Abstract
The report discussed an attempt to find a better method of disposing of the ever accumulating sludge which comes from the clarifiers when the solids are removed from the effluent waters of a pulp mill. The objective was to determine if sludge could be used as part of the fiber mix used to make corrugating medium. Sludge from three different types of mills was added in quantities of 10, 20, and 40 per cent to commercial corrugating medium furnish (fiber mix). It was found that the addition of sludge to the commercial furnish reduced the flat crush strength. However, if the useful fiber in sludge is substituted for some of the other sources of chemical fiber which is mixed with the semi-chemical pulp, a corrugating medium with acceptable flat crush strength may be possible.
