Abstract：A rotating disk was introduced into the complexation-ultrafiltration process to strengthen the filtration of manganese-containing wastewater and maleic acid-acrylic acid copolymer (PMA) was selected as the complexing agent to investigate thoroughly the shear stability of PMA-Mn complex formed by PMA and Mn(Ⅱ). The test results show that with the best complexing condition for PMA and Mn(Ⅱ), including pH value of 6 and P/M (mass concentration ratio of complexing agent to metal ion) of 12, the retention rate of Mn(Ⅱ) can reach 99.1%. When the pH value is 4, 5, and 6, respectively, the decomplexation of PMA-Mn can be occurred at critical speeds of 800, 1 200, and 1 400 r/min, with the corresponding critical shear rates at 5.32×104, 1.10×105, and 1.47×105 s-1. It is shown that PMA can be efficiently regenerated by shear-induced decomplexation.
