DESCRIPTION AND USE

Spectrus NX1104 is EPA approved for control of bacteria, algae and fungi in a variety of industrial, water-based systems. Spectrus NX1104 consists of a patented blend of 5% dodecylguanidine hydrochloride (DGH) and 8% quaternary ammonium hydrochloride (Quat).

Spectrus NX1104 is approved for use in open recirculating cooling systems, heat exchange systems and evaporative condensers. This product is also approved for use in once-through cooling water systems.

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. Equipment can also be damaged as a result of microbiologically influenced corrosion (MIC) associated with biofouling. Consequently, biofouling must be prevented in order for operating units to avoid such events and achieve profitability goals.

Spectrus NX1104 is highly effective against Sulfate Reducing bacteria which are frequently associated with MIC (see Chart). Compared to single active biocide products, the combination of active ingredients (DGH and Quat) in Spectrus NX1104 work together to provide faster microbial control at lower dosages.

The blend of actives in Spectrus NX1104 also limits development of resistant microbial populations and effectiveness. Spectrus NX1104 demonstrates excellent activity against algae even under alkaline pH conditions and is fully compatible with chlorine and bromine disinfectants. The surface active nature of Spectrus NX1104 aids in control and removal of biofilms and enhances the performance of oxidizerbased disinfection programs.

In addition to cooling systems, Spectrus NX1104 can be used to control microbes in auxiliary water systems such as fire protection systems, and waste water and waste material disposal systems such as storage tanks, ponds and disposal wells. Spectrus NX1104 can also be used to control microbes in influent water systems, pasteurizers, and water-based scrubbers. See the Spectrus NX1104 product label for a complete listing of approved end uses.

TREATMENT AND FEEDING REQUIREMENTS 

Correct treatment levels and frequency of Spectrus NX1104 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 GE Betz representative for technical advice on your specific application.

In all cases, this product must be applied in accordance with use instructions on the Spectrus NX1104 label.
