"This progress report describes research conducted on pulp mill waste degradation in marine waters ... Engineering investigations ... have centered upon (a) treatment of mill wastes by dilution; (b) foam separation of strong wastes and (c) treatment of evaporator condensates by carbon adsorption. Biological studies have been concerned with development...
Two-stage sulfite pulping conditions were determined which
produced a high-yield high-hemicellulose pulp from red alder (Alnus
rubra Bong.). Those cooks with a bisulfite first-stage and an alkaline
second-stage produced pulps with the highest hemicellulose
content and the highest strength properties.
The major hemicellulose in red alder is 0-acetyl-(4-0-
methylglucurono)xylan. Removal...
Because of the organic nature and the natural foaming characteristics
of kraft mill effluents, it was decided to investigate the
feasibility of using foam separation as a method of treatment. The
treatment efficiency was evaluated by BOD and COD reductions as
well as the decrease in toxicity to marine life....
The degradation of kraft pulping wastes in estuarine waters
was measured in terms of the following parameters: five-day 20°C
B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel
(Mytilus edulis L.). The waste tested was the total effluent from a
combined pulp and paper mill producing 430 tons of...
"The purpose of this report is to evaluate alternate engineering plans for the disposal of wastes from a kraft process pulp and paper mill located at Toledo, Oregon. These alternatives have been evaluated from the standpoint of estimated annual cost and estimated resulting pollution of Yaquina Estuary in order to...
