  • What is cationic polyacrylamide?
  • Cationic polyacrylamide is a water-soluble polymer that is mainly used for sludge dewatering in municipal wastewater treatment plants. The major physical forms of polyacrylamide include powder, liquid, and emulsion or dispersions. The various end-users of polyacrylamide are water treatment, oil and gas, pulp and paper, mining, and other end-users.
  • Where are polyacrylamides used in New Zealand?
  • 1.6.3 Most polyacrylamides used in New Zealand for drinking-water treatment are manufactured in the USA, Europe and Australia. Polyacrylamides are normally dosed directly to water from a mixing or day tank via a positive displacement metering pump.
  • How many polyacrylamide production facilities does SNF Australia have?
  • We operate 21 production facilities, including 7 global integrated sites, across Europe, Australasia, and the Americas, which account for almost half of the world’s polyacrylamide production. SNF Australia is the market leader in polymer technology and application in Oceania for water and wastewater treatment.
  • How much cationic polyacrylamide should be used for sludge treatment?
  • For sludge treatments, consumption of a cationic polyacrylamide of 5.4 g·kg −1 of total solids is found to be the best economical solution . Several studies were made, following life cycle analyses, to evaluate energy consumption of wastewater treatment (e.g., Tillman et al. , Hospido et al. and Wenzel et al. ).
