Q&A: Clean and safe water with Endress+Hauser’s disinfection sensors

In today’s world, ensuring clean and safe water is more critical than ever. This Q&A with Endress+Hauser’s Liquid Analysis Product Marketing Manager, Thomas Chirdo, explores the significance of disinfection processes and how Endress+Hauser’s liquid analysis sensors are enhancing water safety across various applications.

What is the significance of disinfection processes in light of current challenges?

Disinfection processes are critical in addressing pressing challenges such as climate change, water scarcity and population growth. By ensuring a clean water supply, disinfection processes safeguard public health and environmental well-being.

How do Endress+Hauser disinfection sensors differ from the commonly used DPD method?

Unlike the widely used DPD method, Endress+Hauser disinfection sensors operate based on the amperometric principle. This allows them to provide continuous and instantaneous measured values, enabling real-time monitoring and precise dosing of disinfectants while still meeting the EPA approval method for calibration.

Which disinfectants can Endress+Hauser sensors measure?

Endress+Hauser sensors are versatile and can measure various disinfectants, including chlorine dioxide, free chlorine, total chlorine, free bromine and dissolved ozone. Their flexibility makes them suitable for applications in drinking water, wastewater, pharmaceutical, sewage treatment plants, swimming pools, food production and other industrial processes.

Why are Endress+Hauser chlorine sensors particularly valuable?

Endress+Hauser chlorine sensors remain alert even during periods when no chlorine is present. Unlike some sensors that “fall asleep” or depolarize, these sensors continue to function reliably, instantly measuring chlorine levels when the disinfectant is reintroduced. This responsiveness ensures accurate and timely data for effective disinfection.

What technology enables easy replacement of Memosens sensors in the field?

Inductive Memosens technology revolutionizes liquid analysis by directly allowing quick and straightforward sensor replacement in the field. Operators can swap out sensors without extensive downtime or complex recalibration procedures with pre-calibrated sensors and a plug-in connection.

What additional functionality does Memosens 2.0 technology offer?

Memosens 2.0 enhances data capabilities by storing significantly more information. This expanded storage enables improved trend identification, predictive maintenance and Industrial Internet of Things (IIoT) services. Operators can optimize maintenance intervals based on data such as uptime, calibration history and load matrices.

How does the optimized polarization time benefit disinfection sensors?

The optimized polarization time ensures that Endress+Hauser disinfection sensors reach stable display values faster after commissioning. With the new Memosens 2.0 disinfection sensors, the required polarization time has been cut in half.

How are Endress+Hauser disinfection sensors low-maintenance?

These sensors feature robust components, including a dense, stain-resistant convex membrane and an improved electrolyte. Their durability minimizes maintenance requirements, contributing to cost savings and reliable long-term performance.

Where are disinfection applications relevant beyond waterworks and sewage treatment plants?

Disinfection is essential in various contexts beyond water treatment facilities. It is crucial in food production, swimming pools, pharmaceutical applications and numerous industrial processes that impact our daily lives.

What role do Memosens sensors play in safeguarding the clean water supply?

Memosens sensors provide continuous, reliable measurement data, optimize dosing and enhance overall disinfection processes. They contribute significantly to public health and environmental sustainability by ensuring water quality.
