Olive mill wastewater (OMW) is nowadays considered a serious environmental problem, especially within the Mediterraneanregion. With this in mind, water shortages are also a very serious and prevalent concern in third world countries. *e aim of thisstudy is to investigate the feasibility of using Jordanian bentonite, a simple and natural clay, as a possible adsorbent to decrease thenegative characteristics of raw OMW, as an approach to the development of a methodology that addresses the OMW problemwithout affecting freshwater resources. *e purified bentonite was activated by sodium ions at room temperature. FTIR, XRD,TGA, and BETsurface area measurements were performed.OMWwas contacted with both purified and activated bentonite in thebatch technique to figure out the optimum parameters for the adsorption process. Physiochemical parameters of OMW weremeasured before and after treatment. *e maximum adsorption qm was found as 8.81 mg/g at 323K for the total phenoliccompounds. *e Langmuir and Freundlich models were utilized to describe the equilibrium isotherms and both models fit well.*e parameters of thermodynamic show that the adsorption process was feasible, spontaneous, and endothermic in nature. *esepromising results along with the sodium activation of bentonite significantly improve bentonite’s adsorption capacity.
