  • Why is DBNPA used as a biocide in industrial water applications?
  • World J Microbiol Biotechnol. 2025; 38 (5): 82. 2,2-Dibromo-3-nitrilopropionamide (DBNPA) has been used as a biocide in industrial water applications due to its instantaneous antimicrobial activity and rapid chemical breakdown.
  • What is DBNPA used for?
  • DBNPA, a quick kill broad spectrum biocide used to control microbial, fungal and algal growth in industrial water system such as cooling towers, reverse osmosis membranes, evaporative condensers, pulp and papermill effluents oil-recovery systems, metal-cutting coolants, air-conditioning systems.
  • Can DBNPA be used for potable water production?
  • The use of DBNPA is prohibited from inline application for potable water production, due to the harmful toxicity of the hydrolysis byproducts ( Blanchard et al. 1987; Baker & Dudley 1998; Bertheas et al. 2009 ).
  • How does DBNPA decompose in water treatment applications?
  • In particular, DBNPA decomposition in water treatment applications is dominated by two reaction pathways: pH-dependent hydrolysis and light-catalyzed reactions with reducing nucleophiles [ 11 ]. However, the relevance of these pathways in ethanol processes and operations is not known.
