On the way to better water quality

Two groundwater wells supply a town of 6,000 inhabitants with water. In one of the wells an excess of heavy metals was measured for a short time. In the surrounding area there are landfills for household waste and contaminated sites where heavy metals and organic substances occur in high concentrations. In addition, pesticides have been detected, presumably from wine-growing in this area.
The drinking water quality should be ensured by taking suitable treatment steps.

PWT solutions

Construction and commissioning of a water treatment plant adapted to the pollutants already detected and potentially occurring in the future.

The new treatment concept was integrated into the existing plant and also connected to the electrical and control systems.
