Physical characteristics of the sludge in a complete retention membrane bioreactor

Aerobic Membrane Bioreactor for Wastewater Treatment – Performance Under Substrate-Limited Conditions

“…This behaviour is commonly accepted in the literature (e.g. Pollice et al, 2007). Therefore, the following equation (Eq.…”

In-situ integration of microbial fuel cell with hollow-fiber membrane bioreactor for wastewater treatment and membrane fouling mitigation

“…The sludge in the MFC-MBR had lower values of CST and SRF than the C-MBR (Table S1), inferring that the sludge in the MFC-MBR had better filterability (Pollice et al, 2007). The improvement of the sludge filterability demonstrated that the sludge might be modified in the MFC-MBR.…”

Sludge filterability and dewaterability in a membrane bioreactor for municipal wastewater treatment

“…Sludge dewaterability was found to be very close to that of conventional activated sludge, regardless with the increasing suspended solids [14,15]. Concerning the apparent viscosity, there is a common consensus on the non-Newtonian thixotropic behaviour of the MBR sludge and most studies indicate an increasing trend with the MLSS concentration, generally better fit by the Ostwald model [15,16]. However, the interpretation about the actual impact of such higher viscosity on the energy demand of the process is still debated.…”
