Anaerobic slurry co-digestion of poultry manure and straw: effect of organic loading and temperature
In order to obtain basic design criteria for anaerobic digestion of a mixture of poultry manure and wheat straw, the effects of different temperatures and organic loading rates on the biogas yield and methane contents were evaluated. Since poultry manure is a poor substrate, in term of the availability of the nutrients, external supplementation of carbon has to be regularly performed, in order ...
متن کاملEffect of organic loading rates (OLR) on production of methane from anaerobic digestion of vegetables waste
In this study, experiments were conducted to investigate the production of biogas from vegetable wastes by using anaerobic digestion process. The complete-mix, pilot-scale digester with working volume of 70 l was used. The experimental protocol was defined to examine the effect of the change in the organic loading rate on the efficiency of the production of biogas and to report on its steady-st...
متن کاملAnaerobic Digestion of Flushed Dairy Manure
In Florida, dairies use water extensively for barn flushing and waste collection, because it is sanitary and less labor-intensive. However, the practice of hydraulic flushing results in greatly increased volumes of dilute wastewater. In addition, many dairies have incorporated fan and sprinkler cooling systems for cow comfort in the warm Florida climate, which contributes even more water to the...
متن کاملEffects of Organic Loading Rate on the Performance of a Pressurized Anaerobic Filter in Two-Phase Anaerobic Digestion
The effect of organic loading rate (OLR) on a pressurized anaerobic filter was studied in a laboratory two-phase anaerobic digestion system. The anaerobic filter was operated successively at two working pressures (9 bar and 1.5 bar). The OLR(COD) for each pressure was increased from 5 to 17.5 kg·m·day. The best performance of the reactor at 9 bar was observed at OLR(COD) of 12.5 kg·m·day and hy...
متن کاملAnaerobic digestion of chicken manure as a single substrate by control of ammonia concentration
Anaerobic digestion of high solids chicken manure as a single substrate was conducted at laboratory scale with a reaction volume of 10 l. The organic loading rate was increased gradually from 2.2 to 3.9 gVS l -1 d -1 . To reduce the amount of inhibiting ammonia in the process technical stripping of ammonia was applied, yielding ammonia-phosphate or ammonia-sulfate as valuable side-products. A h...
