The water is treated in various stages, such as oxidation, disinfection, and softening. To safeguard your plant’s operation, Phoenix Contact provides products and solutions that meet the high requirements on water treatment. With redundant systems, the sensitive processes in your plant are reliably controlled and monitored – from the ﬁ eld all the way to the control level. Your advantages  Always keep an eye on your system with on-site visualization with integrated remote diagnostics  Reliable signal acquisition from plant parts, even in the event of a power failure  Uninterrupted operation thanks to a redundancy concept with high-performance safety controllers 24 PHOENIX CONTACT

Integrated remote diagnostics in the disinfection process Modular, easy marshalling in the ozone plant Redundant controller in ﬁ ltration stage 2 For the precise control of the treatment plant with the use of, say, chlorine dioxide, the measured values for ﬂ ow rate and residual chlorine are used. The combination of modular control technology with integrated eHMI including ready-programmed visualization blocks makes precise control with on-site operation using a web-based touch display possible. To control the concentration of ozone gas in an oxidation process, a secure connection is established between the ﬁ eld devices and the controller. Analog and digital inputs and outputs make it possible to easily handle the signals at this level. This information is transmitted to the control system through standard communication protocols such as Modbus, PROFIBUS, and PROFINET. Diff erent types of pollution require diff erent treatment processes. Complete redundancy concepts with the high-performance RFC 4072S safety controller contribute to uninterrupted operation. It is also possible to use it in applications with the highest safety requirements in accordance with SIL 3 or PLe, respectively. Consistent redundancy, from the ﬁ eld level to the control room Failsafe performance is crucial, in particular in the various stages of water treatment. To guarantee maximum availability, it is vital to establish a redundant system. Phoenix Contact provides reliable concepts and redundant components for the automation of your plant. From the easy integration of ﬁ eld devices, through the control and network level, all the way to the control system, a broad product and solution range is available. You can therefore ensure the uninterrupted and continuous operation of your plant.

Solutions for the drinking water supply Water transport and distribution To make the drinking water available at many points, an extensive supply network is often required. Continuous access to all systems for control and monitoring purposes is absolutely essential in this. With this in mind, Phoenix Contact provides turnkey solutions, from remote monitoring, to leakage management systems, right through to minimizing water losses. A cloud connection of the individual controllers allows access to all relevant system data through a secure connection. Your advantages  Cloud connection made possible easily with the use of PLCnext Technology  Minimization of water losses with leakage management system  Data transparency: from the control room or mobile device 26 PHOENIX CONTACT

Device management The use of PLCnext Control devices allows communication to a cloud with little eff ort. Data from the connected devices at each well can be called up over a direct connection. Information such as operating hours, utilization, and power consumption is transmitted to any cloud via MQTT, for example. Beneﬁ t from maximum availability, because you can access your data anytime, anywhere. This transparency makes it possible to establish immediate measures or long-term steps, such as maintenance management. Well control through the cloud is also possible, and can be established as a redundant system. Pressure regulation to reduce water losses The quantity of drinking water required from the network varies during the day, meaning that the ﬂ ow rate and pipeline pressure are of great importance when considering leakage losses. Together with partners, Phoenix Contact has developed a solution for minimizing losses in the pipeline. The solution is based on pressure management that does not depend on what is removed from the system. Access to your data anywhere and at any time Solutions for the water distribution network In a water distribution network, it is essential that remote stations are continuously monitored and controlled. Phoenix Contact off ers special solutions based on modular control technology for leakage and pipeline management. In addition to data transmission, various media such as SHDSL, wireless, and mobile technology are used. The solutions can be modularly extended and, thanks to parameterization instead of programming, can be easily put into operation.
