The sedimentation analysis method is based on the measurement of the deposition rate of suspended solids depending on their equivalent diameter. The use of sedimentation for disperse systems is limited by their size, as microscopic dust particles have low deposition rates and are difficult to analyze. Therefore, for finely dispersed systems, the authors propose a method of sedimentation analysis using portable cameras that record the deposition process and break it down into frames. The images obtained frame by frame are translated with the help of a graphic editor into binary (black and white) format, which is able to process the software. The experimental data obtained are presented in the form of tables and distribution functions.
