Objectives Effluents contain a diverse abundance of antibiotic resistance genes that augment the resistome of receiving aquatic environments. However, uncertainty remains regarding their temporal persistence, transcription and response to anthropogenic factors, such as antibiotic usage. We present a spatiotemporal study within a river catchment (River Cam, UK) that aims to determine the contrib...

the river kabini which is tributary of cauvery drains through industrial area at nanjangud, karnataka. out of the sediment load carried by the river, 2micron the clay fraction was analyzed for total heavy metal contents and advanced statistical techniques such as cluster analysis and correlation matrix were applied in order to investigate the source of heavy metal concentration in the sediments...

Abstract The present study aims to fill the data gap analysis in urban wastewaters characteristics Benin and its statistical analysis. Physicochemical parameters such as pH, electrical conductivity (EC), Chemical Oxygen Demand (COD), Biochemical (BOD5), Total Kjeldahl Nitrogen (TKN), Phosphorus (TP) UV Absorbance at 254 nm, were determined on domestic (greywater blackwater) industrial (hospital...

The paper is a review of some current practices in the treatment and disposal of the more important fermentation industry effluents. Reference is made to the production of whisky and other potable spirits, malt, beer, vinegar, yeast, cider, antibiotics and vitamins. The most important means of treating distillery effluents is by recovering the soluble and some insoluble material in the liquid r...

Dilution factors are a critical component in estimating concentrations of so-called "down-the-drain" chemicals (e.g., pharmaceuticals) in rivers. The present study estimated the temporal and spatial variability of dilution factors around the world using geographically referenced data sets at 0.5° × 0.5° resolution. Domestic wastewater effluents were derived from national per capita domestic wat...

In order to evaluate the efficacy of constructed wetlands for treatment of domestic wastewater for small communities located in rural areas, small-scale wetland mesocosms (400 L each) containing two treatment designs (a mixture of Typha, Scirpus, and Juncus species; control without vegetation) were planted into two depths (45 or 60 cm) with pea gravel. Each mesocosm received 19 L/day of primary...

The characterization of landfill leachate has been well established. However, its biodegradation properties have not been well reported. Therefore, this research was undertaken to investigate the biodegradability of semi-aerobic sanitary landfill and the ratio of the biological oxygen demand (BOD) to chemical oxygen demand (COD) BOD5/COD, COD fraction on leachate from Pulau Burung landfill Site...

The adoption of decentralized sewage treatment systems appears as an alternative for regions lacking sanitary infrastructure. Regarding Brazilian municipalities, they presented, in 2020, a collection service rate the urban population equal to 63.2%. Also, according data from National Sanitation Information System, municipality Aracaju, capital state Sergipe, generated is only 53.5%. Due this re...

there is a great interest in developing rapid analytical methods and provide appropriate parametersfor quantitative analysis of compounds derived from refractory pollutants. such methods are important forroutine quality control analysis of an effluent before being discharged into the environment. therefore, a rapid methodology for identification and quantification of some aliphatic acids is pro...

In Peru, many effluents from domestic wastewater treatment plants often contain high concentrations of biological, physical or chemical contaminants; constituting low quality effluents. this context, the aim research was to evaluate effect produced by bacterial strain Pseudomonas putida ATCC 49128 on variation biochemical oxygen demand (BOD5) extracted plant (WWTP) located in town Collique, dis...
