It is a strategic target now to reuse treated industrial waste water for washing, irrigation etc., to efficiently manage and maximize Sudanese's water resources. The aim of the present work was to study the performance of natural zeolite (scolecite) for removing heavy metals from industrial waste water. Natural zeolite deposit sample was collected from Bayooda desert. Natural zeolite used (scolecite) was characterized by XRD, XRF, SEM and FTIR instruments. The physical properties (pH, EC, TDS, COD, BOD, total hardness) and chemical properties (Ni2+, Pb2+, Zn2+, Cd2+, Fe3+, Cr3+) of the collected industrial waste water samples were investigated. Zeolite sorbed around 95.8, 88.1, 48, 50, 19.7 and 99.9% of Ni2+, Pb2+, Zn2+, Cd2+, Fe3+ and Cr3+ metal concentrations respectively. According to the percentage sorption values, the selectivity sequence of studied metals by natural zeolite can be given as Cr3+>Ni2+
