The effect of several heavy metal ions on the generation of methane in anaerobic digestion was studied using synthetic wastewater with variable conenctrations of the ions.
The experimental results showed that the amount and the yield of methane production as well as the specific growth rate of cells were decreased as the concentration of the ions were increased. The specific growth rate of exponential growth phase was found to be expressed by a modified Monod equation containing an inhivition factor, a junction of the ions. And the lag time increment due to heavy metal ions was also expressed as a function of the concentration.
