Simultaneous Synthesis of a Biogas Process and Heat Exchanger Network for a Large-scale Meat Company
The aim of this contribution is to present an industrial application of mathematical programming for the simultaneous synthesis of a biogas plant and its heat exchanger network (HEN), within an existing meat company. The heat-integrated model recently developed by Drobež et al. (2010) has been extended with Yee & Grossmann simultaneous optimization MINLP model (1990) for the synthesis of heat e...
We assessed the effect of closing live poultry markets in China on influenza A(H7N9) virus detection and viability. Intensive sampling was carried out before, during, and after a 2-week citywide market closure; the markets were cleaned and disinfected at the beginning of the closure period. Swab samples were collected at different sites within the markets and tested for H7N9 by real-time revers...
Mass culling is a strategy used inthe management of infectious disease outbreaks. The risk of disease spread due to animal transportation often precludes the use of slaughterhouses for this purpose, though they have been used on occasion. Consequently, culling takes place in the less-than-standardised environment on the farm. Regardless of where the cull occurs, the methods chosen to handle and...
Campylobacteriosis is one of the most important bacterial food-borne illnesses in humans. One significant source of infection is the handling and consumption of poultry meat, although other sources also contribute considerably. Controlling Campylobacter in broilers reduces the human burden of illness. Broilers can easily become colonised with Campylobacter and preventive measures in primary pro...
Water samples (24 untreated water, 12 treated water and 24 served water) used in different stages of the slaughter process were examined to identify a possible source of pathogenic mycobacteria. The isolates were identified based on microscopy, morphological and biochemical features, mycolic acid analysis and molecular method--PCR-restriction-enzyme analysis. Eighteen mycobacterial strains were...
Salmonella is the most commonly identified foodborne pathogen in produce, meat and poultry. Cattle are known reservoirs of Salmonella and the pathogen excreted in feces ends up in manure flush lagoons. Salmonella enterica survival was monitored in wastewater from on-site holding lagoons equipped or not with circulating aerators at two dairies. All strains had poor survival rates and none prolif...
The conversion of municipal sludge and poultry manure to activated carbon results in a significant ash fraction that contains several different anions and cations. The objectives of this study were to determine whether the select ions are released or leached from virgin carbon into the sorption medium at different pH values. Activated carbon was placed in solutions of pH 1, 5, or 7, and the lea...
The number of slaughterhouse facilities and retail meat shops has been on the rise, leading to an increase in amount wastewater they produce. Wastewater is hazardous environment as it causes deoxygenation water bodies, pollutes groundwater, spreads several diseases if released untreated. study was conducted slaughter slabs Kirtipur Municipality evaluate physicochemical characteristics microbial...
