Abstract
Historically non oxidizing biocides have been used to control microbiological growth and its adverse effects in paper manufacture. This paper explains the chemistry and presents successful case histories describing the use of Bromo-Chloro-5,5-Dimethylhydantoin (BCDMH), a solid bromine releasing oxidizing biocide, to control slime build-up in paper manufacture process water. BCDMH offers the paper manufacturer a unique solution to microbiological problems by overcoming the disadvantages of traditional non oxidizing biocides.
Conclusion
This paper has given the benefits of BCDMH as a biocide of choice for controlling biological problems in today's paper manufacturing process. Laboratory and field trials, along with commercial use, have shown BCDMH to be a proven chemistry with proven performance for wide applications in paper mill water systems.
BCDMH offers many advantages over the traditional non-oxidizing biocides. These include favorable economics, rapid activity, easy field measurements, and rapid degradation to inert by products.
More studies are in progress to document the technical details of BCDMH. This paper was presented to create the awareness of the potential of BCDMH chemistry in solving the microbiological problems worker exposure and environmental issues experienced in paper manufacture.
