Modelling biodiesel production from microalgae, using industrial wastewater as a growth medium

ABSTRACT This paper presents a mathematical model validated with experimental data for the analysis of biodiesel production from microalgae biomass, using as an alternative substrate industrial wastewater. System dynamics methodology was used for its development, by which the mathematical model repr...

System dynamics methodology was used for its development, by which the mathematical model representing the production of biomass and lipids was obtained, as well as the generation of biodiesel from microalgae oil. Biomass generation was represented by a basic growth model which assumes that there is no restriction for nutrients. This biomass generates a quantity of lipids according to the nitrogen-phosphorus ratio present in the industrial effluent, with higher production under low nitrogen concentration. Finally, these lipids are transformed into an amount of fatty acid methyl-ester that varies at a rate of transesterification. Validation and calibration of model behavior, was performed with experimental data obtained in tests of the Scenedesmus sp. microalgae growth in wastewater from the textile and tanning industry. The simulation of the model represented with significant approximation the growth and the generation of lipids for Scenedesmus sp. Furthermore, it was shown that wastewater from tanneries would allow increased production of biodiesel by favoring the generation of biomass rich in amount of lipids.
