Membrane technology added to Polish power plant

A third demineralization line using membrane and ion-exchange technology is to be added to the extension of the water treatment plant for the Patnów II power station in Poland.

Veolia Water Solutions & Technology announced on 13 November 2011 that its subsidiary Veolia Water Systems Sp zoo had signed a contract with Elektrownia Patnów II Sp zoo for a turnkey contract including design, construction, start-up and commissioning of the surface water treatment plant, which includes modernizing and upgrading two existing lines.

The demineralization plant based on ultrafiltration (UF) and reverse osmosis (RO) membranes will be one of the largest in Poland. Veolia says that application of its configuration with double RO proves unique in the energy sector.

Once modernized, the water treatment plant will supply process water to feed the new 464 MW power unit, as well as six existing 200 MW power units at Pątnów I Power Plant. The plant has a design capacity of 198 m³/h of demineralized water.

Two 300³m³/h Actifloc™ lines will be built within the water pretreatment stage, based on advanced processes of coagulation, flocculation and sedimentation leading to a 60% reduction of total organic carbon. The UF and double RO will be followed by mixed-bed ion exchangers.

Construction is scheduled to start in April 2013 and end in 2014.
