Biosperse™ XD3899 microbiocide
Biosperse XD3899 is a unique, patented microbiocide that effectively controls biofilm formation in recirculating cooling water and chill water systems without the adverse side effects associated with strong oxidizing biocides. The microbiocide, which can be described as a mild oxidizer, drastically reduces microbiological activity in wet processes, providing a truly clean system. From cooling towers to heat exchangers and throughout process equipment, the microbiocide controls a broad spectrum of microorganisms that cause fouling, promote corrosion and adversely affect system performance.
The Biosperse XD3899 microbiocide specifically reacts with reductive compounds within microorganisms, rendering them unable to produce energy. Without their ability to produce energy, the microorganisms die before they have an opportunity to attach to process and cooling water surfaces. By hindering bacterial attachment, the subsequent formation of biofilm is prevented.
Notably, more than 700 paper machines around the world use the XD3899 microbiocide, making it the most widely used biocide in the paper industry.

Automated Dosing and Control
The Biosperse XD3899 microbiocide is produced onsite using patented dosing equipment and a proprietary monitoring and control system. The dosing equipment blends an ammonium bromide solution with sodium hypochlorite and fresh water under required reaction conditions to ensure 100 percent conversion of the microbiocide components. The dosing equipment also automatically adjusts microbiocide production to correct for any variances in product quality.
Key features of the dosing equipment and the monitoring and control system include closed-loop control (feed-back and feed-forward), remote monitoring and control, proportional dosing, automatic water flush of lines, multiple feed point interlocks, and notification of feed problems.
