In power plants, unpurified water is used both for steam production and as a cooling medium (e.g. nuclear and fossil fuel power plants). In order to increase the electrical efficiency of these power plants, it is necessary that the recovered process water is freed of elements considered pollutants or harmful to the process.

To this end, Diemme® Filtration has consolidated its experience in this field, building up an extensive list of references in various parts of the world.

Main applications of Diemme Filtration in the energy and power sector

In particular, in gas, oil or coal-fired thermoelectric power stations, the fumes must be treated as they can contain a number of dangerous substances. In these cases, the vapours are desulphurised by wet treatment with lime and limestone, generating a sludge containing mainly calcium sulphate, ash, hydroxides, heavy metals (e.g. FGD, DeSOx).

The filter press technology is the most consolidated and versatile for this type of application, achieving, with high reliability, high performance dewatering and treatment of industrial sludge.

Diemme® Filtration’s ability to adapt to the high standards required by the various installations, both in terms of design and choice of components and materials, should be emphasised.

Within these plants, the filter press is also part of the purification of water coming from different areas and flowing to the physical-chemical treatment plant.
