Sažetak
This study has examined the possibility of using the anionic 831A flocculent, produced by a Dutch firm Hercules, in tracing the rate of sedimentation of magnesium hydroxide obtained from seawater by 80% substoichiometric precipitation. The purpose of this study was to define the optimum conditions for sedimentation of magnesium hydroxide from seawater based on settling properties of magnesium hydroxide suspension in discontinuous precipitation. Examinations were made with different quantities of the 831A flocculent, and at different degrees of completeness of precipitation (70 % and 100 % precipitation) to determine the optimum quantity of the 831A flocculent during the sedimentation process. The results indicate significantly faster sedimentation of magnesium hydroxide obtained by precipitation with the smaller quantity of the precipitation agent than that required stoichiometrically, which is explained by the model of the Mg(OH)2 particle. From the results obtained for discontinuous conditions, one can apply the Kynch theory to calculate the continuous thickener.
