Introduction

In the bustling operations of kraft paper mills, producing materials like cardboard often comes with a hidden challenge: odor control. This issue not only disrupts the environment but also strains relationships with local communities. For one kraft paper mill, the odor problem had become so severe that nearby villagers raised concerns, prompting the mill to seek a lasting solution.

Enter Venlar, a trusted name in wastewater and odor management. With innovative biotechnology solutions, we transformed the mill’s approach to odor control, creating a cleaner, more sustainable operation.

The Challenge: Addressing Odor in High-Temperature Environments

Upon visiting the facility, our team discovered key issues that contributed to the persistent odor problem:

  • Enclosed Aeration Tank: To contain odors, the mill had installed a canopy over the aeration tank. While this prevented gases from escaping, it led to an internal temperature spike, reaching an unbearable 55°C.
  • Heat Impact on Treatment: At such high temperatures, traditional bacteria-based microbial treatments were ineffective, as most microbes struggle to survive in extreme heat.
  • Budget Constraints: Installing a cooling tower to regulate the tank’s temperature was not feasible due to cost limitations.

The mill needed an urgent, cost-effective solution that could work within these constraints while addressing the odor problem.

Our Solution: Enzyme-Based Odor Control

Venlar’s team recognized the need for a non-traditional approach. Instead of relying on standard microbial treatments, we introduced an enzyme-based solution tailored to the mill’s high-temperature environment.

What Our Enzyme Treatment Achieved:

  • Odor Elimination:
    The enzymes broke down odor-causing compounds, neutralizing the smell that had been troubling nearby villagers.
  • Pollutant Oxidation:
    The treatment facilitated the breakdown of pollutants in the aeration tank, improving the overall quality of wastewater.
  • Immediate Results:
    Unlike microbial treatments, which require optimal conditions for growth, enzymes worked effectively and immediately, regardless of the high temperature.

Future Recommendations

While the enzyme treatment successfully resolved the immediate odor issue, we strongly recommended the installation of a cooling tower as a long-term solution. Regulating the aeration tank’s temperature would enable:

  • The use of cost-effective microbial treatments.
  • Improved breakdown of complex pollutants.
  • Enhanced overall efficiency of the treatment process.

Impact: Cleaner Operations, Happier Communities

With Venlar’s intervention, the kraft paper mill achieved:

  • Odor-free operations: Villagers no longer experienced unpleasant smells, restoring goodwill between the mill and the community.
  • Sustainability: The mill adopted a solution that addressed both operational challenges and environmental concerns.
  • Expert Guidance: By partnering with Venlar, the mill gained actionable insights for preventing similar issues in the future.

CONCLUSION

Odor control doesn’t have to be an insurmountable challenge. Venlar’s innovative approach demonstrates how biotechnology can adapt to even the most challenging conditions, offering tailored solutions that prioritize efficiency, sustainability, and community well-being.
