Abstract: Desalination plant equipped with reverse osmosis modules has been used for fresh water preparation for low energy consumption. Reverse osmosis modules, however, become dirty increasing with changing of running hours and desalinating performance of module if decrease. The most important problems on the desalination plant are that how to refresh modules by various chemical materials and how to be lengthen the durability of modules. Then, we have studied to fluctuate of module performance by washing method using citric acid for modules on the desalination plant (7m³/day) installed in T/V Kakuyo-Maru for 3 years from 1986 to 1989. We came to the following conclusions: i) The washing by citric acid is hightly effective to refresh modules when codition of module do not be excessive compacted. ii) Desalination plant equipped with reverse osmosis module dependent on the inlet water pressure. When inlet pressure of water is increased desalinated performance being a good condition. Namely, amount of desalinated water is increased and desalting ratio of module is improved.
