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 ), 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 . A convenient, fully integrated calibration 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.
