A short introduction to the SHAKER project COOP-CT-032352
The instability in the wet-end system causes a lot of problems and costs.

Most common approach is to solve these problems (corrective action). For corrosion that is the development of a corrosion inhibitor, for scaling a scaling agent, and for stickies a fixing agent or deposit control chemical and/or monitor etc.

The intention of the SHAKER concept is not to solve all these problems but to avoid them (preventive action). The cause of process instability is bad homogenization 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. biological activity. This causes gradients of microorganisms, degredation products and will finally generate the mentioned problems. All have a dissolved and colloidal nature.

Therefore this concept is a different approach to former adapted improvement options, because the SHAKER concept deals with the source of the problems and not with the consequences being the problems itself.
