Membrane bioreactor (MBR) is a reliable and promising technology for wastewater treatment and reuse. However, since membrane fouling and energy consumption still remain operational obstacles and challenges for the widespread application of the MBR technology, research studies for fouling control are still underway. Recently, among different integrated approaches for membrane fouling mitigation, the combinations of… Continue reading An electro moving bed membrane bioreactor (eMB-MBR) as a novel technology for wastewater treatment and reuse
Recently, microbial fuel cells (MFCs) have been integrated with membrane bioreactors (MBRs), either in an internal or an external configuration, for wastewater treatment and energy recovery. In an external configuration, MFCs could be applied for an efficient sludge reduction since they can simultaneously address energy issue and environmental concerns associated with sludge treatment. In the… Continue reading Microbial fuel cell technology as a downstream process of a membrane bioreactor for sludge reduction
The increasing application of membrane filtration in water and wastewater treatment necessitates techniques to improve performance, especially in fouling control. Ultrasound is one promising technology for this purpose as cavitational effects facilitate continuous cleaning of the membrane. This research studied the ultrafiltration of lake water in systems with constant permeate flux under medium frequency (45… Continue reading Control of fouling formation in membrane ultrafiltration by ultrasound irradiation
Reclamation and reuse of wastewater is one of the most effective ways to alleviate water resource scarcity. In many countries very stringent limit for chlorination by-products such as trihalomethanes has been set for wastewater reuse. Accordingly, the use of alternative oxidation/disinfection systems should be evaluated as possible alternative to chlorine. Recently ultrasound (US) was found… Continue reading Wastewater disinfection by combination of ultrasound and ultraviolet irradiation
