Better Values – More Power

For power generation in pumped storage power plants, manual and/or automatic filters are used for bearings on turbines or pumps that are sealed or cooled with water. In order to protect the bearings and seals as best as possible and to reduce wear, a high level of water purity must be ensured.

Component protection in a pumped storage hydroelectric power plant

In addition to power generated from fossil fuels, the share of solar and wind power in the grid is steadily increasing. In the future, therefore, it will become increasingly important to provide flexible energy storage to compensate for fluctuations in the grid due to the weather.

Water treatment in mining

Mining refers to the extraction of mineral resources from the upper layer of the Earth's crust. As part of the extraction process and the depth required for mining raw materials, water is inevitably encountered underground. Depending on the quantity, this water can flood entire tunnels and pose a considerable hazard to the miners.
