Abstract

For the reduction of energy consumption at a mega–ton scale SWRO plant, pressure–retarded osmosis (PRO)system is proposed in the Mega–ton Water Project. The PRO system recovers power from salinity gradient between the concentrated brine from the SWRO plant and fresh water from regional waste water treatment facility. PRO performance of cellulose triacetate hollow–fiber membrane modules was examined in a prototype PRO plant and the test operation was carried out for more than one year.We have reached the maximum output power density, 13.3 W/m2, using 10–inch module at our prototype PRO plant in Fukuoka and 17.1W/m2 in the laboratory–scale experimental using 5–inch module between tap water and concentrated brine (Ca.7%). These results indicate that a commercial PRO plant could be available in very near future.
