The pH was found in the alkaline range (7.8-9.14). The sediment and water samples were then prepared through direct digestion and finally analyzed by atomic absorption spectrophotometer (AAS). The results showed that the heavy metal concentrations in SSC were considerably higher than those measured in water samples. So that metal concentrations in the sediments ranged from 1.26 to 38.83 mg/g for Fe, 10.99 to 541.18 µg/g for Zn, 4.05 to 39.94 µg/g for Cr and 4.31 to 91.46 µg/g for Ni. While metal concentrations in water samples ranged from 0.09 to 2.695 mg/g for Fe and found non-detectable for Zn, Cr and Ni.

Leachate readily reaches the nearby water resources such as streams, rivers, lakes, and sea. Therefore, understanding the quality and quantity of open dump leachate is vital to the proper treatment of leachate.

Various carbon sources including formate, acetate, malate, glucose, fructose, and sucrose were applied to support microbial growth in the presence of CO-rich syngas. The microorganisms utilized carbon monoxide and produced molecular hydrogen concurrently. The process was analyzed based on both conventional exergy and eco-exergy concepts for determining the exergetic parameters i.e., exergy destruction and exergy efficiency. Unlike the exergy efficiency, the exergy destruction based on the ecoexergy concept was remarkably lower than what obtained via the conventional exergy theory. Minimum normalized exergy destruction values of 189.67 and 181.40 kJ/kJ H 2 were achieved for acetate as substrate using the exergy and eco-exergy approaches, respectively. In better words, acetate was identified as the most appropriate carbon source for biohydrogen production from the exergy point of view. Finally, the findings of this study confirmed that exergy analysis could be employed as an adaptable framework to determine and compare the renewability of biological hydrogen production using different routes in order to decide on the most suitable approach and conditions.

The porosity characteristics of these ACs were determined by N 2 adsorption isotherms. Through varying the H 3 PO 4 /biomass ratio from 1.5 to 2.5, the prepared ACs displayed BET surface areas in the range of 1875-2117 m 2 /g with micropores content of 69-97%. For the ZnCl 2 activated series, BET surface areas varying from 1274.8 to 2107.9 m 2 /g with micropores content of 93-100% were obtained from impregnation ratios of 0.75-2.0. The AC obtained by KOH had the largest BET surface area of 2594 m 2 /g and the high micropore content of 98%. In addition, the FTIR and SEM analyses conducted for characterizing the ACs and the CO 2 adsorption onto all series of the eucalyptus wood based ACs at pressures ranging from 0 to 16 bar using a volumetric method were investigated. Also the effect of temperature (15-75 8C) on the amount of CO 2 adsorbed by the ACs that was prepared with H 3 PO 4 , KOH and ZnCl 2 was studied. The CO 2 adsorption capacity on the AC prepared with KOH was up to 4.10 mmol/g at 1 bar and 303 K, having an increase of about 63% in comparison with the commercial AC.

The effect of each four factors, viz. the dosages of alum and PACl, pH and chemical oxygen demand (COD), on the treatment efficiency was investigated. The influence of these four parameters was described using response surface methodology under central composite design. The efficiency of reducing turbidity, COD and the sludge volume index (SVI) were considered the responses. The optimum conditions for high treatment efficiency of paper-recycling wastewater under experimental conditions were reached with numerical optimization of coagulant doses and pH, with 1,550 mg/l alum and 1,314 mg/l PACl and 9.5, respectively, where the values for reduction of 80.02 % in COD, 83.23 % in turbidity, and 140 ml/g in SVI were obtained.

Dry deposition fluxes of water soluble ions were collected weekly for 14 months (Oct. 2010 to Dec. 2011). The results showed that the weekly dry deposition mass fluxes ranged from 16.48 to 922.68 mg m −2 day −1 , with annual average deposition of 159.37, 124.46 and 237.09 in mg m −2 day −1 in Abali, Firouzkouh and Varamin, respectively. In Abali, Na + , SO 4 2− and NO 3 − the dominant ionic species were Na + , SO 4 2− and NO 3 − , SO 4 2− , Ca 2+ and NO 3 − and SO 4 2− , Na + and Ca 2+ , accounting for 28%, 23% and 17%, 36%, 25% and 18% and 30%, 20% and 19% of the total mass of ions, in Abali, Firouzkouh and Varamin, respectively. Dry deposition flux of major ions was higher during the dust storm and other weather phenomena. Air mass back trajectories calculated for all three sampling sites on October 2011 (when there was pollution), revealed four sectors of air mass origin: NW to N of Siberia/Russia and Caspian Sea, local, Middle East and W to SW of Oman Sea. Seasonal variation of total ion flux was significant, with the highest depositions observed in winter 2011, autumn 2010 and autumn 2011 and the lowest depositions in spring 2011, spring 2011 and autumn 2010 in Abali, Firouzkouh and Varamin, respectively. These major ions were mainly in the form of Ca(NO 3 ) 2 , CaSO 4 , CaCl 2 , and NaCl. Firouzkouh had the lowest NO 3 − /SO 4 2− flux value among the two other sampling sites, indicating that the stationary source of the air pollution was the more dominant one. Stationary emissions were still the dominant source in all three sampling sites demonstrated by the NO 3 − /SO 4 2− ratio being lower than one. NO 3 − , SO 4 2− and NH 4 + were primarily affected by anthropogenic emissions, while SO 4 2− might have been partially

Results of experiments showed that COD/N/P ratio 1000/250/2 and Q 7 L/h in HRT 6 h, F/M 0.054 kg COD/kg MLVSS.h and OLR 0.15 kg/m3 .h were desirable for removal of nutrients from wastewater in aerobic/anaerobic bioreactor. In these conditions SVI 53.12 mL/g, COD removal efficiency 86% and PO4 3- removal efficiency 97.5% were showed. According all results of responses for best nutrient removal, UAASB bioreactor is desirable for removal efficiency of C and P.
