This presentation is about a semi-permeable membrane that constitutes an ocean-based photobioreactor. For effective cultivation in the marine environment, it is necessary to use membranes of high nutrient ion permeability for efficient cultivation and mechanical strength to withstand a harsh marine environment. But commercially available membranes are not suitable for mass culture because of insufficient ion permeability and expensive cost. In this reason, we propose new fabric-hydrogel composite membranes (FHCMs) made of 2-hydroxyethyl methacrylate, cross-linker and fabric. We also introduce 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 and FHCMs. These results suggest that the porous FHCMs have potential in the application of microalgae culture for bio-diesel production in a marine environment. |
