Energy Industry / Cooling Water

In the energy industry, water treatment solutions can be applied in different areas and also help to reduce costs.

Thermal power stations require large amounts of freshwater. Depending on the use, different purity classes are required. The water is generally taken from surface water. Large seasonal fluctuations of the contamination level may occur. In this case, lamella separators are the ideal devices for the pre-treatment / separation of particles.

A further application could be a slow decarbonisation, where the fresh water is not only softened but also purified.

In coal-fired power stations slag results from combustion of coal. After leaving the oven, the slag is quenched with water and bursts into splinters of various sizes. Larger particles can be reused in the building industry. The finer particles remain in the water causing turbidity. When the water is reused without treatment, the particles cause precipitation in pipelines and nozzles and lead to blockage and disturbance. These particles can be separated by lamella separators. The water can be reused or pumped back into the receiving water.

Lamella separators are used in the energy production sector as well. The main fields are refinery (separation of particles and free oils) or coke production (separation of coal and tar).

Gravity-sand filters can be used for fine cleaning of cooling water. These filters are characterised by an automatic backwash process, which happens purely mechanical due to the siphon effect, without pumps, valves, control systems or that like.

Further applications for Leiblein assemblies are the cleaning of exhaust or flue-gas wet-washers or miscellaneous belt filters for different filtration tasks. These include the filtration of washing or sawing water used for operation or dismantling of nuclear reactors. The filters are also suitable for biogas or pyrolysis plants.


  • compact design, less space required
  • longer service life of subsequent membrane systems
  • reacts to fluctuations of contamination levels
  • low maintenance-, operation- and cleaning-effort
  • low wear and tear
  • minimum energy and chemical consumption
  • high degree of sludge drainage
