  • Is poly-DADMAC a coagulant?
  • Author to whom correspondence should be addressed. Deceased. Poly-DADMAC (PD) is a commonly used organic polymer in water treatment, known for its effectiveness as a coagulant. However, its presence as a residue in water raises concerns related to membrane fouling and the potential formation of carcinogenic compounds.
  • What is PolyDADMAC used for?
  • PolyDADMAC is used in waste water treatment as a primary organic coagulant which neutralizes negatively charged colloidal material and reduces sludge volume compared with inorganic coagulants. PolyDADMAC is used for controlling disturbing substances in the papermaking process.
  • Can poly-DADMAC be quantified in coagulation treatment samples?
  • Quantification of Poly-DADMAC in Coagulation Treatment Samples The method’s applicability in practical field conditions was assessed by determining residual PD concentrations in cyanobacteria-contaminated water and cowshed effluents during coagulation and clarification treatments.
  • What aqueous solution is used for PolyDADMAC?
  • Experiments were conducted using nanopure water (Milli-Q, Millipore, USA). Commercial polyDADMAC (aqueous solution, 20 wt%) was purchased from Sigma Aldrich (St. Louis, MO, USA) and was diluted to 2 g/L with nanopure water. Solution pH was adjusted using phosphate.
