  • Can acrylamide based flocculants be used in oil sands extraction?
  • A representative example comes from the effluents (tailings) of oil sands extraction process that contain high solids organic-contaminated fine clays, where the use of conventional acrylamide-based flocculants does not meet the dewatering criteria needed by this industry. 3
  • Who bought polyacrylamide flocculant?
  • Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).
  • How effective is polymer-assisted flocculation?
  • Most recent studies on polymer-assisted flocculation have reported exponentially decreasing settling profiles, indicating a high flocculant effectiveness. The slope of the initial linear part of the settling profile is called the initial settling rate (ISR), which determines the initial recovery of clean water from a suspension.
  • Can polycarbonate & polyacrylic acid be used for flocculation?
  • When employing each polymer specifically, Al Dawery demonstrated that combining a blend of polycarbonate and polyacrylic acid for flocculation results in improved liquid clarity. The combination of flocculants could raise the sludge volume index by 70%, compared to 40% in the case of polycarbonate alone.
