Highly purified water is used for the production of computer chips and photovoltaic wafers as well as for the production and cleaning of ingredients in the pharmaceutical industry. This water has a minimal content of residual ions, organic parts and or bacteria count. The first production step is softening by means of the ion exchanger. The subsequent reverse osmosis removes up to 99 % of the ions and up to 99.9 % of the organic components in the water. Depending on the requirements for purity another processing step is carried out via a second reverse osmosis or electrochemical deionisation. The processed water is fed to a storage tank. The individual tap points are supplied via a ring line with continuous flow. To maintain microbiological purity, germs which may be present are rendered inactive via short-wave UV radiation upstream of the ring line.

In this process different sensors are used: Flow sensors ensure compliance with the required flow speed. Pressure sensors monitor the differential pressure of filters. The position of pneumatic diaphragm valves is monitored via safe feedback systems. As the cleaning or disinfection of a reverse osmosis system is carried out with aggressive media such as tensides, citric acid or peracetic acid, the condition of the valve diaphragms must be monitored.

By combining several treatment units the controller can generate a high degree of automation by means of the hygienic sensors used. As from reverse osmosis devices with calibration certificates of the manufacturer are standard. In this case for pressure and conductivity. An inspection certificate 3.1 is also required. Many different sensors can be obtained from one supplier. These sensors are normally fitted with a human machine interface and can be preset to the application. This is increasingly done via IO-Link.
