How does DBNPA work?

The chemical formula of DBNPA is: DBNPA is an advantageous disinfectant since it also quickly degrades to carbon dioxide, ammonia and bromide ion when in an aqueous environment. This allows the effluent to be safely discharged even in sensitive water bodies.

Is DBNPA an oxidizer?

DBNPA may be considered an oxidizer, since the bromine component can oxidize bacterial substrates. DBNPA is typically supplied as a 20% or 5% active solution. Dose rate is 25 to 35 mg/L for 5% active material.

How do you dissolve DBNPA?

The former medicine of DBNPA is white crystalline solid, without special odor, and fusing point 123-125 DEG C.Be slightly soluble in water (25 DEG C, 1.5g/100g water), be dissolved in the organic solvents such as ethanol, acetone, benzene, polyethylene glycol and DMF.

What is Dbnpa biocide?

DBNPA or 2,2-dibromo-3-nitrilopropionamide is a quick-kill biocide that easily hydrolyzes under both acidic and alkaline conditions. It is also used as slime control on papermachines, and as a biocide in hydraulic fracturing wells and in cooling water.

Why are biocides added to cooling tower water?

Biocides are used to control bacteria in cooling water systems. Failure to implement a good cooling water biocide program may lead to bacteria and under deposit corrosion. Under deposit corrosion occurs when bacteria occurring within the water system. Under this bacteria, corrosion occurs.

What is biocidal action?

According to the Biocides Directive (98/8/EC), biocidal products are intended to destroy, render harmless, prevent the action of, or otherwise exert a controlling effect on any harmful organism by chemical or biological means.

Is biocide a chemical?

Biocide is a chemical substance or microorganism intended to destroy, deter, render harmless, or exert a controlling effect on any harmful organism by chemical or biological means. Biocides are one of the most commonly used techniques in industry to kill bacteria in the system because of the rapid response.

How is DBNPA compatible with other water treatment chemicals?

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.

What does DBNPA stand for in a biocide?

DBNPA Biocide. DBNPA is a highly effective, environmentally friendly biocide. It provides a quick kill while also quickly degrading in water.

What is the half life of DBNPA in water?

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).

What kind of acidic conditions does DBNPA hydrolyze to?

DBNPA or 2,2-dibromo-3-nitrilopropionamide is a quick-kill biocide that easily hydrolyzes under both acidic and alkaline conditions.
