Final Report - SHAKER (A smart homogenization approach improving process knowledge and papermaking competitiveness)

Project ID: 32352
Funded under: FP6-SME


During the 1990s, research approaches within water / pulp management, were mainly focused on the study of white-water detrimental components and on (bio) chemical-technological solutions to reduce them. Most paper machine problems have their origin in these dissolved/colloidal matters. The impact of these problems can be added up to EUR 1 billion per year. Efforts of the paper and board mills have already lead to a more closed water system, which, produce the accumulation of dissolved and colloidal material (DCM) in the water systems.

The objective of this project was to investigate the enhancement of sustainable management for stock (wood), energy (natural gas and green house effect) and water by stabilisation of the wet-end system of paper production based on a low cost sustainable concept.

Their final report emphasises that the intention of the SHAKER concept is not to solve all the water related problems but to avoid them (preventive action). The cause of process instability is bad homogenisation of pulp and water within storage / dilution tanks. In dead zones of tanks, certain parts of (inner) tank walls, etc., long residence times occur and create an increase of e.g. anaerobic biological activity. It also contains tables and images.
