Datacentres grow enormously in numbers and want to pursue an increasingly green image. In this example of an advanced datacentre, rainwater is collected in large buffers. Primary, the air is being used to cool, however in case of good weather with high temperatures, water cooling is necessary.
The rainwater is not directly suitable for cooling. Pre-treatment requires the necessary steps, from filtration and disinfection to membrane filtration. Monitoring and surveillance are an essential part of this watertrain.
UV disinfection in this case takes place with P-series units, equipped with transmission measurement and automatic quartz cleaning. Operational security and minimum maintenance are guaranteed. Chemicals are avoided.
