“…If Sarioglu et al (2010) used anaerobic sewage sludge taken from an up-flow anaerobic sludge blanket reactor treating the wastewaters of Pakmaya Yeast Factory, cumulative methane gas production decreased to 55 and 43 %, respectively for 500 and 1000 mg Zn • l -1 . Lin and Chen (1999) tested sludges that were obtained from an up-flow anaerobic sludge blanket reactor treating winery wastewater, the concentration at which zinc caused 50 % inhibition of methane production was 690 and 270 mg Zn…”

The most frequently found metals in municipal sewage sludge are copper and zinc. The aim of this study was to the evaluate effect of these metals on anaerobic microorganisms during sewage sludge stabilization. Anaerobic fermentation tests were carried out in 24 batch fermenters with hydraulic retention time 21 days at mesophilic temperature conditions 38 °C ± 0.2 °C. Five different concentrations of metal ionts (100-1000 mg•l -1 ) were tested. Cumulative biogas and methane production were used as the comparative parameters of inhibition. Hypothesis, which predicted presence of inhibitory effect of zinc and copper on anaerobic microorganisms, mainly on methanogenic Archaea, was confirmed. The lowest concentration of zinc and copper which cause significant inhibition of biogas production was 400 mg Zn , which cause reduction of 10.3 ± 2.0 % and 82.8 ± 1.1 %, respectively. The lowest concentration of zinc and copper which lead to significant inhibition of methane production is 400 mg Zn 2+ •l -1 and 600 mg Cu 2+•l -1 , which caused to reduction of 16.1 ± 3.2 % and 17.4 ± 2.2 %, respectively. The reduction in methane production is higher than in biogas production.

“…The study of the effect of Ni, Zn and Cu on pure cultures of Methanospirillum hungatei JF1, Methanosarcina barkeri MS, Methanothermobacter marburgensis and Methanobacterium formicicum (Jarrell et al 1987) showed that Zn and Cu were toxic at concentrations from 0.015 to 0.15 and 0.017-0.17 mM, respectively, while Ni was described as being the least toxic of the three metals; particularly, M. formicicum was the most resistant of the methanogens towards Ni; for example, 0.26 M of Ni were needed to induce 50 % inhibition to this microorganism while the other two microorganism where sensitive to concentrations between 4.25 and 20 mM. Using an anaerobic sludge from a UASB reactor treating wastewaters from a yeast factory, (2015) 14:537-553 547 Sarioglu et al (2010) Due to significant variations in the experimental conditions evaluated and differences in results, it is hard to find a pattern and establish an average concentration at which the metals become toxic. In general, Cu is one of the most toxic metals while Pb is one of the most tolerated.…”

“…the lanthanides (atomic number 57-71), are generally not considered as heavy metals. The Irreversible failure for systems using propionate; sulphate reduction was shutdown before methanogenesis; in similar conditions, propionateusing systems failed before acetate-using systems Parkin et al (1990) Granular sludge from a full-scale UASB reactor treating papermill wastewater development of certain industries, such as metal plating, mining, paper, pesticides and storage batteries, glass and ceramic, contributed for the increase of heavy metals concentration in wastewaters (Sarioglu et al 2010). In Table 2 the concentrations of some heavy metals found in wastewaters are mentioned.…”

Anaerobic digestion (AD) is a well-established technology used for the treatment of wastes and wastewaters with high organic content. During AD organic matter is converted stepwise to methanecontaining biogas-a renewable energy carrier. Methane production occurs in the last AD step and relies on methanogens, which are rather sensitive to some contaminants commonly found in wastewaters (e.g. heavy metals), or easily outcompeted by other groups of microorganisms (e.g. sulphate reducing bacteria, SRB). This review gives an overview of previous research and pilot-scale studies that shed some light on the effects of sulphate and heavy metals on methanogenesis. Despite the numerous studies on this subject, comparison is not always possible due to differences in the experimental conditions used and parameters explained. An overview of the possible benefits of methanogens and SRB co-habitation is also covered. Small amounts of sulphide produced by SRB can precipitate with metals, neutralising the negative effects of sulphide accumulation and free heavy metals on methanogenesis. Knowledge on how to untangle and balance sulphate reduction and methanogenesis is crucial to take advantage of the potential for the utilisation of biogenic sulphide as a metal detoxification agent with minimal loss in methane production in anaerobic digesters.

“…Because of the importance of eliminating toxic materials, many studies have been done on the characteristics, kinetic, equilibrium, and elimination of various heavy metals and other toxic materials [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Cadmium, as an important member of toxic heavy metals, has harmful effects on the health of animals and humans [20].…”

A B S T R A C TIn the present work, blowy sand, as a cheap and available adsorbent, was employed to remove the Cd 2+ from water and obtain the best kinetic and isotherm models for this elimination process. In addition, the effects of total hardness and pH on this process were examined to obtain the best conditions for elimination of Cd 2+ . The calibration of kinetic and isotherm models shows that the model presented by Ho and co-workers is the best kinetic model and Redlich-Peterson model is the best isotherm model for presentation of our results. The pH equal to 5 is the best acidic condition to remove Cd 2+ in all conditions. Moreover, by the increase of total hardness from 0 to 320 (in milligrams of calcium carbonate), the efficiency and capacity of adsorption will decrease, respectively, from 80.4% to 18.7% and from 0.331 to 0.067 mg/g. The reusability of adsorbent without decreasing its efficiency is three times.
