SpectrusTM OX1201 (40% sodium bromine by
weight) is a safe, easy-to-use source of bromine in liquid form. The bromine in this product is present as inactive bromide ion (31% Br- ). It must be oxidized to Br+ in order to exert a toxic effect on microorganisms. Conversion of Br- to Br+ is usually achieved by co-feeding Spectrus OX1201 with chlorine (either gas or liquid bleach). In water, oxidation of Br- to Br+ results in the formation of hypobromous acid (HOBr), which is superior to hypochlorous acid (HOCl) for control of microbes in ammonia contaminated, high pH, and/or once- through waters.
Process leaks frequently require high rates of chlorination, from gas or liquid bleach, to maintain microbiological control. These high rates impose a penalty in the form of increased corrosion, however. Experience has shown “topping off” chlorine programs with Spectrus OX1201 can reduce corrosion rates and enhance microbiological control.
Spectrus OX1201 is approved by the EPA for use in once-through and recirculating cooling systems, influent and wastewater systems, as well as waterbased scrubbers, brewery pasteurizers, and industrial air washers equipped with mist eliminators.
Control of microbiological populations in industrial water systems is essential to prevent biofouling. In cooling systems, biofouling of heat exchange equipment and tower fill reduces heat transfer efficiency and can force unscheduled shutdowns and extended turnarounds, leading to lost production. Biofouling can also damage equipment through microbiologically influenced corrosion (MIC). As a result of these effects, biofouling must be prevented in order for operating units to achieve profitability goals.
Treatment and Feeding Requirements
Activate bromide and generate HOBr by co-feeding Spectrus OX1201 with a source of chlorine. The ratio of chlorine to Spectrus OX1201 can be adjusted to produce an all HOBr stream or a mix of HOBr and HOCl. For example, to generate 100% HOBr, feed 3.6 pounds (1.6 kg) of Spectrus OX1201 per 1 pound (0.45 kg) of chlorine gas. To generate a 50:50 mix of HOBr and HOCl, feed 1.8 pounds (0.82 kg) of Spectrus OX1201 per 1 pound (0.45 kg) of chlorine gas.
To ensure efficient bromide activation, mix Spectrus OX1201 with bleach or gas chlorinator discharge solution prior to application to the tower basin or recirculating cooling water lines. Use an in-line static mixer to ensure adequate contact. Consult your Veolia representative for further information on feed system design.
In some systems, conversion from an all-chlorine program to a chlorine/bromide program will allow a reduction in daily chlorine usage. A 50% reduction in chlorine consumption is not unusual when Spectrus

OX1201 is applied at 1.8 pounds (0.82 kg) per 1 pound (0.45 kg) of chlorine. Further reductions in chlorine usage may be possible. Your Veolia representative can assist in optimizing the chlorine/Spectrus OX1201 program.
Correct treatment levels and frequency of Spectrus OX1201 addition depend on many factors. These include, but are not limited to, system cleanliness, types of microbes, nutrient concentrations, temperature, pH, retention time, and other system operating characteristics. Consult the product label for general dosage guidelines. Microbiological monitoring is recommended to evaluate product requirements. Consult your Veolia representative for technical advice on your specific application.
In all cases, this product must be applied in accordance with use instructions on the Spectrus OX1201 label.
