RO Biocide DBN 20

Product Description

RO Biocide DBN 20 is a highly effective, environmentally friendly biocide. It provides a quick kill while also quickly degrading in water. RO Biocide DBN 20 is a concentrated, fast-acting, non-oxidizing liquid biocide for intermittent use that provides instant antimicrobial activity. It is based on a 20% solution of the active ingredient dibromo nitrilopropionamide (DBNPA) along with other ingrident. It degrades rapidly and naturally, making it a cost-effective method of eliminating contamination in compliance with strict discharge regulations.

Application :

RO Biocide DBN 20  is used in RO applications as a biocide for intermittent use or as a membrane cleaner. For potable applications, refer to local regulations.

Compatibility with other water treatment chemicals and water conditions:RO Biocide DBN 20 is compatible with other treatment chemicals with the exception of mercaptobenzothiazole. It also is not compatible with ammonia or hydrogen sulfide-containing water. DBNPA maintains reliable control in systems running at acidic, neutral, or alkaline pH.

Dose :

Biocide for Intermittent Use
Used as an on-line biocide for intermittent use, RO Biocid DBN 20  acts like a “shock treatment” to control fouling. The dose level and frequency should be optimized according to the bacteriological challenges present in the feedwater. A typical dose is 25-50 mg/l for one hour per week.

RO Membrane Cleaner
RO Biocid DBN 20   is normally applied as the first stage of cleaning using solutions of 50-200 mg/l depending on the degree of fouling. The solution is circulated through the membranes for 1-3 hours. Because RO Biocid DBN 20  is a fast-acting biocide, it should be added in batches of 50 mg/l four times during the circulation period.

Technical Property

Future & Benefit  : 

• Instantaneous antimicrobial activity as a non-oxidizing slimicide and bactericide.
• Kills bacteria, fungi and algae.
• Degrades rapidly and naturally to comply with strict environmental discharge regulations.
• Compatible with polyamide and cellulose acetate membranes.
• Can be used with other RXSOL cleaners.
