“…A VFA increase before Ripley's ratio would be anticipated in situations where there is high alkalinity, which also increases with load to dampen the response, for example, animal slurry and sewage sludge. Goodwin et al (2001) have reported operating data from a stressed upflow anaerobic sludge blanket (UASB) reactor when treating whisky distillery pot ale. A simultaneous increase in COD and reduction in HRT led to VFA concentrations of nearly 20 g/l and decreased biogas production, while pH levels stayed above 7 despite the almost complete reactor failure.…”

“…Values greater than 90% COD removal are commonly reported in the literature when there is high solubility and therefore biodegradability (Baloch et al, 2007;Borja et al, 1994;Connaughton et al, 2006;Cronin and Lo, 1998;Gonzalez et al, 1998;Leal et al, 1998;Zheng et al, 2012). Ahn et al (2001) reported a 76% soluble fraction for brewery waste, and Goodwin et al (2001) reported 78-84% solubility from whisky distillery pot ale. Average SCOD in this case study was 84·5% ± 10·6%.…”

“…The anaerobic digester in the study was the widely used and studied expanded granular sludge bed (EGSB) (Ahn et al, 2001;Alphenaar et al, 1993;Franklin, 2001;Gonzalez et al, 1998;Goodwin et al, 2001;Fuentes et al, 2011). The EGSB process relies on a rapidly settling (Lettinga et al, 1983), granulated biomass to uncouple solids retention from hydraulic flow.…”

Operational data from an anaerobic wastewater treatment plant (expanded granular sludge bed (EGSB) reactor) were analysed before and after a defect with the solids separator. The results presented suggest that a newly available method for the analysis of total volatile fatty acids (VFAs) was ideal as a rapid, onsite, operational indicator of reactor stability. These total VFAs were shown to provide an earlier warning of the separator problem than the other rapid routine methods of monitoring digesters such as alkalinity and suspended solids. Chemical oxygen demand (COD) removal, pH and gas yield were not as useful for monitoring because of their slow response. The results are from a high rate reactor; the loads were 18 kg COD/m 3 /d in the first year and 26 in the second with 4·4 d hydraulic retention time.The results for both years of operation demonstrate a 95% conversion of COD into gas with an additional contribution from solids digestion (specific gas yield of 0·4 l methane (CH 4 )/g COD rem ). This high performance was attributed to the solubility of the COD and the efficient EGSB mixing.

Handling and Treatment of Poultry Hatchery Waste: A Review

2011

A literature review was undertaken to identify methods being used to handle and treat hatchery waste. Hatchery waste can be separated into solid waste and liquid waste by centrifuging or by using screens. Potential methods for treating hatchery waste on site include use of a furnace to heat the waste to produce steam to run a turbine generator or to use an in line composter to stabilise the waste. There is also potential to use anaerobic digestion at hatcheries to produce methane and fertilisers. Hatcheries disposing wastewater into lagoons could establish a series of ponds where algae, zooplankton and fish utilise the nutrients using integrated aquaculture which cleans the water making it more suitable for irrigation. The ideal system to establish in a hatchery would be to incorporate separation and handling equipment to separate waste into its various components for further treatment. This would save disposal costs, produce biogas to reduce power costs at plants and produce a range of value added products. However the scale of operations at many hatcheries is too small and development of treatment systems may not be viable.

“…The upflow anaerobic sludge blanket (UASB) reactor, for instance, uses an upflow configuration with a three-phase (solids/liquid/gas) separator at the top. Due to the upflow nature of the process and the fact that anaerobic sludge granules and flocculent sludge tend to float, UASB reactors are particularly susceptible to the washout of solids [1][2][3][4].…”

A new high rate anaerobic technology, the static granular bed reactor (SGBR), for renewable energy production from medium strength waste streams

A new high rate anaerobic treatment system has been developed for maximizing the conversion efficiency of organic matter to energy in the form of methane for medium strength (1-10 g COD L -1 ) waste streams. The system, termed the static granular bed reactor (SGBR), utilizes a downflow hydraulic regime through a dense bed of active anaerobic granules that can accommodate higher suspended solids concentrations than its counterpart, the upflow anaerobic sludge blanket (UASB) reactor, which is susceptible to solids washout due to the high (up to 1 m h -1 ) upflow velocities. Theoretical considerations for the SGBR are presented with results from SGBR treatment of synthetic (non-fat dry milk and sucrose) and actual (pork slaughterhouse and landfill leachate) wastewaters documenting the high efficiency (consistently greater than 90% conversion of COD) and excellent effluent characteristics (typically less than 50 mg L -1 total suspended solids and BOD 5 ). Transient hydraulic and organic loads have relatively little effect on the SGBR as evidenced by consistent performance during an instantaneous shift in the hydraulic residence time from 36 to 5 h. In addition, results from variable reactor seeding from 25 to 100% of bed volume showed relatively little dependence of granule bed mass on effluent characteristics. This finding confirms independent results showing that a large fraction of the granule bed is substrate limited and available as reserve biomass. These results help explain the excellent treatment performance and resiliency of the SGBR regardless of hydraulic and organic loading. Fatty acid methyl ester (FAME) analysis of the granules showed distinct microbial communities entirely dependent on the nature of the feed source. Furthermore, FAME profiles from an anaerobic sequencing batch reactor (ASBR) treating pork slaughterhouse wastewater showed distinctly different profiles than an SGBR treating the same wastewater. Energy production from the SGBR was close to the theoretical 0.35 L (g COD removed)-1 for all waste streams evaluated.
