Antti Koulumies, the new Senior Vice President of UPM Timber, stepped into his position in early June, at a point when the timber business is booming. At the same time, the carbon footprint and effect on biodiversity of raw materials are ever more important to customers. Koulumies believes that UPM Timber, as a pioneer of responsible practices in the timber industry, has everything it needs to meet customer expectations now and to further develop in the future. “UPM Timber’s product – timber from responsibly grown forests – is very much in tune with my own values. All four of our sawmills run on renewable energy, and our timber products sequester carbon throughout their lifespan”, he explains.
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.
The entire key equipment will be provided with a special surface coating to protect against the harsh coastal environment at the Workington mill.
The scope of supply also comprises field instruments, tanks, agitators, and process pumps as well as installation and service support after commissioning to maintain highest availability of the plant.
As part of the Holmen Group, Holmen Iggesund Paperboard Ltd. is a manufacturer of premium paperboard for various packaging products and focuses strongly on sustainable production processes.
