Context

For the past 25 years, the city of Öhringen has continuously invested in modern water treatment facilities to guarantee a reliable and clean supply of water for its population of some 22,000.

However the Öhringen Waterworks was only able to measure overall turbidity, pH value, residual ozone and chlorine dioxide content at the inlet and outlet of the waterworks and all data was transferred using analogue signals – which meant there was extensive potential for optimising the plant.

Requirement

There was a need for a modern water analysis system which could reliably evaluate water qualities from various sources, initiate control and regulation tasks, introduce early warning and alarm systems and monitor the condition of the treatment technology.

Products used

Burkert's Online Analysis System Type 8905 was selected for water analysis as it could display reliable and continuous information about all key drinking water parameters at a glance. For the waterworks supervisor, the status of the water quality and technology would be visible at all times via a display – with very low consumption.

Outcome

In the Öhringen Waterworks, an entire wall of measuring equipment has now been replaced with a tailor-made, compact stainless steel cabinet containing a total of 14 sensor cubes and two automatic purification units to ensure reliable water analysis in a very compact space.

Unlike the glass probes widely used previously, the micro-chips for the sensors do not require constant replacement. This results in maintenance free and reliable operation.

Seven different water samples with the matching individ­ually combined sensor cubes are analysed in this system for turbidity, pH value, redox potential, conductivity and chlorine dioxide.

Thanks to automatic purification units, all parts in contact with water samples can be cleaned without manual intervention.

    The Type 8905 Online Analysis System continuously monitors and reports on up to six important water parameters on one platform. The continuous analysis of water parameters is a complex undertaking in practice. In most cases, there are different systems with individual displays, different operations and individual sensors. With the Type 8905...
