Estimating microbial electrolysis cell (MEC) investment costs in wastewater treatment plants: Case study

摘要: Abstract Microbial electrolysis represents a new approach for harnessing the energy contained in organic matter of wastewater. However, before this can be implemented on practical basis, cost-effective manufacturing process microbial cells (MECs) must developed. The objective study is to estimate an acceptable purchase cost MEC reactor domestic wastewater treatment plant. We that full-scale operating at current density 5 A m −2 (amperes per square meter anode) and consumption 0.9 kWh kg-COD −1 (kilowatt-hour kg removed chemical oxygen demand (COD)), €1220 m −3 (euro m 3 anodic chamber) established as target which break-even point reached after 7 years.
