CAS No.: 52-51-7

EINECS No.: 200-143-0

BRONOPOL 99 is broad-spectrum bactericide used to control microbial growth and its associated problems in industrial process systems such as cooling water, oil production and transport, pulp and paper production. When it is used in industrial process or as a preservative in water- containing systems, it provides the following benefits:

1.Efficacy against Pseudomonas.

2.Control of slime-forming bacteria.

3.Control of anaerobic organisms responsible for microbial-induced corrosion.

4.Application approvals in numerous international markets.

Pseudomonas fluorescens	25

Applications/Directions for Use

It may be used in the following end-use applications.

Pulp and Paper

It may be used for the control of slime- forming bacteria in paper mill process water and bulk pulp. It can be added into the hydropulper, machine chest or stock check. The correct dose of active ingredient for these applications is 10-250 ppm BRONOPOL in paper mill process water and 50-250 ppm BRONOPOL in bulk pulp.

Water Treatment

It may be used to control slime-forming bacteria in recirculating water cooling towers, evaporative condensers, industrial process water, and air scrubber, air conditioner and humidifier systems. BRONOPOL may be dosed directly into the sump or basin at any point where there is adequate agitation to ensure dissolution. The correct dose range of active ingredient is 25-100 ppm BRONOPOL.

Oil Production

It may be used to control aerobic and anaerobic bacteria, especially sulfate-reducing bacteria, in oil and gas-related production Bronpol may be dosed at any convenient point in the process. The dose rate for oil flooding/injection waters, enhanced oil recovery fluids, produced water, drilling fluids, fracturing fluids and workover and completion fluids is 50-100 ppm BRONOPOL. The dose rate of active ingredient for well squeeze fluids and fracturing fluids is 25-200 ppm.

Oil and Gas Transportation and Storage

It may be used to control aerobic and anaerobic bacteria that contribute to corrosion in pipeline maintenance and water bottoms in oil or transportation tanks. The dose range for water bottom in oil or transportation tanks is 50-100 ppm in the aqueous phase. For pipeline maintenance the dose range is 25-200 ppm.

Packing: 25Kg Fiber drum.
