The feasibility of using intermittent cycle extended aeration system (ICEAS) sludge as a lipid feedstock for biodiesel production was investigated. The main effects of in situ transesterification parameters, reaction temperature (30-70°C), reaction time (4-24 h), catalyst concentration (1-5% volume/volume), and proportion of methanol to dry sludge (5-25 mL/g) at five-levels as well as their simultaneous interactions were evaluated to develop an empirical model. Optimized conditions were obtained at 60°C, 4.65% (volume/volume) H2SO4, 17.84 h reaction time, and 5:1 methanol to dry sludge proportion (ml/g), leading to a maximum of 18.58% (weight/weight) biodiesel yield with 94.23% fatty acid Me ester content. This result was higher in comparison with yields derived from conventional activated sludge, membrane bioreactor and anaerobic-anoxic-oxic processes. The ICEAS technol. advantages are owned to its different configurations leading to production of one blended sludge, shorter hydraulic retention time and higher COD to nitrogen ratios. The predominance of fatty acid Me esters such as palmitic, oleic, palmitoleic, stearic, linoleic and myristic acid Me ester, in the obtained biodiesel, indicated suitability of ICEAS sludge as feedstock for biodiesel production
