| Summary: | An air-cathode MFC-adsorption hybrid system, made from earthen pot was designed and tested for
simultaneous wastewater treatment and energy recovery. Such design had demonstrated superior
characteristics of low internal resistance (29.3 O) and favor to low-cost, efficient wastewater treatment
and power generation (55 mW/m3) with average current of 2.13 ± 0.4 mA. The performance between
MFC-adsorption hybrid system was compared to the standalone adsorption system and results had
demonstrated great pollutants removals of the integrated system especially for chemical oxygen demand
(COD), biochemical oxygen demand (BOD3), total organic carbon (TOC), total volatile solids (TVS), ammoniacal
nitrogen (NH3-N) and total nitrogen (TN) because such system combines the advantages of each
individual unit. Besides the typical biological and electrochemical processes that happened in an MFC
system, an additional physicochemical process from the activated carbon took place simultaneously in
the MFC-adsorption hybrid system which would further improved on the wastewater quality. |
