Fresh water resources are under tremendous stress throughout the globe. Many areas all along the developing or even developed nations indicated, the fresh waters are greatly contaminated by the discharge of untreated sewage/industrial effluents and even variety of toxins entering naturally. Environmental regulations and public health concerns stated that wastewaters collected from municipalitie...

• A comparison of three different analytical proposals for the analysis PPCPs in sewage sludge was presented. clean-up step essentially preceded by extraction technique UAE. direct injection UAE extract with no prior LC-MS/MS provided best performance. The resulting method validated and successfully applied dewatered digested samples. Acetaminophen reported concentrations above 1,000 ng g −1. T...

The effects of thermal-alkaline pretreatment on dewatered activated sludge (DAS) solubilisation and subsequent high-solid anaerobic digestion were studied by response surface methodology (RSM) from 105 to 135 °C and between 5 and 35 mg alkaline/g total solid (TS) DAS. Soluble chemical oxygen demand (SCOD), soluble carbohydrates, and protein concentrations were significantly enhanced in thermal-...

As one of the primary nodes in flow micro-plastics (MPs) environment, it is critical to examine and assess Sewage Treatment, occurrence, removal MPs waste treatment plant (WWTP). This research explored shape, size, composition at various stages WWTP process south city Hefei, China, dry rainy weather conditions, as well effectiveness a three-stage process. The collected were quantitatively quali...

Fermentor-stabilized activated sludge from an industrial beverage bottling plant was grown on three different food sources: normal plant waste water, plant wastewater containing high sucrose concentrations, and a synthetic glucose-based feed stock. Surface charge, hydrophobicity, and exopolysaccharide composition were measured on the stabilized bacterial flocs. Cell surface charge was measured ...
