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
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.for adsorbing chromium from wastewater. Four different particle sizes of Jift-
