The need for effective and efficient wastewater treatment has become paramount. Bionic System Solutions (BSS), leveraging its collaboration with Vand Center Syd Denmark (VCS), has developed an innovative Soft-Sensor solution for optimizing chemical usage in phosphorus removal. This case study examines the implementation of BSS's Soft-Sensor solution at Otterup Wastewater Treatment Plant (WWTP) in Denmark, marking a significant milestone in sustainable water treatment.

The Challenge

As wastewater treatment plants face strict requirements for phosphate levels in treated water, they often resort to excessive chemical use to meet these standards. This approach leads to higher operational costs, increased CO2 emissions, and potential ecological damage. Otterup WWTP needed a cost-effective solution to optimize chemical dosage without compromising on treatment quality or investing in expensive new hardware.

Our Solution

The Soft-Sensor solution offers a flexible, accurate, and cost-effective approach to chemical dosage optimization. Key features include:

1. Purely digital solution utilizing existing data and infrastructure

2. Machine learning and mathematical models for precise predictions

3. Real-time adjustment of chemical dosing

4. Integration with existing WWTP systems

5. Low maintenance requirements and high reliability

Developed in collaboration with VCS, the Soft-Sensor employs cutting-edge data analysis to predict optimal ironsulphate dosage for phosphorous removal with remarkable precision.

Implementation at Otterup WWTP

The installation of the Soft-Sensor at Otterup WWTP represents a pioneering deployment of BSS's digital solution in a wastewater treatment facility. This implementation aims to:

1. Optimize chemical usage for phosphorous removal

2. Reduce operational costs and carbon footprint

3. Maintain compliance with strict phosphate level requirements

4. Offer a scalable solution adaptable to the plant's specific needs

Results and Future Prospects

The implementation of the Soft-Sensor at Otterup WWTP led to impressive results:

1. Over 20% reduction in chemical usage and associated costs

2. Significant decrease in the plant's carbon footprint

3. Maintained compliance with phosphate level requirements

4. No risk of low dosing, ensuring treatment quality

BSS sees this successful implementation as a model for future installations in other WWTPs, particularly smaller facilities facing resource constraints. The company is confident that the **Soft-Sensor's** versatility and effectiveness will make it an attractive option for wastewater treatment plants seeking to enhance operational efficiency and sustainability.

Conclusion

The deployment of the Soft-Sensor at Otterup WWTP demonstrates BSS's commitment to addressing environmental challenges with innovative technology. As sustainability demands in the water sector continue to grow, solutions like the Soft-Sensor will play a crucial role in optimizing wastewater treatment processes while reducing environmental impact and operational costs.
