DBNPA 20 Biocide   CAS 10222-01-2 

Fast acting, broad spectrum biocide for treating raw materials, process water, and contaminated products and systems

General

DBNPA 20% biocide algicide offers broad spectrum control of bacteria, fungi and algae.It is quick-acting and breaks down rapidly into non-hazardous materials. Active Ingredient 2,2-Dibromo-3-nitrilopropionamide (DBNPA).

Specifications

Chemical properties

The active ingredient of DBNPA 20 is a formulation having a 2,2-dibromo-3-nitropropionamide (DBNPA) content of 20%. DBNPA 20 biocide is effective at very low concentrations and can kill bacteria, fungi and yeast on a broad spectrum. DBNPA 20% antimicrobials are completely miscible with water and are therefore easily dispersed into the system. Effective sterilization is usually achieved in just a few minutes, rather than a few hours.

Applications

DBNPA 20% solution reverse osmosis special fungicide is a fast-acting broad-spectrum fungicide. For reverse osmosis membrane desalination systems that utilize industrial wastewater, seawater, and other surface waters containing microbial sources as a source of water, biocontamination of membrane fouling is a ubiquitous problem. The incompatibility of chlorine gas and other oxidizing biocides commonly used in water treatment with polyamide reverse osmosis limits the use of such bactericides. DBNPA20 fungicide is a class of non-oxidizing biocides used to control microbial special biocides in reverse osmosis membrane systems.

Use concentration

1. Online addition of industrial water (circulating cooling water):

Continuous addition, recommended dose is 2-10ppm

2. Off-line cleaning of industrial water:

Depending on the amount of total solution in the feed water tank, 200 ppm to 400 ppm of DBNPA-20 was added. After the completion of the aqueous solution transfer, the cells are circulated or inactivated for 1 to 3 hours to ensure that all of the reverse osmosis membrane modules are in sufficient contact with DBNPA 20 solution. In this environment, DBNPA-20 can be quickly decomposed. Its rapid bioavailability combined with rapid chemical decomposition, is the most economical way to eliminate microbial contamination with minimal impact on the finished product. 

DBNPA-20 generally kills 99% before it is fully resolved to lose its effectiveness. After the cleaning process, start flushing with water. The water circulation flushing process recommends draining the water from the three systems to ensure that the biocide solution is thoroughly rinsed from the entire reverse osmosis system.

Note:

Do not add DBNPA-20 to the influent water of a reverse osmosis system that still has sodium bisulfite or other reducing agents. The addition of various reducing agents must be suspended at least 15 minutes prior to the addition of DBNPA-20 to avoid loss of facial active ingredients.

Product Benefits

Stability

It is stable under normal conditions. Avoid process temperatures of 70°C (158°F) or higher and the use of strong reducing agents.

Handling

Please refer to the safety data sheet of this product for precise handling instructions. The processing and use of industrial chemicals require adequate technical and professional knowledge.

In general, avoid eye and skin contact, wear safety goggles, gloves and protective clothing. In case of eye or skin contact, despite precautionary measures, wash immediately and thoroughly with plenty of warm water and obtain medical attention. Vapors, including cyanogen bromide, may be present in unvented containers. These vapors may be irritating to the upper respiratory tract of workers, who allow their mouth or nose to get close to the container opening.

Packing：25Kg per drum, 250Kg per drum or 1250Kg per IBC drum.
