Purifying River Water for Board Manufacture with DynaSand®
IGGESUND Paperboard uses some 22 megalitres of raw water per day in the manufacture of 260,000 tonnes of folding boxboard at its Workington plant. To ensure the continuity of a high quality water supply, Iggesund decided to manage the treatment on its own site, using Hydro International’s DynaSand® filtration plant to handle automatically the large volumes within a very small footprint and requiring minimal supervision.  “The river water is extracted by a utilities company from the river and pumped to large underground reservoirs. It then flows under gravity to the mill where the underground pipeline passes close to our wastewater plant, so it made sense to locate the raw water treatment plant there. Although the project required major civil work including cutting back into the hill side, the vertical configuration of the DynaSand® enabled us to locate all 28 units plus the Hydro Lamella Plate Clarifier and dosing equipment there.” |
