The treatment of wastewater is a problem that does not date from yesterday. This sector remains the so-called "pollution always and still in the headlines", despite the constant evolution of treatment techniques and the presence of standards in force and laws adjusted to the service of environmental protection. Considering that wastewater treatment is considered as an incomplete cure, it is necessary to act by resorting to a green, ecological and economic way, that of the treatment by macrophytes. This technique is a real alternative to traditional methods and gives more reliable results in terms of sanitation.
