General
BRONOPOL 99% Water Treatment Microbiocide preservative 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.
Directions for Use: BRONOPOL Water Treatment Microbiocide preservative may be used in the following end-use applications.
1) Pulp and Paper
BRONOPOL Water Treatment Microbiocide 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.
2) Water Treatment
BRONOPOL Water Treatment Microbiocide 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.
3) Oil Production
BRONOPOL Water Treatment Microbiocide 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.
4) Oil and Gas Transportation and Storage
BRONOPOL Water Treatment Microbiocide 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.
Advantage:
(1) Highly efficient, with broad-spectrum antibacterial activity, can inhibit the growth of most bacteria at25ppm concentration, and better for Gram-negative bacteria and various Pseudomonas species;
(2) Good compatibility. Nutrients such as protein and various cationic, anionic, nonionic surfactants will not affect its antibacterial effect;
(3) A suitable pH range. It is effective in the range of pH 4～9, that is, in the environment of weak acidity, neutrality and partial alkali, it can maintain strong antibacterial effect after adding;
(4) Low dosage and low price. In cosmetics, the dosage is generally 0.01~0.05%, which is one tenth of the common preservatives of parabens, and the cost of use is more than half of that of parabens;
(5) Good water solubility and easy to use. It is easily soluble in water and has a solubility of 25g in water at 25 ° C. It is extremely convenient to use.
Application:
Biocide, mainly used in industrial circulating water, paper pulp, paint, plastics, cosmetics, wood, cooling water circulation system, as well as sterilization, mildew, anti-corrosion and algae killing for industrial purposes.
