“…Nevertheless, thermophilic condition is used a lot of investigation in cattle manure alone study because of its more efficient to produce biogas at cattle manure digestion (Abubakar and Ismail 2012;Ahring et al 2001;Boe and Angelidaki 2009;ElMashad et al 2004;Mohaibes and Heinonen-Tanski 2012;Omar et al 2008;Sung and Santha 2003). In cattle manure alone digestion studies, HRTs were conducted between 10 and 20 days, while biogas production usually ranged from 0.15 to 0.30 L CH 4 g -1 VS day -1 with COD-VS removal ranged from about 30-55 % (Abbasi et al 2011;Ahring et al 2001;Demirer and Chen 2005;El-Mashad et al 2004;Ghaly 1989;Gungor-Demirci and Demirer 2004;Omar et al 2008;Rico et al 2011;Sung and Santha 2003).…”

This literature review surveys the previous and current researches on the co-digestion of anaerobic processes and examines the synergies effect of co-digestion with cattle manure. Furthermore, this review also pays attention to different operational conditions like operating temperature, organic loading rate (OLR), hydraulic retention time (HRT), chemical oxygen demand (COD) and volatile solid (VS) removal efficiency and biogas or methane production. This review shows that anaerobic mono-digestion of cattle manure usually causing poor performance and stability. Anaerobic studies were generally performed under mesophilic conditions maintained between 35 and 37°C. Organic waste loading rate generally ranges from 1 to 6 g VS-COD L -1 day -1 stable condition in anaerobic digester. Generally, studies show that HRT for co-digestion of fruit-vegetables waste and industrial organic waste appears to exceed 20 days. However, the anaerobic co-digestion process is generally operated at HRT of between 10 and 20 days. VS and COD removal efficiency usually reaches up to 90 % due to codigestion with different type organic waste. Methane-biogas production is generally obtained between 0.1 and 0.65 L CH 4 -biogas g -1 VS.

“…Generally, the shorter the HRT the lower the TVS reduction. De la Rubia et al (2002) reported an increase in the TVS reduction (from 53-73%) as the HRT increased from 27-75 d. Ribas and Barana (2003) reported an increase in the TVS from 1.6-4.3% in a wastewater treatment system as the HRT was decreased from 16.6-9.7 d. Umana et al (2008) reported an increase in the TVS reduction (from 26.3-78.8%) during the treatment of dairy manure as the HRT was increased from 1-5.5 d. Rico et al (2011b) noted that the concentration of TVS increased from 23.7-27.8 g L −1 during anaerobic treatment of dairy manure as the HRT decreased from 20-10 d. The reduction in the TVS obtained in this study (25.2-39.7%) were within the range reported in the literature. The diurnal cycling temperature also affected the TVS reductions, the higher the temperature the higher the TVS reduction.…”

“…Huang et al (2011) reported that the higher biogas yields were achieved at lower HRTs (8-12 h) during wastewater treatment. Rico et al (2011b) noted that as the HRT decreased from 20-12.5 d, the biogas production increased from 0.66-1.21 m 3 during the anaerobic digestion of dairy manure. In this study, higher biogas production was observed with higher temperatures (within the temperature range studied).…”

Problem statement: Concentrated livestock production is a major contributor to environmental problems through the production of large quantity of husks on relatively small land area. Anaerobic digestion represents a valuable means of cover by these husks into methane while reducing manure pollution problems. Methodology: An experimental apparatus, including data acquisition and control system, was developed and used to investigate the effects of two diurnally cyclic temperature ranges (20-40 and 15-25°C) and four levels of hydraulic retention times (25, 20, 15 and 10 d) on the performance of anaerobic reactors operated on screened dairy manure. Results: The reactor temperature exhibited a lag relative to the chamber temperature. For the 20-40°C temperature cycles, the average lag at the maximum chamber temperature was 3.75 h while the lag at the minimum chamber temperature was 4.37 h. For the 15-25°C temperature cycle, the average lag at maximum chamber temperatures was 3.61 while the lag of the minimum chamber temperature was 4.34 h. The effluent solids content, total Kjeldahl nitrogen and ammonium nitrogen concentrations were not adversely affected by the reactor diurnally cyclic temperature. The observed values of these parameters compared fairly well with the values obtained by other researchers. The effluent total solids, volatile suspended solids, TKN, NH 4 -N and methane content of the biogas diurnally cyclic patterns were out of phase with the diurnally cyclic pattern of the reactor temperature by about 12 h under most of the investigated operating conditions. The pH and the carbon dioxide content of the biogas all exhibited a diurnally cyclic pattern which was in phase with the reactor diurnally cyclic temperature. The reductions in total solids, total suspended solids, fixed suspended solids, total Kjeldahl nitrogen, ammonium nitrogen and methane yield were all significantly affected by the diurnal temperature range and hydraulic retention time. Conclusion: The measured reactor pH followed a diurnally cyclic pattern which was in phase with the reactor temperature. At the operating temperature cycle of 20-40°C, the reactor pH ranged from 6.80-7.54 while VFA concentration ranged from 44.7-154.8 mg L .

“…Anaerobic treatment provides a method of reducing pollution from agricultural and industrial operations while at the same time offsetting the operations' usage of fossil fuels. As one of the most efficient and least expensive waste treatment technologies for developing country such as DR CONGO, anaerobic digestion offers numerous significant advantages, such as low sludge production, fertilizer production , energy recovery and deforestation reduction [1][2][3][4][5].…”

Inhibitory compounds are often found to be the leading cause of anaerobic reactor upset and failure since they are present in substantial concentration in wastewaters and organic solid wastes. Among these inhibitory compounds, organic compounds are mentioned and more especially aromatic compounds. The purpose of this work was to evaluate the effect of bisubstituted aromatics functional groups on the methanogenic inhibition. The toxicity to acetoclastic methanogenic bacteria has performed in serum flasks, utilizing digested pig manure as inoculums, by measuring cumulative methane production. The results obtained indicate that some general relationships exist between the bisubstituted aromatic structures and their inhibitory effects on methanogenic bacteria. This demonstrates sufficiently that the grafting of hydrophobic or hydrophilic substituent on the benzene or monofunctional aromatic compound, make the obtained compound more or less toxic as the case and that in the same order of toxicity. A significant correlation was obtained indicating that the partitioning of bisubstituted aromatics into lipophilic membranes in bacteria may have a role in the inhibition of methane biosynthesis.
