Increasing awareness of the energy–environment centers leads to the development of new technologies that have a direct impact on energy production and consumption during environmental remediation. Bioelectrochemical system (BES) is anticipated to be the emerging technology for the simultaneous removal/recovery of resources such as energy, nutrients, water, and heavy metals. Organic compounds inside the leachate are oxidized by micro-organisms which in turn lead to the production of energy and other value-added resources. Through the integration of membrane process such as forward osmosis in BES will help to recover the high-quality water for applications like agricultural. Recovery of metals is largely affected by uncertainty in concentration but still recovery of metal is achievable in leachate. Phosphorous and ammonia can be recovered through cathode reduction reactions driven by electricity generation. Low bioavailability of landfill leachate is one of the major challenges for BES which can be improved through proper pretreatment of landfill leachate. Another challenge of achieving the metal recovery from leachate is the low concentration of heavy metals. System scaling up remains as a great confront, especially for BES as energy production and consumption balance needs to be well understood. This review paper identified the key challenges, opportunities, and future recommendations for the recovery of resources from leachate using BES.

To date, there is no central wastewater (WW) treatment plant in Erbil city, Kurdistan region, Iraq. Therefore, raw WW disposes to the environment and sometimes it used directly for irrigation in some areas of Erbil city. Disposal of the untreated WW to the natural environment and using for irrigation it causes problems for the people and the environment. The aims of the current work were to study the characteristics, design of primary and different secondary treatment units and reusing of produced WW. Raw WW samples from Ashty city-Erbil city were collected and analyzed for twenty three quality parameters such as Total Suspended Solids (TSS), total dissolved solids, total volatile and non-volatile solids, total acidity, total alkalinity, total hardness, five-day Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), biodegradability ratio (BOD5/COD), turbidity, etc. Results revealed that some parameters such as BOD5 and TSS were exceeded the standards for disposal of WW. Design and calculations for primary and secondary treatment (biological treatment) processes were presented. Primary treatment units such as screening, grit chamber, and flow equalization tank were designed and detailed calculation were illustrated. While, Conventional Activated Sludge (CAS), Sequencing Batch Reactor (SBR) and Moving Bed Biofilm Reactors (MBBR) were applied for the biological treatment of WW. Results revealed that MBBR was the best and economic technique for the biological treatment of WW. Treated WW is suitable for reusing and there is no restriction on use for irrigation of green areas inside Ashty city campus.
