The main objective of this thesis was to bring the theoretical and practical aspects of secondary settling tank developments closer together. This was achieved firstly, by evaluating and developing empirical relationships from which the flux theory constants may be derived from simpler sludge settleability measures; and secondly, by developing a computer model for the simulation of dynamic behaviour of full scale secondary settling tanks. The model was initially developed for and tested on laboratory scale data. It was then calibrated with full scale data and used to verify the flux theory by comparing the simulated predictions and the measured results. The simulations demonstrated that a calibrated and verified dynamic settling tank model based on the flux theory and incorporating various refinements such as turbulent diffusivity implicitly encompasses such features of secondary settling tank behaviour such as maximum underflow concentration and sludge storage concentration and capacity. It was concluded that the simulation program is an improvement on previous simulation programs based purely on the steady state flux theory and should be used as a starting point for developing design theories based on the flux theory. 2014-10-17T07:25:20Z 2014-10-17T07:25:20Z 1993 Doctoral Thesis Doctoral PhD http://hdl.handle.net/11427/8453 eng application/pdf Department of Civil Engineering Faculty of Engineering and the Built Environment University of Cape Town |
