  • Is activated starch an alternative to polyacrylamide based polymers?
  • Activated starch as an alternative to polyacrylamide-based polymers for in-line filtration of low turbidity source water Dual starch–polyacrylamide polymer system for improved flocculation Water Res., 124 ( 2017), pp. 202 - 209, 10.1016/j.watres.2017.07.044 J. Environ.
  • What is starch-G-poly acry1amide-co-acrylic acid?
  • Starch-g-poly(acry1amide-co-acrylic acid) copolymers have potential use as flocculants and a structural similarity to saponified starch-g-polyacrylonitrile, which functions as both a thickener for aqueous systems2 and as an absorbent for water.3 Unmodified Globe corn starch was from CPC International and contained 10-14% HzO.
  • Why is anionic polyacrylamide chosen?
  • Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
  • Can activated starch polymer replace Pam during ballasted flocculation?
  • This study identified the conditions favorable to the use of an activated starch polymer as an alternative to PAM during ballasted flocculation: mixing intensity and time, coagulation pH, ballast size and chemical composition, and polymer charge density.
