Although electrochemical methods are one of the most efficient approaches for treating wastewater, type wastewater to be treated, electrode material employed, and polarity direction all significantly affect how well these systems work. The prospective application proposed materials purification slaughterhouse effluent has not been sufficiently explored in earlier studies, despite fact that (cop...

OBJECTIVES To investigate the presence and distribution of integron-carrying bacteria from a slaughterhouse wastewater treatment plant (WWTP). METHODS Enterobacteriaceae and aeromonads were isolated at different stages of the wastewater treatment process and screened for the presence of integrase genes by dot-blot hybridization. Integrase-positive strains were characterized in terms of phylog...

Long carbonation time has been a common feature in the integrated process composed by immediate one-step lime precipitation and atmospheric carbonation. This work aims to understand how can be influenced reaction pH, as well reactor area/volume ratio affects ammonia removal, using slaughterhouse wastewater due its variable characteristics. In process, results showed that pH type of however, rem...

Nutrients (nitrogen and phosphorus) are among the water quality parameters that cannot be easily removed from wastewater. Unfortunately, excessive accumulation of nutrients in can lead to numerous health issues for humans environment general (including aquatic life). This study looked into potential use polymeric nanofiltration membranes remove total phosphorus, ammonia, nitrate, nitrite poultr...

Presented in this paper is a graphical technique for freshwater and wastewater minimisation in completely batch operations. Water minimisation is achieved through the exploitation of inter- and intra-process water reuse and recycle opportunities. In the context of this paper, a completely batch operation is one in which water reuse or recycle can only be effected either at the start or the end ...

BACKGROUND Brucellosis is a major public health problem in developing countries and has remained endemic in Iran. The aim of this study was to investigate the Seroprevalence of Brucellosis among high risk individuals in Guilan, Iran. METHODS In a cross-sectional study, 478 blood samples from people living in rural areas (n = 292) and 186 slaughterhouse workers were screened by slide agglutina...

BACKGROUND There is interest in applying bacteriophages to control Salmonella in pig production and pork processing. The following reports on the prevalence of Salmonella infecting bacteriophages within Ontario pig farms and associated with the holding area of a pork slaughterhouse. RESULTS Salmonella infecting bacteriophages were present in 30 and 28 of the effluent manure samples collected ...

The aim of this survey was to obtain data on microbiological contamination of pig carcasses and environments in three large-scale Italian slaughterhouses (identified as A-B-C) located in Northern Italy. Each slaughterhouse was visited six times. Five carcasses and three different sites of the slaughterhouse (before and during slaughter) were sampled on each sampling day. A single pooled caecal ...
