| Abstract |
The first part of the study evaluates methods for the determination of deoxygenation (biodegradation) rates of polluted waters in Puerto Rico. The experimental part of the study was divided into three phases. The first phase consisted in working with the waste as it came from the particular source to determine its value of K (biodegradation constant) in its original state. The second and third phases of the study consisted in diluting the waste with natural river and sea water to simulate the condition of the waste when discharged into a natural body of water. The degree of dilution does not seem to have any significant effect. On the other hand, when the dilution water is sea water the value of K tends to be higher than when the waste is diluted in fresh water. (Author) |
