Weholite as a process water outlet for a mill

Plastic pipe withstands mill’s process water

Stora Enso’s Imatra mill, located in southeast Finland, annually produces one million tonnes of packaging paper and board. The Imatra mill’s two production units produce raw materials for cartons, in which juice and milk are packaged. Board is also used to produce paper cups, as well as cigarette and candy packages. Board for the graphics industry is used to produce cards, covers and luxury packages.

Stora Enso’s Imatra mill, located in southeast Finland, annually produces one million tonnes of packaging paper and board. The Imatra mill’s two production units produce raw materials for cartons, in which juice and milk are packaged. Board is also used to produce paper cups, as well as cigarette and candy packages. Board for the graphics industry is used to produce cards, covers and luxury packages.

The process water required in the manufacture of board and paper has thus far run through concrete channels to the treatment process facility, after which the water has been discharged into Lake Saimaa. The hot water that contains chemicals has worn down and eroded the concrete structures so much that a new solution had to be found for transporting the process water.

The project was assigned to Efora, an enterprise jointly owned by Stora Enso and ABB. The company specialises in providing the industry with maintenance and other services that secure smooth running and uninterrupted operations at mills.
