ANDRITZ to supply effluent and sludge treatment line to Holmen Iggesund Paperboard Ltd.
International technology group ANDRITZ has received an order from Holmen Iggesund Paperboard Ltd. to supply a state-of-the art primary effluent and sludge treatment line for its mill in Workington, UK. Start-up is scheduled for the first quarter of 2023. The mill will completely replace the existing primary effluent treatment plant to improve the efficiency of the system and reduce the level of total suspended solids (TSS) in the outfall. ANDRITZ will supply a tailormade technological solution, including channel screening, clarifying, automated flocculant and coagulant dosing, and sludge dewatering: *ANDRITZ Aqua-Screen channel screens specially designed for handling wastewater streams will ensure effective coarse screening and removal of large contaminants from the influent to the clarifiers. *Clarifiers will be installed to ensure efficient solid-liquid separation for coastal discharge. The clarifier tanks will be raised off the ground on legs to facilitate operation and maintenance activities. *State-of-the-art sludge handling line, including proven ANDRITZ gravity tables prior to ANDRITZ sludge screw presses for minimum flocculant consumption, lowest solids load in the filtrate and highest possible sludge dryness.
