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.

For a pumped storage power plant at the Eder in Hessen, D&D has commissioned a filter station consisting of two automatic backwashable filter units, type Filterautomat DDF, (coarse and fine filtration with 3 mm and 200 µm). The mechanical seal water of the turbine and the control water of the pump are filtered.

The Filterautomats DN 200 / PN 63 were mounted in series on a frame to save space. This automatically backwashable stage filtration replaces the previous manual filters and thus minimises costly maintenance and servicing work.

The special feature of this filter station is the design for alternating stress due to possible pressure fluctuations (hydraulic short circuit) and the welded steel construction for pressure stage PN 63.



Frequently
Asked Questions

DANGO & DIENENTHAL Filtertechnik manufactures automatic filters, manual filters, and separators for solid-liquid separation. The systems are used to filter cooling water, river water, and process water, among other applications. The right solution depends on the fluid, particle load, flow rate, required filtration rating, and operating conditions.

An automatic filter is ideal when the process must operate continuously and manual cleaning should be minimized. Automated cleaning maintains filtration performance, reduces the workload for operating personnel, and increases plant availability.

Manual filters are suited to applications that require simple, robust, and cost-effective filtration. Depending on the process, they can be used as primary filters, prefilters, or protective filters.

Our filtration solutions are used across nearly every industrial sector, including steel, paper, and chemicals; power generation; wastewater treatment; building services; geothermal and offshore applications; food production; drinking water treatment; and irrigation.

Selection is based on your application, fluid, flow rate, required filtration rating, solids load, and installation conditions. DANGO & DIENENTHAL supports you with the technical sizing and selection of the right filtration solution.

Yes. DANGO & DIENENTHAL provides service, maintenance, retrofits, and overhauls for existing filter systems. These services allow systems to be adapted to current requirements, extend equipment life, improve reliability, and avoid the cost of premature replacement.
