The present invention relates to a process for pretreatment of a feedstock in a pretreatment tank. Various parameters, such as oxidation-reduction potential, pH, and temperature, are monitored in the pretreatment tank to determine whether the oxidation-reduction potential, pH, and temperature are each within a predetermined range. The volume of feedstock inside the pretreatment tank is adjusted in response to a determination that one of the oxidation-reduction potential, pH, and temperature of the treated material are outside the corresponding predetermined ranges to maintain the oxidation-reduction potential, pH, and temperature of the treated material within operating conditions. |
