Spectrum™ XD3899 microbiocide
Spectrum XD3899 is a unique, patented microbiocide that effectively controls microorganisms in alkaline papermaking systems without the adverse side effects associated with strong oxidizing biocides. The microbiocide drastically reduces microbiological activity throughout the entire papermaking process, providing a truly clean machine. From the machine stock system to the headbox and throughout the white water system, the microbiocide controls all types of microorganisms, including filamentous bacteria, unicellular bacteria, anaerobic bacteria, yeast and mold.
The Spectrum XD3899 microbiocide, which can be described as a mild oxidizer, has proven to be more effective than strong oxidizing biocides and organic biocides. Additionally, the technology has been shown to provide benefits not typical of traditional programs, including improved drainage, enhanced felt performance and improved wet end chemistry efficiency. Notably, more than 700 paper machines around the world use Spectrum XD3899, making it the most widely used biocide in the paper industry.

Automated Dosing and Control
The Spectrum XD3899 microbiocide is produced onsite using proprietary dosing equipment (see Figure 1) that can be accessed and controlled remotely. The dosing system blends an ammonium bromide solution with sodium hypochlorite and mill fresh water under required reaction conditions to ensure 100% conversion of the biocide components. By strictly controlling the reaction, the system ensures that only the intended biocide is produced.

The Spectrum XD3899 microbiocide is generated only when needed and is fed intermittently, allowing for reduced biocide usage. The dosing system also automatically adjusts biocide production to correct for any variances in biocide quality.
