Abstract:A new municipal wastewater treatment flowsheet was developed with the objectives of energy sustainability, and water and nutrient recovery. Energy is derived by shunting a large fraction of the organic carbon in the wastewater to an anaerobic digestion system. Aerobic and anaerobic membrane bioreactors play a key role in energy recovery. Phosphorus and nitrogen are removed from the wastewater and recovered through physical-chemical processes. Computer modeling and simulation results together with energy balanc… Show more
“…AnMBRs can also play a vital role in energy recovery due to their capacity to produce CH4 from the utilization of a large fraction of organics in wastewaters [40]. It has great potential to achieve energy recovery and better quality effluent for reuse.…”
In this review paper, Anaerobic Membrane Bioreactor (AnMBR) is considering as highly efficient and reliable technology for organic material removal from wastewater with no additional energy requirement for aeration. AnMBR is a combination of conventional anaerobic technology and modern membrane system. AnMBR is cost effective alternative technology with pros of anaerobic microbial activity because Methogenic microorganism can convert organic pollutant load of wastewater into renewable energy in the form of methane rich biogas, this conversion is mainly done by transformation of organic matter into energy by high chemical oxygen demand (COD), total suspended solid (TSS) and pathogens removal. Methane rich biogas can be used as a storable source of supplemental energy for the production of heat or power thus AnMBR technology provides improved effluent quality, reliability, and efficiency over the other traditional technologies. This review paper is included the overview of AnMBR, the advantages over other wastewater treatment technology, operational constraints and the concerned factors that has affected the performances of implemented systems, applications of AnMBR for various types of wastewaters, research and development summary and future perspective for further research.

“…One of such hybrid systems is designed by coupling anaerobic fermentation and Microbial Fuel Cell (MFC) techniques with the conventional activated sludge process, thus enabling the energy recovery from sewage or sewage sludge (Ma et al, 2013;McCarty et al, 2011). Some innovative approaches have been investigated to explore the innovative treatment flow-sheets with respect to the resource recycling and reuse (Kelley et al, 2009;Sutton et al, 2011). For instance, Kelley et al (2009) developed a hybrid system for organic carbon and struvite recovery (Ma et al, 2013).…”
Section: Hybrid Approaches Of Nutrient Recoverymentioning
“…There is a wide variety of possible alternatives, as the array of technical options grows. While water, energy and nutrient recovery (phosphorus and nitrogen) are known alternatives (Doyle and Parsons, 2002;Daigger, 2008Daigger, , 2009McCarty et al, 2011;Sutton et al, 2011;Garcia-Belinchón et al, 2013;Lee et al, 2013;Puchongkawarin et al, 2015), other options are emerging, e.g. the recovery of cellulose fibers (Ruiken et al, 2013), biopolymers (Tamis et al, 2014), bioplastics (Kleerebezem and Van Loosdrecht, 2007) and protein (Matassa et al, 2015).…”
a b s t r a c tResources are becoming scarce. Therefore, reuse of resources is becoming more and more attractive. Wastewater can be used as a resource, since it contains many resources like organic matter, phosphorus, nitrogen, heavy metals, thermal energy, etc. This study focused on the reuse of organic matter and phosphorus from Amsterdam's wastewater. There is a wide variety of possible alternatives, and the technical options are growing. The problem is not the availability of technology for resource recovery, but the lack of a planning and design methodology to identify and deploy the most sustainable solutions in a given context. To explore alternative, coherent and viable strategies regarding resource recovery from Amsterdam's wastewater chain, the development process of dynamic adaptive policy pathways was used. In the first phase a material flow analysis was made for Amsterdam's wastewater chain and analyzed for water, organic matter and phosphorus. In the second phase measures were identified and characterized. The characterization was based on criteria focusing on changes in material flows, recovered products and implementation horizon. For the Amsterdam case recovered products concerned alginic acid, bioplastic, cellulose, phosphorus and biogas. In the third phase the measures were combined into strategies, which are combinations of measures that focus on a specific goal of resource recovery. For the Amsterdam case this resulted in four strategies: a strategy focusing on production of alginic acid, a strategy focusing on production of bioplastics, a strategy focusing on recovery of cellulose, and a strategy focusing on recovery of phosphorus. Adaptive policymaking showed to be a good approach to deal with the wide variety of possibilities and uncertainties. It resulted in a coherent policy as the resource recovery goals became clear, a flexible policy as the lock-in, no-regret and win-win measures could be identified, and an up-to-date policy as a periodic update is possible that will reveal new chances and risks.
