Success Story: Everswinkel Waterworks
In many waterworks the addition of oxidation air is performed manually by means of simple mechanical valves. With this procedure, an experienced waterworks supervisor can guarantee the quality of the drinking water beyond doubt – however, the procedure can neither be traced nor documented. If the composition or quantity of the drinking water fluctuates, manual readjustment is necessary, which is costly and time-consuming.
The fluid technology specialist Bürkert worked together with planning specialists and drinking water experts to develop a ready-to-connect solution for automated metering of oxidation air. The oxidator box operates on the basis of a high-performance, flexibly configurable mass flow controller. The compact system solution can automatically regulate the gas quantity needed for oxidation based on different process parameters, to achieve optimal results with minimal gas consumption. In addition to constant water quality and documented, traceable processes, the automated oxidation air metering system also offers substantial economic benefits due to reduced oxygen consumption and optimised operation of the compressors during metering of the air.
