| Abstract: | A kind of scale inhibitor used in reverse osmosis systems has been studied to prevent scaling on the membrane. Aspartic acid is pyrocondensed to form polysuccinimide which reacts with taurine to form polyaspartic acid graft copolymer. Polyaspartic acid graft copolymer, PBTCA and dispersant are compounded to form this kind of scale inhibitor used in reverse osmosis systems. The rate of scale inhibition of the polymer is determined by static and dynamic scale inhibition tests. The results show that the compound has excellent scale inhibition and dispersion performances. It is a kind of scale inhibitor used in reverse osmosis systems especially suitable for the water with high hardness in North China. |
