The level of the environmental impact of olive oil production in Palestine was evaluated by measuring the parameters: pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), total dissolved solids (TDS), the concentration of fat; oil, and grease (FOG), phenols, electric conductivity (EC) total phosphorus (T-P), and total Kjeldahl nitrogen (TKN, and compared with the Jordanian standard values. The results show that the value of these parameters are too high. A local survey has also been conducted by designing a questionnaire that covers oil production yield, water consumptions in olive washing and in oil recovery, wastewater generation relative to olive processed and oil generated, and solid waste product: The data were collected from 92 local olive oil mills, which were analyzed and organized according to the investigated parameters, and categorized according to local selected areas in the West Bank such as Hebron (South), Nablus (Center) and Jenine (North). The results revealed local variations in oil yield and solid waste product due to variations in the type of olive produced. The olives from the South were found to contain larger solid content than those from the North, .resulting in lower oil yield. The overall results indicated that the average oil yield was 23.7%, the solid waste product was 40.0% while the remaining balance was. the water. content (36.7%) in the olive fruit. A representative value at 1.7 m3/ton for wastewater generation was found to be high compared to similar values in other places of the world. This requires a criterious review of the technology and operation of olive mills in Palestine. The characteristics of OMW were found to violate the standards for OMW and this requires the attention of authorities.

Solid waste from Jordanian olive oil processing (OOSW) was used to prepare biochar samples by slow pyrolysis at terminal temperatures of 350, 450, 550 and 630 °C; henceforth known as BC-350, BC-450, BC-550 and BC-630, respectively. These samples were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction, ash content, moisture content and surface area. The ability of the biochar to remove Hg2+ ions from aqueous solutions was investigated in laboratory scale batch experiments. The kinetics, effect of pH and temperature were studied. The optimum pH value for Hg2+ adsorption was 5. Dubinin-Radushkevich (D-R) isotherm model was the best fit for the experimental results. Based on the D-R model, the maximum adsorption capacities at 25 °C were 84.93, 94.48, 96.11 and 104.59 mg.g−1, for BC-350, BC-450, BC-550 and BC-630, respectively. The pseudo-second-order kinetic model was a good fit for the experimental data. The calculated change in free energy ΔG and enthalpy ΔH indicated that the adsorption process was spontaneous and exothermic in nature. The positive value of ΔS showed increased randomness of the solid/solution interface during the adsorption. The results indicated that biochar derived from OOSW can be a good adsorbent for treatment of water contaminated with Hg2+.
