Use: DBNPA is organo-bromine biocide. DBNPA is a fast, high-efficiency biocide, widely used in paper & pulp, industrial water treatment systems, industrial cooling water systems, air washer systems, membrane systems for industrial water, metal working fluids containing water, oil field applications.
We also produce liquid form and customize DBNPA tablet.
DBNPA Features:
1. Normally, DBNPA kills microorganism fast, it works in 20 minutes.
2. It is cost effective. Low using concentration has good effect on killing bacteria, fungus, algae.
3. Suitable for remove bacterial mucus.
4. Biodegradable and environment- friendly product. There is a little residue in treated system. The decomposed products are carbon dioxide, ammonia, & bromide ion.
5. Compatibility with standard water treatment system.
6. Compatibility with membrane.
7. DBNPA could control Legionella. DBNPA shot dosed at 2-5ppm active is proven to control legionella in the planktonic phase with a contact time of 2-3 hours. DBNPA shot dosed at 10-15ppm active is proven to control both planktonic and sessile legionella colonies with a contact time of 4-6 hours. DBNPA dosed to maintain a constant level of 1-2ppm active is proven to be effective at controlling legionella in the planktonic and sessile phase.
Above dosage is only for your reference, please use it based on degree of contamination of your system.
8. Increasing cooling water alkalinity presents a problem for most water treatment biocides. However, for DBNPA even at higher pH values, rapid & effective microbial control is achieved before any significant degradation occurs.
