Product description

Reliable monitoring for the absence of free chlorine – with the DULCOZERO measuring system

Reliable monitoring for the absence of free chlorine is indispensable in many water treatment processes. During diaphragm processes, e.g. for desalination (reverse osmosis Reverse osmosis is a sub-sector within membrane filtration. It is the process with the highest ... more in the glossary), free chlorine often has to be used initially for disinfection, but then has to be eliminated again to protect the diaphragms. Even the lowest concentrations of free chlorine breaking through may irreversibly destroy the diaphragms and cause huge amounts of damage. Even after long periods when free chlorine is not present, the chlorine monitoring system DULCOZERO FCL reliably issues alarms to indicate a sudden chlorine breakthrough in < 3 min using an alarm threshold for free chlorine of 0.02 mg/l or more. The following contribute to high levels of process reliability: the innovative amperometric sensor, which is tolerant to the absence of free chlorine, an algorithm for smartly interpreting the sensor signal and logical analysis of the pH and ORP auxiliary measured variables The physical variables to be determined by measuring. more in the glossary. A convenient, fully integrated calibration When a metering pump has been installed, the capacity in litres per hour has to be determined under ... more in the glossary and monitoring system guarantees functionality, even during long periods when chlorine is not present.

Providing all the benefits of an amperometric chlorine sensor, DULCOZERO FCL can also be used in applications where the free chlorine is not metered continuously, e.g. in drinking water treatment (needs-based disinfection, emergency disinfection) or during the disinfection intervals, which are often used during the treatment of cooling water.

Your benefits

  • Excellent process reliability thanks to the rapid and reliable issuing of alarms in the event of chlorine breakthrough, after long periods when free chlorine is not present, at concentrations of > 0.02 ppm, in less than 3 min and with great accuracy
  • Reliable measurement and control mode without affecting the amperometric sensor even during long periods when chlorine is not present in applications with (discontinuous) disinfection processes
  • Low operating costs: within a calibration interval lasting several months, the sensor does not have to be activated by metering chemicals
  • The alarm system is protected by smart interpretation of the chlorine sensor signal (based on an algorithm) and logical linking with the pH and ORP auxiliary measured variables
  • Convenient, fully integrated calibration and monitoring system guarantees functionality, even during long periods when chlorine is not present. Menu-based calibration process via the DACb measuring device.
  • Amperometric measuring principle means no interference caused by turbidity or discolouration
