THE METHOD OF DENSITY DETERMINATION OF POST-COAGULATION SEDIMENT WITH THE USE OF X-RAY MIVROTOMOGRAPHY
Keywords:
coagulation, density determination, X-ray tomography.Abstract
In this paper computed tomography was applied to determine the density of sediments from the water treatment process. Coagulation process caused the destabilisation of the dispersion, and particles had different shapes, sizes and structures. The density of particles had an impact on the settling velocity and is very difficult to be described mathematically. This article presents the method of X-ray microtomography (XMT) application for dried and pressed sediment. The sample volume was obtained through X-ray and image processing. The correct determination of the sample volume depends on a correct number of thresholds. The image processing was performed with the use of the LabVIEW environment and the Vision module. The paper presents the results of tests and boundary parameters for the pressing and image process.
