  • Can cationic microblock structure improve sludge neutralization and electrical patching?
  • It was speculated that this phenomenon was caused by the cationic microblock structure in TPAMD. It could greatly improve the ability of electric neutralization and electrical patching. The surface charge and electrostatic repulsive force of sludge colloid particles would be rapidly reduced at a relatively small dosage.
  • Why is cationic fragment structure important in a template copolymer?
  • The cationic fragment structure in the template copolymer could help to generate large and dense floc structure and form stable drainage channels. Under external pressure, these large and compact floc structures had greater compressive resistance, which avoided deformation and blockage of drainage channels and voids.
  • How cationic microblock structure is formed on tpamd molecular chain?
  • An evident and continuous cationic microblock structure was formed on TPAMD molecular chain through MV-TP. The microblock structure had higher positive charge density, thus having strong charge neutralization, excellent electrical patching, and higher positive charge utilization efficiency.
  • Does cationic microblock structure improve sludge floc formation?
  • Obviously, TPAMD with cationic microblock structure corresponded to the largest D f of 1.51, which indicated that cationic microblock structure could help to form more compact sludge flocs (Wilén et al. 2003; Wang et al. 2011). The cationic microblock structure significantly improved the ability charge neutralization and electrical patching.
