Through constant research and thanks to the experience acquired, Culligan has perfected original leading-edge technologies in the municipal water sector.

Hundreds of Water Supply Authorities world-wide have chosen Culligan filtration systems, which allow constant quality and outstanding flexibility thanks to their modular design, and considerable savings in purchase and operating costs.

For the various treatments, these systems adopt specific minerals or multi-layer beds consisting of special minerals of selected particle size and specific weight, guaranteeing exceptional performance in terms of quality and cycle.

The range of Culligan filtration systems is at the service of waterworks with the most widely varying delivery rates – from the few cubic meters/hour of the water supply for an isolated community to the thousands of cubic meters/hour of a large town – and is able to deal with water with the most diverse characteristics: turbidity, organic matter, presence of Iron and Manganese, acidity and Ammonia.

Culligan filtering systems can make the silty water of a river crystal clear, remineralise the distilled water of a power station, and recycle wastewater for industrial use downstream of the biological treatment plant.
