  • What are acrylamide and polyacrylamide used for?
  • Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 °C for elongated time.
  • Is acrylamide biodegradable?
  • Acrylamide is subject to biodegradation in both soil and surface water. Acrylamide in environmental water had to be removed by conventional water treatment processes; however, treatment with ozone or potassium permanganate may decrease acrylamide concentration.
  • How much Acrylamide is in drinking water?
  • The United States used 65% of the produced PAM for water treatment in 1991. The guidelines set by the World Health Organization (WHO) and EU for residual acrylamide concentration in drinking water are 0.5 and 0.1 μg/L, respectively. The US EPA requires the water supplier to notify them when acrylamide is added to water.
  • Are acrylamide flocculants safe for drinking water?
  • Considering drinking water, both flocculants dose and free acrylamide monomer levels in polyacrylamide flocculants should be limited and kept under control when using for water treatment purposes. The global ecological risk posed by acrylamide is still uncertain since longer-term studies are deficient.
