“…A possible alternative could be a combination of a leach bed with a high-rate anaerobic digester (generally upflow anaerobic sludge blanket) and combined side-stream ammonia removal. This has been effectively applied for diluted poultry manure (Yetilmezsoy and Sakar, 2008;Rao et al, 2008).…”

Biochemical Methane Potential of Beef Feedlot Manure: Impact of Manure Age and Storage

Methane capture and use from intensive livestock industries is relatively new, and there is limited chemical and kinetic degradation information available for beef feedlot manure in Australia or internationally. This paper evaluates the biochemical methane (CH) potential, apparent first-order hydrolysis rate coefficient, and losses in organic content of manure as it ages on feedlot pads and in stockpiles. Chemical characterization of fresh, pad, and stockpiled manure is assessed. Biochemical CH potential on volatile solids (VS) almost always decreased significantly from fresh to pad and from pad to stockpile, ranging (in mL CH g VS) from 230 to 360 in fresh manure, from 70 to 280 in pads, and from 60 to 200 in stockpiles. Kinetics of degradation also varied with manure age (fresh: 0.12 ± 0.01 d; pad: 0.06 ± 0.02 d; and stockpiled: 0.05 ± 0.04 d). At least 50%, and up to 80%, of the original biochemical CH potential of the manure (i.e., degradable material) was lost on drying in pads, and the loss after stockpiling was much greater (>85%). The loss of N was 15 to 60% as manure dried on pads and was much greater after stockpiling (40-90%). Phosphorus loss, though lower than nitrogenous losses, was still significant (25-65% on pads and 35-85% in stockpiles). Although digestion of stockpiled manure is still feasible to generate energy, collection of fresh manure is important to maximize outcomes, with a possible order of magnitude increase in CH production achievable.

“…Jaffer et al [17] and Demirer et al [18] proposed the addition of magnesium salts to the digesters to obtain struvite (magnesium-ammonium phosphate) by precipitation. Gangagni-Rao et al [19] introduced a stripper with a UASB reactor treating poultry litter leachate to diminish the inhibitory effect of ammonia. A COD removal of 96% and a methane yield of 0.26 L/g COD removed were achieved at an organic loading rate of 18.5 g COD/L day and a hydraulic retention time of 12 h, while in the control the maximum organic loading accepted without inhibition was 13.6 g/L d at a hydraulic retention time of 16 h. Borja et al [20] compared the anaerobic digestion of cow manure using natural zeolite as support with a control in batch digesters.…”

This work presents the effect of ammonia nitrogen concentration and zeolite addition on the specific methanogenic activity (SMA) of different anaerobic sludges with various physical structures (granular and flocculent), operating in batch conditions. Piggery, malting production and urban sludges derived from full-scale anaerobic reactors were tested in the experiment as the source of inoculum in batch digesters. It was found that piggery sludge was the most affected by the increase of ammonia nitrogen concentration while malting producing and municipal sludges were less affected. In general, the addition of zeolite at doses in the range of 0.01-0.1 g/g VSS reduced the inhibitory effect of N-NH(4)(+) for piggery sludge (P.S.). For this sludge, the propionic:acetic ratio increased when the concentration of N-NH(4)(+) increased, indicating that methanogenesis was affected. Finally, a study of the microbial population involved in this study for P.S. by using 16S rRNA based molecular techniques revealed a presence of microorganisms following the order: Methanococcaceae > Methanosarcina > Methanosaeta.

“…However, the COD concentration of the effluent was about 4000 mg/L, and the ammonia concentration was close to 1000 mg/L, which are much higher than the outlet standard [29]. Air stripping or biological nitrification/denitrification were the effective methods for removing ammonia in wastewater [30,31]. Meanwhile, several researchers have also proven that membrane processes obtain wastewater of recyclable quality successfully [32].…”

This paper describes the feasibility of fresh leachate treatment by an upflow blanket filter (UBF). Through dilution and partial effluent recycling, the organic loading rates increased from 0.51 to 14.56 kg COD/(m 3 $d), meanwhile the corresponding hydraulic retention time decreased from 9.0 to 3.6 d. The reactor was able to achieve steady-state within 80 d. Based on the distribution of COD fluxes in the process, it was concluded that anabolism was the main pathway of COD removal in the initial phase (1-33 d), accounting for 57%-85% of total COD removed. As the anaerobic consortium of bacteria reached steady-state (after 70-86 d), the majority of COD removed was transformed into methane, because the specific methane yield was close to the theoretical value (0.36 L CH 4 /(g COD deg )).
