Results showed that if only CPAM was added, the Zeta potential of the furnish changed little but CTR changed obviously. If the CPAM was added after the PAC, the dissolved charge of the furnish changed little while the Zeta potential changed more. That illustrated that the function of PAC and CPAM in the furnish system was different. PAC could eliminate the anionic trash but could not significantly increase the Zeta potential, which benefited the bridging flocculation of CPAM and reduced the consumption of CPAM.Read More
