Ensuring the safety and quality of drinking water is a complex task that requires precise control and monitoring. In a drinking water pumping station in eastern Spain, the challenge of maintaining this precision led to significant operational issues with their existing system. Grundfos' innovative DID (Digital Instrumentation Dosing) system met the plant's need for a reliable, low-maintenance solution. Here's how this transformation unfolded.
The Old System: Challenges and Limitations
Previously, the station used a peristaltic pump system to manage water treatment chemicals. This setup involved separate plastic containers for chemicals susceptible to heat, compromising measurement reliability. Additionally, the chemical inlet tubes wore out quickly, leading to frequent replacements. The process required sequential and very frequent sampling, adding to the complexity and maintenance burden.
The system was far from optimal, resulting in inefficiencies and higher maintenance needs. Recognizing these issues, the plant manager sought a more reliable and efficient solution.
Enter Grundfos Digital Instrumentation Dosing: A Tailored Solution
Grundfos stepped in with a proposed solution that promised to address their challenges. Grundfos recommended the digital instrumentation dosing system for continuous measurement and control, aiming to resolve the issues of the previous setup while integrating seamlessly with the existing data recording systems of the plant.
The Grundfos digital dosing system offers several advantages:
- Continuous Measurement: Unlike the old system, which measured free chlorine intermittently, the DID system provides uninterrupted monitoring, ensuring consistent water quality.
- No Need for pH Correction: The digital dosing pump eliminates the need for additional pH correction chemicals, simplifying the process.
- Minimal Maintenance: The digital instrumentation dosing system is practically maintenance-free, reducing the need for frequent upkeep and lowering operational costs.
Implementation and Results
After a thorough assessment and discussion with the plant’s maintenance manager, Grundfos implemented the DID system. The transition was smooth, with the system integrating easily with the existing control and monitoring infrastructure.
The results were impressive. The DID technology allowed for accurate and continuous measurement of free chlorine without the issues of pH correction or chemical handling. The maintenance manager reported:
- Low Maintenance Needs: The digital dosing pump system requires only occasional changes of small quantities of electrolyte, approximately every six months. Calibration is infrequent and usually unnecessary.
- Seamless Integration: The analogue outputs of the DID system ensured full compatibility with the plant’s data logging and real-time monitoring systems.
The Impact: Efficiency and Accuracy
Three years after the installation, the Grundfos DID system has met and exceeded the plant’s expectations. The system has proven to be a reliable and low-maintenance solution, significantly reducing operational costs while maintaining high measurement accuracy.
The feedback from the pumping station highlights the benefits of the digital instrumentation dosing system:
- Flawless Operation: The equipment's reliability and ease of maintenance have been well-received.
- Cost Savings: Reduced maintenance requirements have led to lower overall costs.
- Accurate Monitoring: Continuous measurement ensures better control over water quality.
In summary, the Grundfos dosing pump has transformed this particular Spanish drinking water pumping station by providing a more efficient, cost-effective, and accurate solution for water treatment. This case illustrates how advanced technology can resolve issues in long-run and improve operational efficiency in critical infrastructure.
