DB 20

DB20 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 issimilarwith famous brand AQUCAR RO-20 and Aqucar DB 20 etc.

4. Key Benefits

4.1 DB 20 water treatment microbiocide is a fast-acting biocide.

4.2 DB 20 rapidly decomposes in aquatic environments with only carbon dioxide,ammonia,and bromide ions remaining as end products.

4.3 DB 20 is compatible with chlorine

4.4 DB 20 is completely miscible with water and easily dispersed upon introduction into a water system.

4.5 DB 20 is a broad spectrum antimicrobial,effectively controlling fungi,yeast,bacteria and algae.

5.Applications and Use

5.1 –Recirculating water cooling towers

Intial Dose: 0.05%-0.10%

Subsequent slug doses: 0.01-0.03%

5.2 –Pulp,paper and paperboard mills

Heavily fouled systems should be cleaned before treatment is begun.

5.3 –Enhanced oil recovery systems

a: Add intermittently for 4 to 8 hours per day, and from 1 to 4 times per week,or as needed depending on the severity of contamination.

b: Add continuously until the desired degree of control is achieved.
c: Add continuously or as needed to maintain control

5.4 Use with Biopolymers

Add 15-80 ppm of DB 20

6.Storage

25kg/200kg PE drum. A shelf life of 1 year is expected if material is stored in sealed original packaging.
