Abstract

Concentración de cultivos de microalgas por un proceso de eliminación osmótica del medio utilizando disoluciones de glicerol.#La presente invención consiste en concentrar cultivos de microalgas mediante un proceso económico y de bajo consumo energético pudiendo reaprovechar el glicerol residual de la síntesis de biodiesel.#La disolución de glicerol constituye la solución osmótica, que se pone en contacto con el cultivo de microalgas a través de una membrana semipermeable. La diferencia de presión osmótica entre el cultivo y la disolución de glicerol hace que el agua se transfiera al glicerol, lográndose así, sin adición de químicos ni gasto energético adicional la concentración del cultivo.#Este procedimiento, permite que en los procesos posteriores al cultivo de microalgas se manejen menores volúmenes, con el subsecuente recorte en el gasto de equipos, suministros y energético.#Alternativas: centrifugación, floculación, ósmosis con agua de mar.Concentration of microalgae cultures by an osmotic elimination process of the medium using glycerol solutions. # The present invention consists in concentrating microalgae cultures by means of an economical and low energy consumption process being able to reuse the residual glycerol from biodiesel synthesis. Glycerol solution constitutes the osmotic solution, which is brought into contact with the microalgae culture through a semipermeable membrane. The difference in osmotic pressure between the culture and the glycerol solution causes the water to transfer to the glycerol, thus achieving, without the addition of chemicals or additional energy expenditure, the concentration of the crop. # This procedure allows the post-cultivation processes of microalgae smaller volumes are handled, with the subsequent cut in the cost of equipment, supplies and energy. # Alternatives: centrifugation, flocculation, osmosis with seawater.
