Abstract: Significant progress was made during the past quarter in establishing the operability and reliability of major pieces of equipment needed for the production of protein and methane from spent sulfite liquor (SSL). Batch ozonations of SSL were conducted at times varying from 1 to 6 hours at pH's in the range of 10 to 2. These screening experiments consistently indicate that low ph's favor the breakdown of SSL into organic fragments which are more easily assimulated by micro-organisms. Approximately 23% of the organics are oxidized at all pH levels indicated that pH has no effect on the total oxidation of SSL. As was expected total sulfur content of SSL is not measurably altered by ozonation. The intense brown color of SSL is appreciably removed during ozonation. The contents of the reactor assume a light brownish-yellow hue during the course of a 4 hour ozonation treatment. Attempts to quantify the reduction have not been successful to date.
