the
literature provides more detailed information on this aspect
[17,35]. However, this pseudo, apparent Ks is able to provide useful
information on the relationship between substrate concentration
and current density in the MXC. For instance, the simulation with
Eq. (1) predicts 3.9 A/m2 for effluent SCOD of 26 mg/L (only 9%
error). Hence, this pseudo, apparent Ks can be used for a design
parameter of MXCs.
