DBNPA 20 for Reverse osmosis special fungicide CAS 10222-01-2


Product Name: 2.2-Dibromo-3-Nitrilopropion Amide 20% Solution

CAS No.: 10222-01-2

DBNPA-20 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. DBNPA-20 is a class of non-oxidizing biocides used to control microbial special biocides in reverse osmosis membrane systems.

The active ingredient of DBNPA-20 is a formulation having a 2,2-dibromo-3-nitropropionamide (DBNPA) content of 20%. DBNPA-20 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.

Features

DBNPA-20 fungicide is a water-soluble formula. The rational use of this fungicide can bring many advantages to the reverse osmosis membrane system:

1. Non-oxidizing bactericide, does not affect the stability of chemical and physical structure of reverse osmosis membrane

2, fast sterilization speed, low concentration

3. Extensive killing of bacteria, fungi, yeast and algae microorganisms

4, the original liquid is added directly, easy to use

Application

DBNPA-20 has been widely used in industrial water and reverse osmosis and papermaking water systems, and is effective against bacteria, fungi, yeasts, blue-green algae and other algae even at low concentrations. The bactericidal active ingredient can act immediately after entering the aqueous phase of the reverse osmosis membrane system. Because of its extremely rapid sterilization, it can greatly reduce or even completely eliminate the proliferation of microorganisms and the biofilm formed by the surface of the reverse osmosis membrane and the inlet channel. At the same time, its rapid degradability minimizes environmental concerns. It is important to note that when DBNPA-20 is applied to a reverse osmosis membrane system, it is largely repelled by the composite membrane and the residual amount at the drain end is very low.

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. In the DBNPA-20 environment, Vancide-DBNPA-20 can be quickly decomposed. The rapid bioavailability of Vancide-DBNPA-20, combined with rapid chemical decomposition, is the most economical way to eliminate microbial contamination with minimal impact on the finished product. Vancide-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.

Storage: It can be stored for 12 months under normal temperature conditions.
