“…Bioenergy produced during wastewater treatment can help offset the costs of operation and increase self-sufficiency. During the past years, various methods thus have been developed to exploit wastewaters for energy recovery and simultaneously realize their environmentalfriendly treatment: upflow anaerobic sludge blanket (UASB) [4], expanded granular sludge bed (EGSB) [5], anaerobic submerged membrane bioreactor (AnSMBR) [6], anaerobic baffled reactor [7], etc.…”

The use of liquid fraction of pressed municipal solid waste (LPW) for hydrogen production was evaluated via electrohydrogenesis in a single-chamber microbial electrolysis cell (MEC). The highest hydrogen production (0.38 ± 0.09 m 3 m -3 d -1 and 30.94 ± 7.03 mmol g -1 COD added ) was achieved at an applied voltage of 3.0 V and pH 5.5, increasing by 2.17fold than those done at the same voltage without pH adjustment (pH 7.0).Electrohydrogenesis was accomplished by anodic oxidation of fermentative end-products (i.e. acetate, as well as propionate and butyrate after their acetification), with overall hydrogen recovery of 49.5 ± 11.3% of COD added . These results affirm for the first time that electrohydrogenesis can be a noteworthy alternative for hydrogen recovery from LPW and simultaneous organics removal. Electrohydrogenesis efficiency of this system has potential to improve provided that electron recycling, electromethanogenesis and deposition of nonconductive aggregates on cathode surface, etc. are effectively controlled.

“…Using gas sparging as the fouling control strategy, it was reported that energy consumption of AnMBRs is 2485 to 12,275 kJ/m 3 of wastewater treated, which is alone higher than energy consumption in CAS-WWTPs [33]. Alternatively, UASB integration with membrane internally and externally was explored in pilot-scale level [45,46]. TCOD removal efficiencies as high as 87-90% were reported.…”

Anaerobic-Based Water Resources Recovery Facilities: A Review

The concept of water resources recovery facilities (WRRFs) has gained more attention as a more sustainable substitute for the conventional activated sludge-based wastewater treatment plant (CAS-WWTPs). Anaerobic treatment is advantageous due to its lower energy use, limited sludge production, and higher recovery of the soluble chemical oxygen demand (sCOD) from the received wastewater. In this article, a critical review of the proposed scheme for the anaerobic-based WRRF (An-WRRFs) is presented which is preceded with discussion of CAS-WWTPs limitations. In addition, the evolution of anaerobic treatment from being viewed as wastewater treatment plant (WWTP) to WRRF is demonstrated. It is attained that, even though anaerobic WWTPs (An-WWTPs) have simple and low energy mainline and very limited sludge handling process, its limited removal and recovery capacity have been widely reported, especially in cold weather. On the other hand, in the An-WRRF, higher energy expenditures are employed by using membranes, dissolved methane recovery unit, and primary treatment (extra sludge handling). Yet, energy recovery in the form of biogas is notably increased, as well as the removal efficiency under moderate residence times. The three key challenges to be overcome are the low value of biogas, reducing the energy use associated with membranes, and maintaining high performance in full-scale, especially in cold weather.

“…Membrane fouling reduces permeate flux or increases the trans membrane pressure (TMP) depending on the operation mode. In anaerobic membrane systems, biogas sparging is extensively used for fouling control and significant enhancement in operation time, and reductions in sludge cake formation have been reported [21][22]. The main drawback of biogas sparging is its operational cost due to the elevated energy consumption that prevents the widespread application in membrane bioreactors [23][24][25].…”

Domestic and industrial wastewaters are characterized by high organic content along with other diverse pollutants. Modern wastewater management comprises efficient removal of pollutants and gain energy to fulfil the discharge standards, protect the environment and sustain economic development. Until the last few decades, aerobic treatment technologies were dominant in wastewater treatment. Despite efficient treatment, large energy consumption for aeration, high operational cost and production of a great amount of sludge are the main drawbacks of aerobic systems. Wastewater treatment by anaerobic biological processes has many advantages over aerobic and other removal systems [1]. In addition to higher organic matter removal with less nutrient requirement, lower sludge production and energy-rich methane (CH 4) production are the main outcomes of anaerobic technologies. Various individual and combined anaerobic reactor systems have been successfully applied for the treatment of wastewater [2-5]. Anaerobic bioreactors contain a diverse microbial community, and slow-growing methanogens are very sensitive to changes in environmental conditions. In order to achieve the high treatment performance
