In order to design efficient fouling mitigation strategies in granular anaerobic membrane bioreactors (G-AnMBR), foulant characteristics and their role have be thoroughly investigated. Raw mixed liquor of G-AnMBR was split by sieving into granules supernatant fractions at 0.125 mm. Then, the potential reversibility different samples (granules, raw liquor) were assessed measuring critical fluxes...

The main objective of this study was to evaluate the anaerobic conversion of vinasse into biomethane with gradual increase in organic loading rate (OLR) in two upflow anaerobic sludge blanket (UASB) reactors, R1 and R2, with volumes of 40.5 and 21.5L in the mesophilic temperature range. The UASB reactors were operated for 230 days with a hydraulic detection time (HDT) of 2.8d (R1) and 2.8-1.8d ...

Aerobic granular sludge (AGS) with oversized diameter commonly affects its stability and pollutant removal. In order to effectively restrict the particle size of AGS, a sequencing batch reactor (SBR) spiny aeration device was put forward. A conventional SBR (R1) an (R2) treating tannery wastewater were compared in laboratory. The result indicates that from R2 smaller than R1 granulation. spines...
