Based on the circulating water quality and the treatment technology features in Huaneng Shang'an Power Plant

a simulation facility of reverse-osmosis(RO) has been designed

the static soak test and dynamic imitation test being carried out by using many kinds of bacteriside.Under condition of different bactericides containing in the inlet water

the recovery rate and desalination rate etc.of said simulation facility of reverse-osmosis have been analysed and studied

the influence of different bactericaides upon the performance of reverse-osmosis membrane being systematically evaluated.Results of study show that the developed green bactericide is suitable to power plants using RO desalting equipment to treat the blowdown circulating water

it not only can kill the bacteria in circulating water

but also can't affect the RO membrane;the bactericides

such as DCCNa and benzulconium chloride can't be used in this kind of power plant.
