New and improved methods are needed to disinfect pathogens in treated wastewater, especially highly resistant ones like Cryptosporidium parvum oocysts. In addition, new and improved methods are needed to detect pathogens and indicators for them in wastewater in order to monitor the efficacy of disinfection and other waste water treatment processes. Spores of the anaerobic bacterium Clostridium ...
The crude recycling of electronic and electric waste (e-waste) is now creating a new set of environmental problems especially in developing countries such as China. The present study aimed to characterize the dioxin-like compounds in Taizhou area, one of the largest e-waste recycling centers in China, using both chemical analysis and in vitro bioassay. Agricultural soil samples were screened fo...
OBJECTIVE The first aim of this study was to evaluate the antimicrobial resistance of Enterobacteriaceae in different water environments of Guadeloupe and especially those impacted by waste water treatment plants (WWTP) effluents. The second objective was to characterize the genetic basis for antibiotic resistance of extended-spectrum beta-lactamase (ESBL) and AmpC beta-lactamase producing Ente...
Landfill location is one of the most important aspects of municipal solid waste management. Selecting a suitable solid waste landfill site can prevent adverse ecological and socioeconomic effects. Therefore, the aim of this paper was to determine the solid waste landfill site selection problem in Bushehr city, according to some criteria including the considered land use, distance from surface a...
Vermicomposts have been shown to promote the germination, growth, and yields of plants. This paper aims to demonstrate the effects of vermicomposts produced from three types of wastes on growth and flowering of petunias which are an important U.S. flowering crop. Vermicomposts, produced commercially from cattle manure, food wastes and paper wastes, were substituted at a range of different conce...
A full scale swine (300 pigs) waste treatment system, including a solid/liquid separation unit (3 m) with a solids holding tank (1.2 m) and a liquid holding tank (20 m), two anaerobic reactors (10 m each) in series, an intermittent aeration unit (20 m), a sedimentation/polishing unit (20 m) and a sludge dewatering bed (17 m), was used to investigate the impact of integrating an intermittent aer...
