Slime growth evaluation of treated pulp mill waste
1971
Anderson, Arthur Wallace | Beierwaltes, G. A.
The introduction of sulfite waste liquors into streams often leads to the development of unsightly masses of biological slime dominated by Sphaerotilus. One approach for controlling the development of Sphaerotilus in streams receiving pulp mill wastes has been to employ biological methods for treating wastes before release into a receiving stream. The study evaluates the slime growth potential of pulp mill wastes treated by various methods of biodegradation. Wastes were tested both before and after secondary treatment in order to determine the type of biodegradable material present in the influent, determine the extent of fermentation during treatment, and the amount of biodegraded fermentable compounds discharged in the effluent. These studies were carried out in an effort to define total carbon, readily fermentable carbon, and to design a reasonably accurate and sensitive method for predicting adequate water quality presently measured by BOD.

Dissolved and particulate organic carbon in some Colorado waters
1971
Reed, Edward B.
Instantaneous amounts of organic carbon, both particulate and dissolved, in a number of freshwaters ranging from unproductive tarns to moderately productive reservoirs were measured by acid-persulfate digestion and infrared absorption. Organic carbon was designated as net seston carbon, filter seston carbon, or dissolved carbon based on filtering techniques. Repeated sampling showed amounts of organic carbon, either dissolved or particulate, fluctuated considerably over short periods of time; the dissolved fraction probably varying less than particulate forms. Almost daily measurements in samples incubated over three week periods also revealed erratic changes, with no clear reduction in total organic carbon. The data have descriptive value, although they cannot, at this time, be related satisfactorily to the general limnological knowledge.
