Adsorption studies of zinc (Zn²⁺), cadmium (Cd²⁺) and nickel (Ni²⁺) from aqueous solutions on corncob (CC) and granular activated carbon (GACC) were carried out. A batch pattern was used to determine the kinetics as well as the adsorption isotherm parameters. The obtained results using either CC or GACC separately were found to be matched with the Langmuir isotherm model. Furthermore, the breakthrough study was conducted using CC, and GACC. This study was extended with wetland technology for the purification of greywater.The main objective of this study the enhancement of the sedimentation tank by coagulants materials (ferric chloride aided with lime) was followed by a hybrid-constructed wetland. The evaluation three hydraulic retention times (HRT) were 24, 48, and 72 h.The obtained results showed the quality of the effluent at 72 h was found to be complying with the EEAA limits (2nd) for treated effluent reuse.
