  • 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.
  • Can activated starch polymers be used in ballasted flocculation?
  • These results indicate that activated starch polymers represent a promising alternative to the use of PAM polymers in a ballasted flocculation process. ballasted flocculation, microsand, polyacrylamide, starch, turbidity You do not currently have access to this content.
  • Can activated starch be used as a coagulant aid for alum?
  • Polyacrylamide-based polymers are commonly used as coagulant aids in water treatment, but there is some concern about their potential toxicity. This work investigated a novel alternative, Hydrex TM 3841 activated starch polymer, as a coagulant aid for alum to treat low turbidity source water at pilot scale using in-line filtration.
  • How much alum does activated starch need?
  • Compared to two typical polyacrylamide-based polymers, Magnafloc® LT22S and Superfloc® A-100, at an alum dose of 0.95 mg Al/L, activated starch could reach a similarly optimal unit filter run volume (∼116 m³/m²), while the required dose (0.48 mg/L) was approximately 2–10 times higher than those for the other two types of polymers.
