Description:
DBNPA 20% water treatment microbiocide is an aqueous formulation containing a 20% w/w concentration of DBNPA (2,2-dibromo-3-nitrilopropionamide).It is a broad spectrum biocide offering rapid control of bacteria, fungi, yeast and algae. DBNPA is a non-oxidizing and highly effective biocide with proven performance in the past 5 decades. Korel DB 20 is similar to Aqucar RO-20 and Aqucar DB 20 etc.
