To avoid the limitations of single biofouling control methods, this study proposed the synergistic therapy of quorum quenching (QQ) and traditional but essential physical cleanings (i.e., backwashing and gas sparging) to cost-effectively manage membrane biofouling of anaerobic membrane bioreactors (AnMBRs). QQ reduced content of proteins in the extracellular polymeric substances (EPS) of suspended biomass (solid… Continue reading Significance of integrated therapy of biological and physical cleaning for biofouling control and energy saving in AnMBRs
This study assesses the performance of waste sugarcane bagasse ash (SBA)-based ceramic membrane in anaerobic membrane bioreactor (AnMBR) treating low-strength wastewater. The AnMBR was operated in sequential batch reactor (SBR) mode at hydraulic retention time (HRT) of 24 h, 18 h, and 10 h to understand the effect on organics removal and membrane performance. Feast-famine… Continue reading Performance of Anaerobic Membrane Bioreactor (AnMBR) with Sugarcane Bagasse Ash-based Ceramic Membrane treating Simulated Low-strength Municipal Wastewater: Effect of Operation Conditions
This study was carried out with the scope of resource recovery platform from the food waste-based organic materials in the presence of in situ microfiltration immersed anaerobic membrane bioreactor. Afterwards, ultrafiltration technology was adopted. These microfiltration and ultrafiltration processes successfully removed larger particles, i.e., suspended solids from the anaerobically digested effluent. Moreover, ultrafiltration membranes (50 kDa)… Continue reading Microfiltration and Ultrafiltration as Efficient, Sustainable Pretreatment Technologies for Resource Recovery
Various methods exist for the recovery of volatile fatty acids from organic mixed waste effluents, and among them, the membrane filtration process holds a great promise over other recovery methods due to their simplicity, sustainability and high efficiency. Hence, in this study, nanofiltration experiments were carried out using two commercial nanofiltration membranes of 200–300 Da… Continue reading Feasibility of nanofiltration process for high efficient recovery and concentrations of food waste-derived volatile fatty acids
The potential of organic waste streams (i.e., food waste) for the sustainable production of precursor chemicals such as volatile fatty acids (VFAs) using anaerobic digestion (AD) has received significant attention in the present days. AD-derived VFAs have great market appeal if the challenges with their recovery and purification from the complex AD effluent is overcome.… Continue reading Double-stage membrane-assisted anaerobic digestion process intensification for production and recovery of volatile fatty acids from food waste
