Different coastal sands of the city of El Jadida are used to filter wastewater from a cardboard manufacturing plant combined with fly ash and bottom ash (by-products of a local power plant). The performances of five matrices of these elements are compared in infiltration-percolation in vertical columns. The study of particle size sand is performed beforehand. The chemical and mineralogical composition of fly ash and bottom ash are produced by X-ray fluorescence and X-ray diffraction respectively. The wastewater samples were collected during a complete cycle of production of the cardboard. The heavy metals content before and after filtration was obtained by atomic emission spectrometry with inductively coupled plasma (ICP-AES). The parameters analyzed were: total suspended solids (TSS), organic matter COD, BOD₅, the potential hydrogen pH and heavy metals (iron, zinc and arsenic). The results are very conclusive and respect the essence of control required by Moroccan regulations (law 1606-06) related to discharges from the papermaking and cardboard industry.
