QAC BASED DISINFECTANT
DBNPA is a highly effective, environmentally friendly biocide. It provides a quick kill while also quickly degrading in water. The final end product is carbon dioxide and ammonium bromide.
Chemical name: 2,2-dibromo-3-nitrilopropionamide
Compatibility with other water treatment chemicals and water conditions: DBNPA is compatible with other treatment chemicals with the exception of mercaptobenzothiazole. It also is not compatible with ammonia or hydrogen sulfide-containing water. DBNPA maintains reliable control in systems running at acidic, neutral, or alkaline pH.
Degradation in water: DBNPA degrades quickly in aqueous environments. At neutral pH, its half-life is about nine hours (Exner, Burk, and Kyriacou: Rates and Products of Decomposition of 2,2-dibromo-3-nitrilopropionamide, J. Agr. Food Chem., Vol. 21, 1973, pp. 838–842). Continuous biocide release by the tablet maintains concentrations effective for control in the tower, while the biocide in the blowdown discharge degrades quickly. So it's easy to meet strict environmental regulations on tower discharge. Is DBNPA an oxidizer?
DBNPA is not an oxidizing biocide and it is not a bromine release biocide.
DBNPA does act similar to the typical halogen biocides.
