Application Area: Drinking Water Purification Background: A municipal water treatment facility in Southern Europe implemented poly-DADMAC as a primary coagulant for surface water clarification. Regulatory authorities require strict monitoring of residual DADMAC monomer in finished drinking water due to potential health considerations. Challenge: The facility needed to verify that residual DADMAC levels in treated water remained within safe limits after poly-DADMAC application, while maintaining effective turbidity removal. Solution: Using DADMAC-based polymer as the primary flocculant, the facility conducted comprehensive residual monomer testing. Advanced analytical methods (reversed-phase ion-pair chromatography with mass spectrometry) were employed for ultra-trace quantification without complex sample pretreatment. Results: Testing of distributed drinking water samples revealed DADMAC concentrations ranging from 1.2 to 3.8 µg/L, with a mean value of 1.7 µg/L—well below the regulatory thresholds. The analytical method achieved a Limit of Quantification of 0.42 µg/L and a Limit of Detection of 0.12 µg/L, with recovery rates between 80-120%. Conclusion: When properly formulated and applied, DADMAC-based polymers deliver effective flocculation and clarification while maintaining exceptionally low residual monomer levels in finished water, meeting stringent EU and US drinking water standards.
