description and use

Spectrus OX909 is a specially formulated stabilized bromine based biocide.

Spectrus OX909 controls bacterial, fungal, and algal slimes in recirculating cooling water in commercial or industrial cooling towers.

Control of microbiological populations is essential to prevent biofouling. Biofouling of heat exchange systems and tower fill reduces heat transfer efficiency leading to higher energy costs. Biofouling can also damage equipment through microbiologically influenced corrosion (MIC) and force unscheduled shutdowns, or extended turnarounds leading to lost production.

Biofouling in cooling systems can provide an ideal environment for proliferation of Legionella bacteria, the cause of Legionnaires’ disease. Halogens have been recommended by various agencies (CTI, ASH- RAE, CDC, etc.) as an integral part of Legionella Risk Reduction programs. Spectrus OX909 provides a significant halogen residual that can be measured with a standard total chlorine test. The active in Spectrus OX909 has proven highly effective against Legionella bacteria in laboratory testing. Note however that chemical treatment alone will not be effective in reducing health hazards associated with Legionella bacteria.

System design and location, maintenance practices and employee awareness are critical elements of a successful risk reduction program.

Spectrus OX909 biocide is EPA-registered for use as a disinfectant, fungicide, algaecide and/or slimicide for wastewater, commercial and industrial recirculating cooling water systems, industrial once-through cooling water systems and pulp and paper mills. It also controls bacterial, fungal, and algal slime in decorative fountains, air washers and food, beverage, and industrial process pasteurizers.

For a complete listing of EPA-approved end-uses, see the Spectrus OX909 product label.

treatment and feeding requirements

Proper treatment levels for Spectrus OX909 depend on many factors, such system cleanliness, types of microbes, nutrient concentrations, temperature, pH, retention time, and other system operating characteristics. Consult the product label for general dos age guidelines. Microbiological monitoring is recommended to evaluate product requirements.

Consult your VEOLIA representative for technical advice on your specific application. Conventional feeding equipment like a diaphragm pump or peristaltic pump is recommended. Current bleach systems can be used if they are thoroughly cleaned and free of contaminants.

Tanks, pumps, valves and associated piping should be made of titanium, Hastelloy C-276, Monel 400, vinyl tubing, polyethylene, polypropylene, PVC, Viton, Teflon, Tygon tubing, chlorobutyl rubber and Hypalon. (Hastelloy is registered trademark of Haynes International.
