high concentration of contaminants and their toxicity. Landfill leachate can be compared to the most complex industrial wastewaters, with a significant amount of recalcitrant organic matter that hampers the implementation of conventional biological treatments. The high concentration of ammonia and salts can also be challenging issues in these cases.

Landfill leachate can be compared to the most complex industrial wastewaters, with a significant amount of recalcitrant organic matter that hampers the implementation of conventional biological treatments. The high concentration of ammonia and salts can also be challenging issues in these cases.

Tubular UF solutions for leachate

The high variability of leachate’s volume and composition, not only from site to site but also during the landfill lifetime, also constitutes an important challenge. The composition of the leachate can change from month to month, seasonally, and of course, during the life of the site. As a result, robust, flexible, and adaptable processes and technologies are increasingly sought. The fact that the implemented technology is easily upgradable during the landfill’s lifetime is also a common requirement by the operators.

Membrane filtration technologies are being increasingly applied for landfill leachate treatment, as long as they allow addressing the most challenging requirements in terms of effluent quality and process reliability.  With more than 400 references worldwide, Berghof tubular UF is known to be an optimum technology for the most robust and efficient leachate management.

Berghof membranes can be installed in several process configurations, depending on the type of contaminants and the discharge requirements. The MBR process is the most widely applied, both as a standalone process or followed by a post-treatment for recalcitrant COD and salts removal (NF, reverse osmosis, etc.). In small installations and when the leachate presents very low biodegradability (e.g. inert waste landfills) direct UF is often the choice, typically followed by an RO step for removing the low molecular weight compounds and salinity.

Applications of tubular UF membrane technology in landfill leachate

MBR | Leachate Treatment

Biological processes are the core of the treatment process in most of the cases. In this way, organic matter and nitrogen are eliminated and released as CO2 and N2 gases.

Direct UF | Leachate treatment

Berghof tubular UF membranes can be used for leachate treatment as a direct filtration step, typically followed by nanofiltration, reverse osmosis or activated carbon adsorption.
