The application of the expanded granular sludge bed (EGSB) reactor for the anaerobic treatment of low-strength soluble wastewaters using ethanol as a model substrate was investigated in laboratory-scale reactors at 30oC. Chemical oxygen demand (COD) removal efficiency was above 80% at organic loading rates up to12 g COD/L . d with influent concentrations as low as 100 to 200 mg COD/L. These res...

Understanding of the metabolic pathways connected with a removal micropollutant bisphenol A (BPA) may help to better design effective wastewater treatment processes. The aim this study was determine changes in gene expression an aerobic granular sludge (AGS) community exposed BPA. In study, AGS adapted BPA degradation used. sludge, dosed; as control sample, granules without addition were mRNA i...

Structural changes during sludge treatments impact flowability and raise severe technical issues. In this study, the consistency is analysed using thread rolling test. Transition from pasty to granular-like material occurs at a total solid (TS) content of 43 wt%. A granular rheometer used characterize sludge's over wide range TS content. The typical powder-like behaviour recorded whatever conte...
