Abstract

A generalized kinetic model for the hydrothermal oxidation of organic matter in biological wastewater treatment sludge was developed using a simplified first-order reaction scheme. Forty eight hydrothermal treatment experiments using three sets of inflow conditions were performed. The activation energy divided by the gas constant (Ea/R) was represented by a linear function that increased in the range of 3900 (1/K) to 4400 (1/K) as a function of temperature in the range of 180°C to 263°C. The kinetic model developed was used to evaluate the technical feasibility of utilizing hydrothermal treatment as a sludge management option.
