Membrane module that is currently being used in osmotic power generation is less osmotic flux, cannot remain current for practical use. Osmotic flux must be improved by confirming internal flow of membrane module because there is a need to improve the efficiency of osmotic power generation. But research on the internal flow of membrane module has not been so far. So concentration distribution and flow conditions are unknown. Therefore, visualize the flow by flowing dyes, investigate the flow properties and change in concentration by change in color due to concentration.
