:The carbonised solid residue of olive mill products, called J-carbon (0É6È0É7 mm), was compared with Sigma activated carbon (powder) and Chemviron activated carbon (0É6È0É7 mm) in treatment of the effluent of FlexsysÏ wastewater. The removal of TOC as non-speciÐc organics, and six speciÐc NH 3 , leading organic pollutants from FlexsysÏ wastewater effluent were examined.

This work is aimed to evaluate the applicability of solid portion of olive mill wastewater (OMW) for its utility as a renewable biofuel. A solar still unit was used to separate the solid residual from the liquid part of OMW. Three triplicate samples of solid residue were collected and tested for their calorific value, proximate analysis, and elemental analysis. The average calorific values obtained based on oxygen bomb calorimeter were 24 ± 0.65 kJ/g which agreed well with that obtained from elemental analysis (23 ± 1.3 kJ/g). This value is higher than that of refuse-derived fuel and lower than that of oil or natural gas but close to that of coal. Results of proximate analysis indicate a high combustible portion (83%) of OMW-Biofuel. The total amount of energy that can be produced from OMW-Biofuel in Jordan, expressed in terms of oil equivalent, accounts for \1.0% of the total imported oil by Jordan in 2014 and, if utilized, would result in annual savings of about US$ 17 million. These results suggest that the OMW-Biofuel can be applicable as a potential fuel.

The levels of cadmium, nickel, manganese, lead, zinc, iron, tin, copper and arsenic in fresh sheep's milk, white brined cheese preserved in glass jars and in tin containers and their corresponding brines, salt and tin plates were determined by atomic absorption spectrophotometry. The results have been compared with those reported in recent years. Although metal levels were comparable with other investigators' data, our data shows that white brined cheese picked-up metals from tin containers and from the naturally contaminated salt, on the contrary brined cheese in preserved glass jars showed lower levels of metals. We recommend a purified salt for brine preparation and glass jars for white cheese preservation in order to minimize cheese contamination with metals from tin cans and salt.

The present study was conducted on a pilot scale level using a solar still unit to separate olive mill wastewater (OMW) into condensate and solid residue. The prevailing conditions inside the solar still, rates of distillation and a number of quality parameters for condensate [pH, electrical conductivity (EC), turbidity, chemical oxygen demand (COD), total organic carbon (TOC), total nitrogen (TN) and totalphenols] were evaluated to assess the system performance. The solid residue was evaluated as well for its utility as a potential biofuel. The condensate is acidic (pH 3.8), colourless, transparent and free of suspended solids. The turbidity and EC were reduced in the condensate by 100 and 99%, respectively, while the loads of COD, TOC, TN and T-phenols were reduced by 90, 98, 99.9 and 99.96%, respectively. Almost 0.04% of initial total phenols found in OMW were recovered in the condensate. High calorific value (23.5 kJ/g) and combustible portion (84%) of solid residue suggests its applicability as a potential biofuel 134
