Abstract
Residual scale inhibitors can cause water quality changes in circulating cooling process,thus affect the performances of reverse osmosis membrane. This study investigated the scale inhibition performance of scale inhibitors,PASP,HEDP and ATMP. The effects on the performance of reverse osmosis membrane were investigated by static test and dynamic test. Results showed that among PASP,HEDP and ATMP,the scale inhibition performances of PASP were best and scale inhibition rate could be as high as 84.21%. All the three materials had certain effects on the surface of the reverse osmosis membrane structure,composition and membrane flux. When the concentration of PASP, HEDP and ATMP was 50mg/L,10mg/L and 30mg/L respectively,the membrane flux decreased by 5.53%,4.89%,9.09%,less than 18.95% of the blank solution. In addition,desalination rates increased.关键词
