There exist a number of studies on the application of oxidation-reduction potential (ORP) measurement as a new parameter in the analysis and control of waste treatment processes, but little has been done on the relation between ORP and metaene fermentation.In this experiment we have tried to make a time-potential curve for a thermophilic digester continuously fed with butanol-acetone stillage.During this experiment, it is suggested that ORP stabalized at(-330 mV) produced a suitable digestion of the waste.ORP stability if strictly correlated not only with the rate of gas production, but also with the shortening of the lag period of gas production. Rapid stabilization of ORP produced a shorter lag period which in turn produced a more complete digestion of the waste. This effect is obtained by repeated acclimation.The rate of digestion can also be stimulated in the same manner by addition of a dried activated sludge, even if acclimation is insufficient. It can be considered that the results obtained in the analysis of time-potential curve of digestion process have an interesting bearing on elucidation of the stimulating effect of dried activated sludge for methane fermentation.
