The increasing concern for environmental management promotes the development of new products and processes, aiming for economic progress with environmental protection. Through the cultivation of microalgae, photosynthetic organisms that convert water, CO2 and light into oxygen and biomass, able to produce an unlimited amount of biocompounds. Factors such as temperature, pH, type of system and culture medium used are essential for its development and biomass composition. These microbes can not only absorb inorganic matter from the effluent and assimilate these nutrients for its growth, minimizing the cost of nutrient addition, but also absorb CO2 in the atmosphere or flue gas through photosynthesis Thus, this work presents a review on the cultivation of microalgae using wastewater as a source of nutrients generating compounds with industrial interest and biotechnological applications besides a computational fluid dynamics (CFD) modeling for CO2 reduction aiming the scale-up. The use of wastewater for the cultivation of microalgae has been studied for years, as well CO2 mitigation, however, there is still much to be explored to obtain greater use of waste; and together with the increasing of CFD technique applied for bioprocess, they can contribute for process optimization, scale-up and improvements in the environment.
