  • 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 are the physical and chemical properties of polyDADMAC?
  • The physical and chemical properties of polyDADMAC were then studied under simulated water treatment conditions. The polymer reaction with chlorine revealed the formation of trihalogenated methane compounds (THMs). Gas chromatography– mass spectrometry (GC–MS) was used to conclusively identify the formation of chloroform.
  • What conditions affect the stability of polyDADMAC with water treatment chemicals?
  • The results obtained for stability studies of polyDADMAC with water treatment chemicals such as chlorine, different conditions of pH, temperature and UV radiation are presented. Changes in the polymer structure was followed by GPC, HPLC and GC-MS and the results indicate that the product is affected by the above conditions.
  • 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.
