Wind has an important effect on the behavior of ponds as it induces vertical mixing of the pond contents. Good mixing ensures a more uniform distribution and higher dispersion number within the pond and hence a better degree of waste stabilization. This study developed a mathematical model for the prediction of Coliform bacteria ( ce /co) on waste stabilization pond performance. The model was d...
A comprehensive investigation of the nitrogen cycle in the Delaware River was carried out using 15N tracers to measure rates for important transformations of nitrogen. Daily, depth-averaged 15N rates for the principal inorganic nitrogen species were consistent with rates derived from longitudinal profiles of concentration in the river. The data indicated that nitrification was a rapid, irrevers...
