Industrial Uses

1. Water Treatment 

  • Disinfectant for Cooling Towers: DBDH is used to release active bromine slowly into industrial cooling towers to control microbial growth and prevent biofilm.
  • Swimming Pool and Spa Sanitizer: DBDH is used in tablet or granular form as a source of bromine to maintain hygiene by neutralizing pathogens in recreational water.
  • Oxidizing Agent for Wastewater Treatment: DBDH is applied in industrial effluent streams to oxidize organic compounds and reduce microbial contamination.
  • Potable Water Reservoir Protection (non-contact systems): DBDH-treated water is used in adjacent processes to prevent microbial growth without direct human consumption.

2. Energy

  • Biocide in Injection Water Systems: DBDH is added to water used for enhanced oil recovery to eliminate microbial contamination and protect infrastructure from souring and corrosion.
  • Microbial Inhibitor in Drilling and Fracturing Fluids: DBDH is used to prevent bacterial growth in hydraulic fracturing fluids that could clog pores or react with formation materials.
  • Preservation of Storage Tanks: DBDH solutions are dosed in water storage tanks used in oilfields to maintain microbiological integrity during long-term storage.

3. Pulp & Paper Solutions

  • Slimicide in White Water Loops: DBDH is used to prevent the formation of microbial slime in water loops which are reused in paper manufacturing.
  • Process Water Sterilization: Added to process water to prevent fouling and reduce microbial load that can impact paper quality and machine efficiency.

4. Fabric Solutions

  • Biocontrol in Wet Processing Units: DBDH is dosed into dyeing, bleaching, and washing units to reduce bacterial contamination during textile treatment stages.
  • Cooling System Disinfection: Textile processing plants use DBDH in cooling circuits to inhibit microbial buildup that could interfere with temperature regulation.

5. Performance Chemicals

  • Controlled Halogenating Agent: DBDH is used in organic chemistry to introduce bromine atoms in a controlled manner during the synthesis of intermediates for pharmaceuticals, agrochemicals, and dyes.
  • Stabilizer in Halogen-Containing Products: Acts as a halogen source in formulations where a stable release of bromine is needed over time.

6. Food & Healthcare Ingredients

  • Sanitization of Non-contact Process Water: DBDH is used to treat process water that comes into indirect contact with equipment or surfaces in food plants to maintain sanitation.
  • Odor Control in Waste Streams: DBDH helps manage odor-causing microbes in food processing wastewater before discharge or reuse.
