Abstract
Two different solutions of the dispersed flow model of the waste stabilization pond based on two different sets of boundary conditions were compared and analyzed statistically. These solutions, used in the prediction of the coliform reduction in the pond, were based on Hulbult's and Danckwerts' sets of boundary conditions. Although Danckwerts' set of boundary conditions is more mathematically consistent than Hulbult's, the solution based on the latter is simplier. Besides, statistical analysis at the 0.01 level of significance showed that there is little to choose between the two in terms of accuracy. Also, the two solutions gave similar values of correlation coefficient, standard error, intercept and regressed slope.
