    Solid waste from olive oil production is a significant problem in Mediterranean countries, for example Palestine

    produces annually from12,000 to 14,000 tons. In this study

     

    Jift, a burned solid olive waste, which is known to be

    environmentally hazardous; was used in environmental protection. This study investigated the applicability of using

    Jift

     

    were selected and tested for their chromium adsorption capacity from aqueous solutions. The adsorption equilibrium results showed that  Jift  with particles size 425 μm diameter achieved the highest adsorption capacity. The adsorption capacity was attributed to the surface characteristic as well as the surface area of

    Jift.  The adsorption isotherms were represented by Langmuir and/or Freundlich isotherms. The removal of chromium by Jift  adsorption was successfully achieved. Moreover, utilization of Jift  was proposed for the preparation and enhancement activated carbon. The cost estimation of this full utilization of the Jift  in extracting olive oil, wastewater treatment and producing safe fuel was performed and found to yield an IRR value of 12%. It is evident from the experimental results and feasibility studies that the use of Jift chromium removal seems to be technically feasible, environmentally friendly, and economically attractive for the treatment of Cr-contaminated wastewater.
