Abstract
Improving the Performance of Constructed Wetland Microbial Fuel Cell (CW- MFC) for Wastewater Treatment and Electricity Generation
Highlights
Water is an important and critical resource required for industrial processes, food production, energy generation among other applications
The aim of this work is to examine the performance of constructed wetlands (CW)-microbial fuel cell (MFC) for wastewater treatment (COD removal) and electricity generation using electrodes made of grid stainless steel and compare it with another types of electrodes using plain stainless steel and graphite electrodes
In the second constructed wetland microbial fuel cell (CW-MFC) unit, the anode was stainless steel mesh (SSMa) while the cathode was a couple of stainless steel plain (SSPc) and the unit is referred to as (SSMa-SSPcCW-MFC)
Summary
Water is an important and critical resource required for industrial processes, food production, energy generation among other applications. The availability and quality of water is extremely affected by climate changes [1]. For this reason, wastewater could be treated and used as wash water or for reuse in green areas [2]. Physical and biological technologies are normally used for wastewater treatment These technologies are featured with considerable power consumption and relatively high cost. One of the extensive biological technologies which takes more attentions by the researchers is constructed wetlands (CW). It has been considered environment friendly and the most cost-effective technology used for this purpose [3]. The reactions that occur in two zones aerobic and anaerobic can be utilized for the implementation of microbial fuel cells (MFCs)
