EKO POWER 520 Superior DBNPA Based Biocide

EKO POWER 520 is a high-performance biocide containing 50% 2,2-dibromo-3-nitrilopropionamide (DBNPA). It is specifically formulated to address microbial contamination in reverse osmosis (RO) systems, effectively targeting bacteria, fungi, and algae, including coliform and E. coli.

What is DBNPA ?


It is understood in the membrane industry that thin film composite polyamide membranes have limited resistance to chlorine-based oxidants. Therefore, operators have relatively few options regarding chemicals which can be safely used to disinfect or biocide cleaner of RO/NF systems and prevent bio-growth and biofouling. One option is the chemical, 2,2-Dibromo-3-nitrilopropionamide (DBNPA), which is a fast-acting, non-oxidizing biocide which is very effective at low concentrations in controlling the growth of aerobic bacteria, anaerobic bacteria, fungi and algae. 

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. It is degraded by reactions with water, nucleophiles, and UV light (rate is dependent on pH and temperature). The approximate half-life is 24 hr @ pH 7, 2 hr @ pH 8, 15 min @ pH 9. The vast majority of microorganisms that come into contact with it are killed within 5 to 10 minutes.


Mechanism of Action

DBNPA disrupts microbial metabolism, inhibiting key enzymes and cellular processes. It hydrolyzes rapidly under alkaline conditions, degrading into non-toxic byproducts such as dibromoacetonitrile and dibromoacetic acid.
