DB 20 water treatment microbiocide is an aqueous formulation containing a 20% w/w
concentration of DBNPA(2,2-dibromo-3-nitrilopropionamide) which is a broad
spectrum, fast acting control of bacteria,fungi,yeast and algae, also known as
DBNPA – a non-Oxidizing and highly effective biocide with proven performance in
the past 5 decades. DB 20 is similar with famous brand AQUCAR RO-20 and Aqucar DB
20 etc.
