“…MFC integrated with any unit operations or processes have the privilege of combining the advantages of each unit as compared to the standalone MFC [7]. Several studies have been done on MFChybrid system recently and a comprehensive comparison of these systems were done in terms of operating temperature, pollutant removal efficiency, MFC design, source of inocula, substrate and economics feasibility and presented in Table 3.…”

“…There were many studies done on the typical standalone two-chambered MFC because such design is very easily constructed and typically suitable for lab scale studies. Nevertheless, standalone treatment system has limitation such as less wastewater treatment efficiency as compared to the MFC hybrid system [7]. Much studies had demonstrated the ability of hybrid MFCs in removing various types of pollutants present in the wastewater such as chemical oxygen demand (COD) [8][9][10], phosphorus [11], dye [12,13], suspended solids (SS) [10], total nitrogen (TN) [14], ammonia nitrogen (NH 3 À ÀN) [15,16], and so on.…”

“…However, to the best knowledge of the authors, the studies of the effect of temperatures had only been done on these few sources which includes beer brewery wastewater [33], domestic wastewater [34][35][36], sanitary wastewater [37], barley processing wastewater [38] and synthetic wastewater [39,40]. Municipal water treatment experiments which were done previously at low temperatures (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15) C) could also be used as a source of high potential MFC operation for electricity generation [41]. At present, none has come to understand the effects of temperature with palm oil mill effluent (POME) as a substrate to MFC which is known as the major contributor of the pollution loads in the rivers in countries such as Malaysia and Indonesia.…”

A B S T R A C TA cost effective single-chamber microbial fuel cell (MFC) integrated with adsorption system was tested under different operating temperatures to observe pH profiles, organics, solids, nutrients, color and turbidity removal and power density generation. The optimum operating temperature range was found to be $25-35 C with majority of the removals achieved at $35 C. Maximum power density recorded was 74 AE 6 mW/m 3 with coulombic efficiency (CE) of 10.65 AE 0.5% when operated at 35 C. Present studies had successfully demonstrated the effectiveness of a hybrid system in removing various types of pollutants in POME at optimum temperature and able to fulfill the stringent effluent discharge limit. Chemical oxygen demand (COD), total solids (TS) and turbidity removals increase linearly with temperatures with removal efficiency of 0.5889% C À1 , 1.0754% C À1 and 0.7761% C À1, respectively. The temperature coefficient (Q 10 ) is found to be 1.06, 1.45 and 1.09, respectively. Besides, MFC-adsorption hybrid system had demonstrated superior stability over a wide range of operating temperatures in terms of COD removal as compared to the non-integrated MFC system.

“…The system may be a combination of several processes and operational units in order to improve the quality of the wastewater effluent, with energy advantages [38]. In Brazil, the annual volume of wastewater treated is 2.6 billion cubic meters (81% of the wastewater collected in the network), consuming 802 million kWh/year, or 0.24 kWh/m 3 [39].…”

Abstract:Wastewater treatment is a process of intensive use of resources, mainly energy, which accounts for 15 to 40% of the operating costs in conventional wastewater treatment systems. With the expected demographic increase and the restrictive trend in quality standards for effluent discharge, the energy consumption tends to increase further if there are no changes in the processes. The literature gathers the energy consumption of different wastewater treatment systems, in an attempt to map the processes and to help the decision making in the search for better alternatives. One of these alternatives is the recovery of energy from the sewer. The conventional treatment system requires between 0.3 and 0.6 kWh/m 3 , while the energy contained in the wastewater may be up to 10 times of the one required for the treatment. The simultaneous wastewater treatment and power generation, called the hybrid treatment system, is a worldwide trend. In Brazil, recent studies have shown, through energy balances, the energy viability of anaerobic-aerobic systems, with the production of algae. This work presents a comparative review of the energy consumption of different wastewater treatment plants, aiming at a better understanding and management of the processes. The results showed that there are few Brazilian data published, indicating that the country still demands more studies on the subject to improve its processes. In the treatment of wastewater, most studies point to the aerobic process as the largest consumer of energy, and efforts are focused on the optimization of the conventional system, but still without great achievements. Environmental goals and water supply strategies are poorly integrated with the energy handling, leading to an inefficient use, and with economic and environmental consequences.

“…There are many types of industrial wastewater based on the different industries and contaminants; each sector produces its own particular combination of pollutants. Wastewaters are typically contaminated with physical, chemical and biological composition which has tremendous negative impact on environment, where it has the ability to destroy many animal habitats, and cause irreparable damage to many ecosystems [3].…”

-The main concept of wastewater treatment is to remove or reduce the excessive amounts of contaminants from the wastewater. This performance study was needed to evaluate the efficiency of a wastewater treatment plant in decreasing the pollutants level, to meet with the governmental environmental standards. Also, the wastewater re-use for irrigation approaches must be in accordance with the criteria along with indicators should be monitored also impended up on a complying basis, and necessity at the stage of assessing and development to give top precession to standards to shield the land and water resources along with the public health protection Required category of treatment determent through the development of treatment objectives of the approach and check all applicable laws and regulations and finally compared the characteristics of the wastewater with the constraints of the laws. And thereby determine and consider possible options, disposal and re-use. Next decide the most acceptable option is to get rid of pollutants in the wastewater in ways that are either chemical or physical or biological individually or grouped. This study evaluates and analyzes the performance and the efficiency of Shoubra Al Khaima (Balqus) wastewater treatment plant (WWTP). Based on the results, it shows that Balqus WWTP operates with removal efficiencies higher than 90% for biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS) and oil & grease (O&G) were established. This analysis applied to define a performance measuring plan based on the most important parameters that can be reliable and applicable for any WWTP.
