| Summary, etc. | The presence of silica in industrial water poses a serious problem to the water engineers. This study was conducted primarily to investigate the potential of calcium and magnesium for removing silica from waters intended for industrial use, at silica concentrations approaching amorphous silica solubility of 120 mg/t Si02{u2022} Both the laboratory scale batch and continuous flow studies were conducted. The reaction of both calcium and magnesium with silica was found to be of the first-order. For magnesium, the rate constant k, was found to be +0.0655 min and optimum pH of 10 and an alkalinity of 125 mg/t CaC03. Thus the rate equation can be expressed as ln C/Co-1 = -0.0655 t. For calcium, the rate constant k, was found to +0.0277 min an optimum pH of 11. The rate equation can be written as ln C/C0 = -0.0277 t. For the continuous flow studies, the removal of silica by magnesium and calcium was found to be affected by the detention time and the re cycle rate, nevertheless, the mixing intensity has no significant effect on the removal of silica by magnesium and calcium. Since the kinetics of the reaction was known, the equation -t 1 Cio CMF = k (Co - 1) can be used to predict the effects of these process parameters. |
