RO included in Czech powerplant water treatment upgrade

Wabag Brno has begun modernisation of the water treatment plant at the Prunéřov power station in the Czech Republic, involving clarification, filtration, reverse osmosis, softening and demineralisation.

The 5 x 210 MW coal-fired powerplant project was controversially given environmental approval by the Czech government on 29 April 2010.

Using feedwater from a nearby river, the plant will produce 3,600 m³/d of boiler feed and condensate water, as well as 36,000 m³/d of cooling water. Appropriate water conditioning prevents deposits in the boiler pipes and corrosion in the steam and condensate system is also minimised.

The work is to be completed while the power plant is in operation and the commissioning of the new water treatment system for the first unit is already scheduled for December 2010. The client is Královopolská RIA AS, Brno, which as the general contractor, is responsible to the energy supplier ČEZ for the complete overhaul of the power station.
