Eighteen Kuntze Krypton® Multi

Noréade is a public establishment for intermunicipal cooperation located in the north of France. The main areas of service are water distribution and sanitation in a territory of approximately 1 million inhabitants. 99% of the water distributed by Noréade comes from groundwater aquifers. To prevent bacterial growth in the water, it is crucial to keep a level of 0.3 and 0.5 ppm for free chlorine.

As the previous system required reagent usage, the sample water could not be discharged into the aquifier, but had to be collected and disposed as chemical waste. The customer required a new technology that provides reliable measurements, reduces maintenance and prevents contamination of the sample water.

The French Kuntze partner “C2Plus” installed 18 Krypton® Multi water monitoring systems for the measurement and control of free chlorine in the water towers and tanks at Noréade. Through its Stabiflow® unit the Krypton® Multi keeps the water flow constant automatically and without manual intervention.

Due to the use of highly accurate sensors instead of reagents, the water quality is also much higher because the bare Zirkon® DIS sensors react to changes in the water so that the correct amount of disinfectant can be applied. In addition, 18 MODBUS Addons were set up functioning as Remote Terminal Units for data exchange.

The confidence in a more accurate, stable and automated system in combination with a remote communication function, allows the public authority to ensure high water quality while significantly reducing the manual workload on its employees.

Since 1950, the mission of Noréade is supplying the territory of North France with high quality drinking water. Approximately 1 million inhabitants live in the territory split into 750 municipalities. Noréade is an employer to nearly 600 employees.
