We conducted this study at the national sanitation office of the wilaya of Khenchela, Plant material (Typha latifolia), used in the pilot plant was selected on the basis of plants species found around the releases of wastewater. The results show that the filters planted of Typha, ensures a good abatement of all tested parameters. We can conclude that the Treatment with filters planted at macrophytes seems to be an effective alternative and quite well suited to wastewater at pollution load variable.frThesis
