The purpose of this study was to quantify the occurrence and release of antibiotic resistant genes (ARGs) and antibiotic resistant bacteria (ARB) into the environment through the effluent and biosolids of different wastewater treatment utilities including an MBR (Membrane Biological Reactor) utility, conventional utilities (Activated Sludge, Oxidative Ditch and Rotatory Biological Contactors-RB...

Wastewater treatment systems collect and treat sewage that includes microplastics (MPs). However, we are not aware of any studies on the occurrence distribution MPs in wastewater stabilization ponds (WSPs), which serve small communities worldwide. Here, characterized (~45 µm–5 mm) an aerated WSP serving ~500 houses adjacent lake. Putative were most abundant duckweed (Lemna minor) sludge (75 ± 2...

Poultry waste is rich in organic matter, which allows its treatment by the process of anaerobic digestion (AD) to reinforce economic and environmental green strategies. The aim this study assess technical feasibility poultry AD semi-continuous mode intensify methane production co-digestion with physico-chemical sludge, i.e., product primary wastewater after slaughtering process. First, dropping...

The use of lime to reduce or eliminate pathogen content is a cost-effective treatment currently employed in many Class B biosolids production plants in the United States. A bench scale model of lime stabilization was designed to evaluate the survival of adenovirus type 5, rotavirus Wa, and the male specific bacteriophage, MS2, in various matrices. Each virus was initially evaluated independentl...

The paper presents research on the impact of adding various forms sorghum to sewage sludge anaerobic digestion process. use liquid alone in biogas plants at wastewater treatment is inefficient due low total solid (dry matter) content this substrate. tests revealed that production methane and amounted 17.9% (105.4 Nm3∙Mg−1, VS—volatile solid). Therefore, other substrates should be blended with i...

Experimental studies on the decontamination and stabilization of sludge sites sediment with calcium oxide treated disinfectant. The results research discovered that sewage Voronezh City is safe can be used as organic fertilizer for growing agricultural plants. Determination content macro-elements mineral nutrition in soil reaction its environment showed application fertilizers form increases am...

Liming is a cost-effective treatment currently employed in many Class B biosolids production plants in the United States. A bench scale model of lime stabilization was designed to evaluate the persistence of viral, bacterial and parasitic pathogens. The survival of fecal coliforms, Salmonella, adenovirus type 5, rotavirus Wa, bacteriophage MS-2, Cryptosporidium parvum oocysts, Giardia lamblia c...

1 This paper aims to compare household waste, separated pig solids, food waste, pig slaughterhouse sludge 2 and green algae regarding their biodegradability, their stabilization kinetics and their temperature rise during 3 composting. Three experiments in lab-scale pilots (300L) were performed for each waste, each one under a 4 constant aeration rate. The aeration rates applied were comprised b...
