The objective of this study is to show the potential of Typha latifolia in the Purification performance of wastewater in the region of El Oued (southeast of Algeria). The pilot scale consists of two beds of plastics, filled with gravel and sand. One was planted saplings Typha latifolia at 36 stems/m², the second was not planted serves as a control (witness). The results show good yields for suspended solids and organic pollution, removal rates are 96,76% for (SS) 89,92% for the Chemical Oxygen Demand (COD) and 87, 98% for biochemical oxygen demand in 5 days (BOD₅). There is a clear increase in the concentration of dissolved oxygen (DO). The system effectively removes nitrite (88.84%), nitrate (91.20%), and orthophosphate (93.12%).
