Environmental performance of microbial fuel cell based live sludge for voltage production and congo red dye removal

Abstract EN

In this work, Single chamber Microbial fuel cells (SCMFCs) are a versatile technology is depends on the interaction mechanisms of bacteria, to produce bioelectricity simultaneously and treat Congo red (CR) dye from aqueous solution at different pH (6.5-8).

Electricity generation from the biodegradable organic substrate (sucrose) accompanied by decolorization of azo dye was investigated in the batch test results showed that more than 99% decolorization demonstrated at UV-Visible Spectrophotometer (500 nm) was achieved within 20 days and maximum output voltage (889 mv) had been obtained in an open circuit at a pH value of 7.5.

Microbial community analysis showed that species in live sludge and the impact of bacteria grown on removal and voltage.
