Anaerobic biodegradation and characterization of wastewater produced at household level in rural areas in Jordan were considered in this study in order to investigate the possibility of applying house onsite low cost treatment systems. Results showed that the total chemical oxygen demand (CODtot) was 1.8 times higher during summer than during winter. The average CODtot during summer and winter ...

Sec. 457. On or before October 15, 2008, and on a quarterly basis thereafter, the department shall report to the senate and house agriculture committees, the senate and house appropriations subcommittees on agriculture, and the senate and house fiscal agencies on the department’s progress toward meeting USDA requirements as outlined in the March 2007 bovine TB program review. The report shall i...

background: hospitals generate relatively large quantities of wastewater that may contain various potentially hazardous ma­terials; therefore the proper management of hospital wastewater is essential. methods:   in this cross-sectional study, the quality and quantity of wastewater in the hospitals of tehran university of medi­cal sciences (tums), tehran, iran, were studied and the suitable meth...

The possible sources of Campylobacter spp. in poultry meat before slaughter were studied by examining samples of feathers, cloaca swabs, litter swabs, transport coops, rinse water from coop washing equipment, and chicken breast supports in the slaughter line just before stunning. The samples were collected from 8 broiler houses and from 8 different producers, from a poultry integration system i...

Large creamy color livers of some chickens from a commercial broiler flock, reared in Tehran province, were noticed in a slaughter house. Myeloid leukosis (myelocytoma) characterized by presence of typical gross and microscopic lesions was diagnosed. Further studies for assessment of prevalence of this disease in broiler breeders and broilers flocks was suggested.

About 700,000 on-site wastewater treatment systems (OWTS) have been installed in Sweden, serving both year-round and summer houses (Olshammar et al., 2015). Their treatment efficiency is often questioned, because they may contribute considerably to eutrophication of natural surface waters. It is estimated that the phosphorus (P) discharge of all the OWTSs accounts for 15% of the total anthropog...

the aim of this study was to determine the principal reasons for condemnation of broiler poultry carcasses and its economic losses in namin slaughter-house of iran from  february 2008 to  march 2009 . in this period, 2741794 poultry were slaughtered which were7662237 kg live weight and 5560963 kg eviscerated meat .from these , 20479 carcasses responsible for 0.74% of total slaughter with overal...

The trend towards reuse of effluent for land application of domestic and industrial wastewater is driven by the need to maximise limited water resources and benefit from the plant nutrients available in the effluent. Of significant impact upon the value of the wastewater for reuse is its chemical properties as well as biochemical oxygen demand and suspended solids. While the sewage treatment pl...
