Abstract
In recent year, excess sludge anaerobic digestion by various types of pre-treatment processes have become of high interest. An energy point of view, the most effective technology of pre-treatment processes is Thermal Hydrolysis Process(THP). It was considered as a pre-treatment technique to improve biosolid properties because of the solubilization of particulate organics and promotion of biogas generation. In this study, in order to evaluate the effects of changing organic carbon compounds from THP under a various temperature were measured and analysed using Liquid Chromatography-Organic Carbon Detection(LC-OCD). Results showed that the efficiencies of sludge solubilization and low molecular weight(Mw < 500g/mol) organic carbon formation increased with the increase of the reaction temperature and oxidizer.
