Efficient and sustainable water treatment is critical for maintaining smooth operations in paper and board manufacturing. A leading paper manufacturer faced persistent issues with high microbial activity and slime growth, which directly impacted product quality and the working environment. The solution came in the form of Bansan SCD, an innovative biocide known for its stable and effective chlorine dioxide technology.
Problem
The paper manufacturer encountered the following operational challenges in their production process:
- Excessive biocide consumption to control microbial growth
- Frequent defects such as holes in paper, compromising product quality
- Increased potential for microbial growth due to water system demands
- Noticeable biocide odor impacting the production environment due to high dosage levels
These issues not only led to inefficiencies but also increased overall operational costs.
Solution
To address these challenges, the paper manufacturer adopted Bansan SCD as a comprehensive slime control solution. Key steps included:
- Integration of Bansan SCD as a single-component system for controlling slime formation
- Application across short and long circulation systems to ensure broad-spectrum microbial control
- Optimization of free chlorine levels to maintain system cleanliness while controlling costs
- Complete replacement of DBNPA, resulting in a streamlined and effective treatment process
The implementation of Bansan SCD was seamless, utilizing existing dosing infrastructure with minor adjustments.
Results
The adoption of Bansan SCD delivered measurable improvements:
- Reduction in biocide dosing requirements by 67–74%, minimizing chemical consumption costs
- Achieved stable chlorine levels within the system, effectively inhibiting microbial regrowth
- Eliminated biocide odors, ensuring a cleaner and more comfortable production environment
- Significant improvement in paper quality, reducing defects such as holes caused by microbial activity
- Enhanced operational efficiency, lowering microbiological contamination to target levels
Additionally, the customer was able to cut down biocide costs by 35% on a yearly basis, leading to substantial financial savings. This reduction highlights the effectiveness of optimized biocide dosing and improved system performance
Benefits
Bansan SCD brought significant advantages to the manufacturer:
- Cost Efficiency: Reduced biocide consumption led to annual cost savings
- Optimized Performance: Improved microbiological control, preventing contamination risks and maintaining system stability
