Background
The treatment of the leachate of discharge by the classic ways of purge of waters shows itself :
- very difficult due to their low biodegradability and especially the presence of contaminants;
- harmful to traditional techniques of nitrification-denitrification.
The ability of local or regional treatment is also often absent and alternative techniques for incineration are very expensive.
The use of technologies that combine, for example, a suitable biological treatment with microalgae adapted to leachate may be entering a completely innovative solution in a sustainable development policy.
