| description | Constructed wetland (CW) and microbial fuel cell (MFC) complement each other
well due to the similar configuration in both systems. Therefore, incorporation of
CW and MFC had emerged in years ago, which is known as CW-MFC. In contrast to
the standalone systems, the integrated system had a higher wastewater treatment
(WWT) efficiency with simultaneous bioelectricity generation. In this context, the
open circuit and closed circuit CW-MFCs were developed to compare the
effectiveness of CW-MFC and CW in this study. The performance of CW-MFC
varied with the configuration and operating condition that affect the complex
mechanisms in the system. This study aims to optimise the CW-MFC system for
optimum removal efficiency of chemical oxygen demand (COD) and power
generation. A few aspects that were considered in this study include the electrode
material, the hydraulic retention time (HRT), and the external resistance. The
respective effect was analysed. Waste materials, namely copper wire and iron strip
were employed in this study. The CW-MFC with the former electrode material had a
higher treatment efficiency. The effect of HRT was then investigated by varying
from 1 d to 7 d. Subsequently, the optimal external resistance was determined among
the resistors of 110 Ω, 560 Ω, and 1000 Ω. The findings show that the copper CWMFC achieved the most outstanding performance on day 7 when it was externally
connected to the smallest resistance. By applying the optimum operating condition,
the system removed an average of 85.1 % COD from the municipal wastewater and
generate a power density of 40.3 mW/m2
. The total cost of this study was RM 200.80.
This highlights that utilisation of waste material as the electrode form a cost-effective
viii
and more sustainable CW-MFC system for treating the wastewater and producing the
bioelectricity concurrently.
