Installation of the compact Online Water Analysis System was a simple process.


lag meant that chlorine would have penetrated to the RO membrane. If an electrodeionisation (EDI) system were in use instead of an RO membrane, even trace chlorine down to 0.05ppm could cause damage, emphasising the need for rapid detection.


RAPID DETECTION AND PRECISE ANALYSIS

If chlorine is detected by the Type 8906 Online Water Analysis System, it can issue real time alerts, and visual alarms can also be set up to initiate an immediate response. The system also includes a 7-inch touchscreen to display live information, and records from the data logger can also be reviewed retrospectively for historical analysis. As a result of the study, Veolia Water Technologies Ireland now has the potential to prevent virtually any chlorine traces entering the RO system, helping to achieve and maintain zero-chlorine conditions entering its customers’ RO systems. While establishing a much more robust system to protect the RO membranes, the approach is also saving significant cost and time compared to using traditional chlorine detection solutions. “Bürkert recognised a real operational pain point for Veolia and translated it into a practical, technically sound monitoring solution that protects our RO membrane systems,” says Kieran Lyons, project director Ireland, Veolia Water Technologies.
