• The toxicity reduction evaluation of water reclamation using medaka and a gree algais needed for safe applications for landscaping. In this study, toxicity reduction of wastewater by nanofiltration (NF) and reverse osmosis (RO) membranes was evaluated based on algal growth inhibition test by using microplates and short-term toxicity test on embryo and sac-fry stages of medaka fish. NF and RO membranes reduced chronic toxicity to algal growth. While reclamation by RO membrane reduced toxicity to medaka on embryo and sac-fry stages, NF membrane did not reduce the toxicity in the experimental conditions in which the concentration of ammonia was high.
