STABROM® 909 Biocide
STABROM 909 Biocide is a single-feed, stabilized bromine-based biocide for industrial water treatment applications. Product halogen activity is approximately 15% as Br, equivalent to approximately 7% as Cl . 2 2
Applications
STABROM 909 Biocide is EPA-registered for use as a fungicide, algicide, slimicide and microbiocide in recirculating cooling and process water systems, heat transfer systems (such as hydrostatic sterilizers and retorts, pasteurizers and warmers, and batch and continuous cookers), air washers and industrial scrubbing systems, containerized ponds and decorative fountains, industrial once-through cooling water systems, pulp and paper mills and wastewater systems. It is also EPA-registered to control biofilm deposits from pumps, pipework, heat exchangers and filters associated with industrial water treatment systems. Please contact Albemarle Corporation if you have any questions regarding STABROM 909 Biocide applications.

- Incompatible
- In its neat form, this product is not compatible with Buna-N rubber, neoprene, silicone rubber,
- Plasite® 4300 and 3070, nylon, aluminum, brass, carbon steel, copper, stainless steel and other common metals. This product is strongly basic and an oxidizing agent. Contact with organic materials such as alcohols and aldehydes, strong reducing agents, strong oxidizers, acids, and ammonia-containing products should be avoided. Use of incompatible materials can promote the exothermic decomposition of the product. In extreme cases, this could result in vigorous gas formation and over-pressurization of storage containers.
Handling Instructions
For specific safety, handling and toxicity information please refer to the current material safety data sheet.
Storage Instructions
STABROM 909 Biocide should be stored away from incompatible materials. To maximize product shelf life, the product should be stored in a cool, dry, well-ventilated area in opaque containers, to minimize exposure to light and especially sunlight. As the product ages, activity is gradually lost and nitrogen pressure can build up in the headspace; therefore, the product should be stored in vented containers. Avoid freezing, excessive heat or exposure to light, especially direct sunlight. Heating of the product above what is needed for freeze protection should be avoided as it can accelerate decomposition. Temperature monitoring is recommended. Precautions should be taken to ensure that the average temperature of the product is maintained below 110 °F (~43 °C). This product retains 95% of its initial activity for at least one year when stored properly at ambient temperatures (80 °F / ~27 °C), and protected from light.
