Our study is followed by an analysis of raw water quality and treated in the experimental test. The results of the main parameters revealed values that meet the requirements of the WHO and Algerian standards for phytopurification. The bacteriological analyzes confirm a system efficiency in the abatement of total coliforms and fecal coliforms. The results we have obtained clearly show the effectiveness of such a system for the treatment of wastewater. Pollution abatement achieved: 96.66% removal of COD; 95.83% of BOD5; 91.66% of the total nitrogen, 84.62% of the total phosphorus; 90.87% of the total Coliforms and 96.31% of the thermo tolerant Coliforms. The results obtained show that the quality of the water after treatment is much higher than that taken at the entrance of the basins. The treated water can partially meet the needs of crops and allow the economy of mineral fertilizers accordingly. The treatment of sewage by phytopurification is economical, maintenance is reduced compared to "conventional treatment plants", and the installation is energy saving. We recommend that this experiment be expanded for wastewater treatment at SCANTOGO.
