Nowadays, environmental pollution has become a major concern; requiring action to solve this problem that threatens human beings, different ecosystems, fauna and flora. Effluents from domestic and industrial discharges are a main source of pollution given their contaminant load; among the main pollutants generated by industrial activities are heavy metals (Lead, Zinc, Copper, Chromium...). Due to their non-biodegradable nature, these elements pose eco-toxicity problems of particular concern. As part of the contaminated ecosystems depollution, several techniques have been adopted for the remediation and the elimination of contaminants then encouraging results have been obtained through the new conception of "Phyto-epuration". It is a technique that relies on plants to remove or transform pollutants into less toxic compounds, so it is ecologically friendly, economically profitable and technically easy to apply. Our study consists in creating filters planted with macrophytes (Typha latifolia and Cepyrus Payrus) and a bare filter, then filling them with wastewater of industrial origin. The objective is to highlight the potential of plants to treat wastewater and particularly to remove heavy metals. The results obtained show an elimination of Lead with 97% and 96% and Zinc with 94% and 92% respectively for Typha latifolia and Cepyrus Payrus for a residence time of 15 days. Therefore, these results confirm the interest of using the planted filters in the context of industrial wastewater treatment.
