This study investigates the digestion of cow dung (CD) for biogas production at laboratory scales. The study was carried out through anaerobic fermentation using cow dung as substrate. The digester was operated at ambient temperatures of 39.5 °C for a period of 10 days. The effect of iron powder in controlling the production of hydrogen sulfide (H2S) has been tested. The optimum concentration of iron powder was 4g/L with the highest biogas production. A Q – swatch Nd:YAG laser has been used to mix and homogenize the components of one of the six digesters and accelerate digestion. At the end of digestion, all digestions effluent was subjected to 5 laser pulses with 250mJ/pules to dispose waste biomass.

Anaerobic digestion is one of solution to environmental problems and energy sources for current energy needs. In anaerobic digestion, organic material is degraded by bacteria, which is carried out without oxygen, and converts it to a mixture of methane and carbon dioxide. POME can be degraded anaerobically in anaerobic digester to produce biogas. This study aims to increase the conversion of biogas produced using a 2 liter Continuous Stirred Tank Reactor (CSTR) type digester in the methanogenesis process by recycling the effluent produced through the ultrafiltration membrane in a transition condition (45oC). The process is carried out by varying the recycle ratio, which is 0%, 15% and 25% on HRT 6 days with a condition of pH 7 ± 0.2. The highest average biogas production was achieved at the 25% recycle ratio of 33.15 x 10-5 L / mg VS. day, with the composition of methane, carbon dioxide and hydrogen sulfide each of 79%; 19%; and 0.006%, with degradation of VS and COD of 39.58% and 66.33% respectively. For the composition of the highest CH4 content obtained at a variation of the 15% recycle ratio which is equal to 85% while for the composition of carbon dioxide, and hydrogen sulfide each is 14%; and 0.0076%.

Waste biomass from the industrial production of the amino acid L-cystine contains above-average concentrations of organic pollutants and significant concentrations of nitrogen and sulfur. The specific biogas production (SBP) of waste biomass was monitored in parallel suspended-growth laboratory anaerobic bioreactors. After severe inhibition was observed, three different procedures were applied to inhibited reactor sludge to counter-attack the inhibitory effects of sulfides, respectively hydrogen sulfide: micro-aeration, dilution with water and precipitation by ferrous iron cations. The performance of bioreactors was weekly monitored. Organic loading rates (as chemical oxygen demand, COD) ranged from 1.07 to 1.97 g L−1 d−1. At the end of the experimentation, SBP averaged 217, 300 and 320 l kg−1 COD with a methane content of 21%, 52% and 54%; specific sludge production averaged 133, 111 and 400 g total solids kg−1 COD, and inhibition was 49%, 27% and 25%; for the applied procedures of micro-aeration, dilution and precipitation respectively.

Anaerobic digestion is the decomposition of organic matter by microbes into methane, carbon dioxide, and hydrogen sulfide in the absence of oxygen. This study aimed to obtain the stability of the one stage anaerobic digester in biogas production that was seen through pH and alkalinity parameters. The process was carried out by varying the temperature, which is 35 °C, 45 °C, and 55 °C with pH maintained 7 (± 0.2). Analysis of pH and alkalinity was carried out to assess the stability of reactor using samples taken from the reactor overflow. The pH profile produced was relatively stable with a pH range between 6.8 - 7.3. The resulting alkalinity is relatively stable with aalkalinity range between 3.500 – 4.500 mg/L. The volume of biogas produced at 35 °C, 45 °C, and 55 °C respectively are 2065 mL, 3830 mL, and 4570 mL with the highest concentrations of methane (CH4), Carbon dioxide (CO2) and trace Hydrogen Sulfide (H2S) at a temperature of 55 oC obtained the value of the composition of methane, carbon dioxide, and hydrogen sulfide each at 89,000 %, 11,000 %, and 0,011 %.
