Abstract: The integrations of wastewater treatment and microalgaebased biofuel have attended considerable. This review paper describes the overview of microalgae in terms of biofuel productivity, cultivation of microalgae, harvesting microalgae and method for converting microalgae biomass to biofuel productions. The species of microalgae mostly used for cultivating in the wastewater to produce biofuel are presented. There are two major systems for cultivating microalgae: 1) opened system (raceway, circular and unmixed pond) and 2) closed system (photobioreactor, tubular and flat plate). The suitable selection of harvesting method is very critical because it can reduce the overall cost. Microalgae can be harvested by flocculation, flotation, filtration and gravity and centrifugal sedimentation. In the present paper, the energy conversion process is explained and can be classified into thermochemical and biochemical conversions. Microalgae biomass can be converted into bio-oil, ethanol, methane, biodiesel and syngas. The selection of the conversion process depends on the species of microalgae, the final productivity and the possible economic factor.
