textile wastewater contains substantial pollution loads in terms of chemical oxygen demand (cod), biological oxygen demand (bod), total suspended solids (tss), total dissolved solids (tds) and heavy metals. phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (amats) is well established environmental protective technique. a lab scale stud...

decolorization of aqueous solutions containing ionic dyes (reactive blue 19 and acid black 172) by a tfc commercial polyamide nanofilter (nf) in a spiral wound configuration was studied. the effect of operating parameters including feed concentration (60-180 mg/l), pressure (0.5-1.1 mpa) and ph (6-10) on dye removal efficiency was evaluated. the response surface method (rsm) was utilized for th...

the present work studied the application of membrane bioreactor (mbr) for tapioca wastewater processing that contained chemical oxygen demand (cod) ranging from 4000-9000 mg/l. a preliminary study was initially conducted in order to evaluate membrane performance with respect to its flux with mlss concentration ranging from 4,500 to 10,500 mg/l. it was clear that fouling was observed during the ...

background: conventional wastewater treatment is a combination of physical and biological processes designed to remove organic matter from solution. waste sludge drawn from these processes is thickened and processed for ultimate disposal wastewater contains various kinds of infectious agents, such as bacteria, viruses, fungi and parasites. correct treatment in wastewater treatment plants is imp...

Dairy industry wastewater is rich in organic content, presenting a high biodegradability, and therefore biological treatments are widely employed. This study aimed to evaluate biosolids production three systems: activated sludge (AS), movingbed biofilm reactor (MBBR), sequencingbatch (SBMBBR). Simulated dairy was used at different load rates (OLRs): 1.22, 2.87, 5.44 gCOD L−1d−1. Besides product...

This study explores antibiotic resistance genes (ARGs) as emerging environmental contaminants. The purpose of this study was to investigate the occurrence of ARGs in various environmental compartments in northern Colorado, including Cache La Poudre (Poudre) River sediments, irrigation ditches, dairy lagoons, and the effluents of wastewater recycling and drinking water treatment plants. Addition...

Dairy wastewater (DWW) contains large amounts of mineral and organic compounds, which can accumulate in soil water causing serious environmental pollution. A constructed wetland (CW) is a sustainable technology for the treatment DWW small-medium sized farms. This paper reports two-year study on performance pilot-scale horizontal subsurface flow system Sicily (Italy). The CW covered total surfac...

Water pollution caused by population growth and human activities is a critical problem exacerbated limited freshwater resources increasing water demands. Various sectors contribute to pollution, with the dairy industry being significant contributor due high concentrations of harmful contaminants in wastewater. Traditional treatment methods have been employed, but they limitations terms effectiv...
