Abstract

Activated Sludge Process is widely used to treat wastewater biologically due to low running cost, high degradation efficiency and efficient removal of organic and inorganic compounds. However, the process will produce considerable amount of excess sludge and various handling methods can cost up to 50% of wastewater treatment plant operation cost. Anaerobic Digestion (AD) has been recognized as the best stabilization process for excess sludge due to energy recovery via methane production, odorless sludge production and pathogen destruction ability. Two major problems for AD in sludge solids reduction and methane production are biological hydrolysis stage as rate limiting step and the inability of anaerobic microbes to further digest the sludge mass trapped by cell membranes (extracellular polymeric substances).
