Membrane bioreactor (MBR)technology has been employed in sewage sludge treatment within polyhydroxyalkanoate (PHA) production systems to tackle challenges like sustainable recovery of volatile fatty acids (VFA) and achieving high-quality effluent. Typically, MBRs utilize pressure-driven membranes, mainly ultrafiltration (UF) membranes. Despite its advantages, membrane fouling remains a significant hurdle, particularly when scaling up from laboratory-scale to… Continue reading Improving Recovery of Valuable Bio-Products from Sewage Sludge Using Innovative Membrane Technologies
In the context of the circular economy and sustainability goals, there is a pressing need to recover valuable resources, such as clean water, biofuels, and biofertilizers, from wastewater. Membrane bioreactor (MBR) technology has emerged as a leading solution for advanced wastewater treatment, ensuring high removal efficiency for both conventional and emerging contaminants while also enhancing… Continue reading Innovative Membrane Bioreactors for Advanced and Sustainable Wastewater Treatment
Membrane bioreactors (MBRs) play a crucial role in wastewater treatment, but they face considerable challenges due to fouling. To tackle this issue, innovative strategies are needed. This study investigated the effectiveness of membrane reciprocation and quorum quenching (QQ) to control fouling in MBRs. The study compared MBRs using membrane reciprocation (30 rpm) and QQ (injecting media… Continue reading Membrane reciprocation and quorum quenching: An innovative combination for fouling control and energy saving in membrane bioreactors
The study has investigated the use of an Algae-Sludge Membrane Bioreactor (AS-MBR) for wastewater treatment. Its performance, in terms of pollutant removal and membrane fouling mitigation, was compared to that of a previously reported conventional MBR. Results showed that it has a COD removal efficiency that is only slightly higher than that in the conventional… Continue reading Wastewater Treatment and Membrane Fouling Control Using an Algae-Sludge Membrane Bioreactor (AS-MBR)
The effect of addition of algae to activated sludge as active biomass in membrane bioreactors (MBRs) and electro-MBRs (e-MBRs) for wastewater remediation was examined in this study. The performances of Algae-Activated Sludge Membrane Bioreactor (AAS-MBR) and electro Algae-Activated Sludge Membrane Bioreactor (e-AAS-MBR) were compared to those observed in conventional MBR and e-MBR, which were previously… Continue reading Wastewater treatment and fouling control in an electro algae-activated sludge membrane bioreactor
The rising of greenhouse-gas emissions (GHG), during the last 200 years, is associated to the well known global warming phenomena. One of the main sources of CO2-equivalent GHGs emissions are the environmental protection plants accounting for 1.57% of the global emissions and thus sustainable and effective technologies for their mitigation are strongly needed. The current… Continue reading Innovative membrane photobioreactor for sustainable CO2 capture and utilization
