Resumen de: AU2023279503A1
There are closed systems of growing microalgae but as they are not able to produce algal biomass economically they are very few and far between and are only used to grow microalgae for very expensive produce. These closed systems also require large space. The result of the lack of economic closed systems is why almost all algal biomass production currently uses raceway ponds. This invention integrates a new compact, very economic and highly productive closed system of growing microalgae including good parameter control with carbon sequestration from say a coal fired power plant or organic waste management in a way that makes the whole process financially attractive and cyclic and if desired it could be made carbon negative. The compact nature of this invention allows algal farms to be sited next to most sources of carbon dioxide.
