Abstract
While paper-making technology has been made progress, slime treatment issue also has been getting more important. Neutralization of pH, reduction of fresh water and increase of using recycled furnish cause in continuously serious slime problem and require more effective slime control technique. From the view of slime control history from 1970, the technology has been developed roughly through three generations.
First generation is “organic biocide” : try to prevent slime deposit by combination of organic biocides.
Second generation is “inorganic biocide & cleanliness treatment” : Development Fuzzicide® technology mostly solved any slime problems. Furthermore, cleanliness treatment in whole the process achieved completely slime defects prevention. Third generation is “water quality stabilization” : We found microbial activity changes water qualities and influences on paper-making operation. Thus we have been developing S. sensing® system, that has three functions of monitoring, feeding control and analysis and then try to achieve operation stabilization and cost saving simultaneously by stabilizing water quality.
