Automatic filter for fluctuating fibre concentration
D&D has provided an automatic self-cleaning filter type Filterautomat DDF DN 200 / PN 10 to filter process water with fluctuating fiber concentration for a paper mill. With the installed filter we handle a flowrate of 200 m³/h with a filter fineness of 300 µm.
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.
Better values – Water treatment for the aluminum industry
In the aluminum industry, various aluminum minerals are employed to produce what is referred to as "primary aluminum" for downstream industries. This aluminum is used, for example, in the automotive and packaging industries. The possible applications are almost limitless.
