This presentation is about a semi-permeable membrane composing an ocean-based photobioreactor (PBR) to culture the microalgae in seawater. For a photobioreator floating on the ocean, it is necessary that semipermeable membrane (SPM) which is possible that nutrients in ocean were diffused into PBR, but not microalgae inside PBR leaked to outside. But commercially available membranes are not suitable because of insufficient ion permeability and expensive cost. In this reason, we proposed new fabric-hydrogel composite membranes (FHCMs). We also introduced micro-pores in FHCMs matrix by using a particulate-leaching method to enhance ion permeability. In the permeability measurement of ions, the porous FHCMs reached higher result compared with a commercially semipermeable membrane. These results suggest that the porous FHCMs have potential in the application of microalgae culture for bio-diesel production in a marine environment. |
