Abstract
The report describes a computer program that calculates atmospheric emissions from counterflow cooling towers when using pretreated coal gasification wastewaters as tower makeup water. Air stripping and biological oxidation are both incorporated into the mathematical model as possible contaminant removal mechanisms. Confirmation of model predictions was demonstrated by a 30-cm square by 91-cm high laboratory cooling tower using both simulated and real pretreated coal gasification wastewaters. Stripping of volatile components was shown to be the primary contaminant removal mechanism. Cycles-of-concentration (i.e., the ratio of makeup water flowrate to blowdown flowrate) is the major tower operating parameter influencing the amount of volatile contaminants remaining in the blowdown.
