Leachate treatment

Nomado offers leachate treatment systems.

A solution adapted to specific requirements.


Leachate is effluent that is produced when stormwater run-off comes into contact with decomposing waste that is landfilled. This leachate mainly contains nitrogen-based (ammonia), carbon-based (COD, organic waste) and heavy metal-based pollutants.
Generally, leachate is stored in tanks at these landfill sites before being treated in-situ or removed from the site.

The nature and composition of waste, the conditions in which it has been landfilled, the site’s operating methods or the weather conditions to which the waste is exposed greatly influence the nature and the quantity of leachate produced. Another difficulty: the composition of leachate varies considerably over time.

This complexity and diversity require us to first describe the properties and quantity of the effluent to be treated (load, volume, flux, toxicity). This characterisation exercise must also be undertaken over time in order to ascertain the variations in quantity and quality in order to determine the suitability of the treatment process envisaged.

Our approach

We offer suitable treatment units be it for a pretreatment solution if the site has a discharge agreement with a wastewater treatment plant, or for treatment before discharge into the natural environment, depending on the characteristics of the effluent as well as discharge authorisations.
The best treatment solution is often a combination of a series of several, very different processes in which we are expert ((physico-chemical, biological treatment (aeration, oxidation, with ozone), membrane treatment)).

Nomado has significant experience in studying, sizing and constructing these treatment systems. We can assist you.

The solutions that we offer adjust extremely well to variations in the quality of the water to be treated and the quantity of the load that it contains. Our treatment units are integrated into sea containers or mounted on SKIDs thereby reducing production times, installation times on site and civil engineering costs.
Sheet metal work and welding of the hydraulic structures are performed directly inside the container. Waterproofing is ensured by a seal made of special coatings that constitutes a perfectly monolithic block. It prevents water from coming into contact with the structures. The Coatings’ properties are always chosen in accordance with the project’s specifics (Health compliance certificate, WRAS, aggressiveness of reagents or water, etc.).
