MFC-1 and 88.4%, 78.6% and 67.2% respectively in MFC-2.
The COD removal efficiency using dairy wastewater at 100%,
75% and 50% wastewater concentrations were 84.8%, 77.8%
and 72.1% respectively in MFC-1 and 86.42%, 81.7% and
75.2% respectively in MFC-2. This relative slow COD
removal was possibly due to less availability of biodegradable
substrate in 75% and 50% wastewater samples than that of full
strength wastewater leading to competitive inhibition in
microorganisms.
