| Abstract |
The principal objective of this project was to determine if contact between effluent from a Kraft pulp mill and pine chips would reduce the water pollution characteristics of the waste liquor. The experimental work was divided into two phases: (1) a small scale laboratory investigation of contacting dilute waste liquor with chips; (2) a pilot-scale investigation of filtering waste liquor through a column and a pile of chips. It was found that contact of alkaline waste liquor, or even distilled water, with pine chips extracted organic matter from the chips which had a considerable BOD. This extract corresponded to a pollution load of about 3-11 lbs. BOD per ton of dry wood. Alkalinity, pH, and intensity of color of the waste liquor were somewhat reduced by the contact. These reductions are, however, too small to have any practical application in effluent treatment. It can, in general, be concluded that contact of alkaline waste liquor, or water, with wood chips extracts soluble organics and adds pollutional materials to the effluent stream. (Author) |
