Production and characterization of biodiesel from microalgae cultivated in municipal wastewater treatment plant.

摘要

ABSTRACT The combination of microalgae – based biofuel with municipal wastewater treatment has major advantages. The study aims to figure out the ability of producing biodiesel from High Rate Algal Pond (HRAP) constructed to treat municipal wastewater. Facultative algal pond followed by (HRAP) were designed and constructed in sewage wastewater treatment plant Zinin, Giza. The removal efficiency of COD and BOD of facultative pond was 57% and 59.6% respectively. The COD & BOD removal percentage decreased to -50% after HRAP this could be explained by the algal production. The results showed that oil content of biomass collected from HARP was 5% and the biodiesel yield was 70.9%. The fractions of biodiesel produced contained variety of fatty acids such as Palmitic, Oleic and linolenic acids..
