A modified equation from that of Nancollas and Reddy is presented to describe the rate of calcium removed from water in CacO3; precipitation. The mass of CaCO3; precipitated at any moment was obtained by monitoring pH and utilizing this in the equilibrium equations for the Ca - H2CO3 system including ion pairing and ionic strength effects. Both batch and back mixing steady state conditions were studied. The precipitation rate constant was found to be independent of pH, and functionally related to the state of initial supersaturation in the batch tests and the state of supersaturation in the steady state tests. Both steady state and batch tests gave the same dependence of the precipitation rate constant with supersaturation. 2015-02-11T14:03:59Z 2015-02-11T14:03:59Z 1975 Master Thesis Masters MSc http://hdl.handle.net/11427/12430 eng application/pdf Department of Civil Engineering Faculty of Engineering and the Built Environment University of Cape Town |
